This

...

is

...

based

...

on

...

the

...

BND

...

tool

...

from

...

Peter

...

Kriens.

...

The

...

way

...

BND

...

works

...

is

...

by

...

treating

...

your

...

project

...

as

...

a

...

big

...

collection

...

of

...

classes

...

(e.g.,

...

project

...

code,

...

dependencies,

...

and

...

the

...

class

...

path).

...

The

...

way

...

you

...

create

...

a

...

bundle

...

with

...

BND

...

is

...

to

...

tell

...

it

...

the

...

content

...

of

...

the

...

bundle's

...

JAR

...

file

...

as

...

a

...

subset

...

of

...

the

...

available

...

classes.

...

This

...

plugin

...

wraps

...

BND

...

to

...

make

...

it

...

work

...

specifically

...

with

...

the

...

Maven

...

2

...

project

...

structure

...

and

...

to

...

provide

...

it

...

with

...

reasonable

...

default

...

behavior

...

for

...

Maven

...

2

...

projects.

Assume that we have a simple bundle project that has a pubic API package an several implementation packages, such as:

we

a

Features

The BND library underlying the plugin defines instructions to direct its behavior. For this Maven plugin, these instructions are issued in the plugin configuration section of the POM file, as was illustrated above. BND recognizes three types of instructions:

  1. Manifest headers - Any instruction that starts with a capital letter will appear in the resulting bundle's manifest file; the value for the header will either be copied, augmented, or generated by BND depending on the instruction.
  2. Variables - Any instruction starting with a lowercase letter is assumed to be a variable in the form of a name-value pair, such as version=3.0, that can be used for property substitution, but is not copied to the manifest.
  3. Directives - Any instruction starting with a '-' character is considered to be a directive that informs BND to perform some special processing and is not copied to the manifest.

The remainder of this section covers the most important aspects of BND's instructions; for complete details refer to the BND documentation.

Instructions

<Export-Package>

The <Export-Package> instruction is a list of packages for the bundle to export. These packages are copied into the resulting bundle JAR file from the available classes (i.e., project classes, dependencies, and class path); thus, it is possible to include classes into your bundle that are not associated with source files in your project. <Export-Package> can be specified with package patterns using the '*' wildcard. Also, it is possible to exclude packages using negation by starting the package pattern with '!'. Thus, non-negated patterns indicate which of the available packages to include in the bundle, whereas negated patterns indicate which should not be included in the bundle.

The list of package patterns is ordered and earlier patterns are applied before later patterns. For example, if you specify "org.foo.*,!org.foo.impl" the second pattern has no effect since all org.foo packages have already been selected by the first pattern. Instead, you should specify "!org.foo.impl,org.foo.

...

*

...

",

...

which

...

will

...

export

...

all

...

org.foo

...

packages

...

except

...

org.foo.impl

...

.

...

Following

...

standard

...

OSGi

...

R4

...

syntax,

...

package

...

patterns

...

can

...

include

...

both

...

directives

...

and

...

attributes,

...

which

...

will

...

be

...

copied

...

appropriately

...

into

...

the

...

generated

...

Export-Package

...

manifest

...

header.

...

Besides

...

explicitly

...

listing

...

package

...

version

...

attributes,

...

BND

...

will

...

also

...

determine

...

package

...

versions

...

by

...

examining

...

the

...

source

...

JAR

...

file

...

or

...

from

...

packageinfo

...

files

...

in

...

the

...

package

...

directory.

...

<Private-Package>

...

The <Private-Package>

...

instruction

...

is

...

similar

...

in

...

every

...

way

...

to

...

the

...

<Export-Package>

...

instruction,

...

except

...

for

...

the

...

fact

...

that

...

these

...

packages

...

will

...

not

...

be

...

exported

...

by

...

the

...

bundle.

...

If

...

a

...

package

...

is

...

selected

...

by

...

both

...

the

...

export

...

and

...

private

...

package

...

headers,

...

then

...

the

...

export

...

takes

...

precedence.

...

<Include-Resource>

...

The <Include-Resource>

...

instruction

...

is

...

a

...

list

...

of

...

arbitrary

...

resources

...

that

...

should

...

be

...

copied

...

into

...

the

...

bundle

...

JAR

...

file.

...

The

...

specified

...

resources

...

are

...

declared

...

as

...

clauses

...

that

...

can

...

have

...

the

...

following

...

forms:

{
No Format
}
clause ::= assignment | inline | simple
assignment ::= PATH '=' PATH
simple ::= PATH
inline ::= '@' PATH
{noformat}

For

...

the

...

<Include-Resource>

...

instruction,

...

actual

...

file

...

paths

...

are

...

relative

...

to

...

the

...

pom.xml

...

,

...

while

...

file

...

copy

...

destinations

...

are

...

relative

...

to

...

the

...

root

...

of

...

the

...

resulting

...

bundle

...

JAR

...

file.

...

In

...

the

...

case

...

of

...

assignment

...

or

...

simple

...

forms,

...

the

...

PATH

...

parameter

...

can

...

point

...

to

...

a

...

file

...

or

...

directory.

...

The

...

simple

...

form

...

will

...

place

...

the

...

resource

...

in

...

the

...

bundle

...

JAR

...

with

...

only

...

the

...

file

...

name,

...

i.e.,

...

without

...

any

...

path

...

component.

...

For

...

example,

...

including

...

src/main/resources/a/b.c

...

will

...

result

...

in

...

a

...

resource

...

b.c

...

in

...

the

...

root

...

of

...

the

...

bundle

...

JAR.

...

If

...

the

...

PATH

...

points

...

to

...

a

...

directory,

...

the

...

entire

...

...

hierarchy

...

is

...

copied

...

into

...

the

...

resulting

...

bundle

...

JAR

...

file

...

relative

...

to

the

If

a

resource

...

must

...

be

placed

a

...

of

(including

if

...

and

the

second

...

path

is

the

to

The

The

for

This

rarely

specified.

However,

cases

when

there

import,

such

an

import

...

can

be

removed

...

by

using

pattern.

The

the

Default Behavior

To use this plugin, very little information is required by BND. As part of the Maven integration, the plugin tries to set reasonable defaults for various instructions. For example:

  • <Bundle-SymbolicName> is computed using the shared Maven2OsgiConverter component, which uses the following algorithm:
    Get the symbolic name as groupId + "." + artifactId, with the following exceptions:
    • if artifact.getFile is not null and the jar contains a OSGi Manifest with Bundle-SymbolicName property then that value is returned
    • if groupId has only one section (no dots) and artifact.getFile is not null then the first package name with classes is returned. eg. commons-logging:commons-logging

...

    • ->

...

    • org.apache.commons.logging

...

    • if

...

    • artifactId

...

    • is

...

    • equal

...

    • to

...

    • last

...

    • section

...

    • of

...

    • groupId

...

    • then

...

    • groupId

...

    • is

...

    • returned.

...

    • eg.

...

    • org.apache.maven:maven

...

    • ->

...

    • org.apache.maven

...

    • if

...

    • artifactId

...

    • starts

...

    • with

...

    • last

...

    • section

...

    • of

...

    • groupId

...

    • that

...

    • portion

...

    • is

...

    • removed.

...

    • eg.

    • org.apache.maven:maven-core

Since

the

creates

bundles

it

hard-codes

Bundle-ManifestVersion

be

'2'.

...

Additionally,

it

...

generates

imports

for

every

export

to

ensure

package

substitutability,

which

is

very

important

when

It

is

these

(except

...

The

...

first

...

step

...

in

...

the

...

process

...

of

...

using

...

the

...

plugin

...

is

...

downloading

...

and

...

installing

...

the

...

latest

...

version

...

of

...

the

runtime.

...

The

...

can

found

...

at

the

website

...

.

Using the Plugin

To use the maven-bundle-plugin,

...

you

...

first

...

need

...

to

...

add

...

the

...

plugin

...

and

...

some

...

appropriate

...

plugin

...

configuration

...

to

...

your

...

bundle

...

project's

...

POM.

...

Below

...

is

...

an

...

example

...

of

...

a

...

simple

...

OSGi

...

bundle

...

POM

...

for

...

Maven2:

There

are

...

two

...

main

things

...

to

...

note:

...

(1)

...

the

...

must

...

be

...

"bundle"

...

and

...

(2)

...

the

...

and

configuration

...

must

...

be

will

Consider

this

more

...

real-world

example

...

using

...

Felix'

...

Log

implementation.

...

The

...

Log

...

Service

...

project

...

is

...

comprised

...

of

...

a

...

single

...

package:

org.apache.felix.log.impl

.

...

It

...

has

...

a

dependency

...

on

the

as

well

...

as

...

a

Notice

...

that

...

the

...

<Export-Package>

...

instruction

...

specifies

...

that

the

bundle

...

exports

...

the

...

Log

...

package,

...

even

...

though

...

this

...

package

...

is

...

not

...

contained

...

in

...

the

...

bundle

...

project.

...

By

declaring

this,

the

will

copy

...

the

...

Log

...

package

the

...

file.

...

This

...

is

useful

in

this

case

because

you

can

goal

...

to

"bundle"

...

then

  • remote-clean - cleans a remote OBR, removing missing bundles
    configuration options:
    • remoteOBR name of remote OBR, defaults to NONE (which means no remote cleaning)

The default goal bundle will be initialized by setting the <packaging> entry to "bundle".

The following features are only available from version 1.2.0 onwards

Embedding dependencies

The Maven Bundle Plugin supports embedding of selected project dependencies inside the bundle by using the <Embed-Dependency> instruction:

Code Block
xml
xml
{noformat}
** _{{groupId}}_ Maven groupId for the bundle, taken from _pomFile_ if given
** _{{artifactId}}_ Maven artifactId for the bundle, taken from _pomFile_ if given
** _{{version}}_ Maven version for the bundle, taken from _pomFile_ if given
** _{{packaging}}_ Maven packaging type for the bundle, taken from _pomFile_ if given
** _{{classifier}}_ Maven classifier type, defaults to none
** _{{pomFile}}_ optional Pom file describing the bundle
** _{{file}}_ bundle file, defaults to the bundle from the local Maven repository
** _{{obrXml}}_ optional additional properties for the bundle
** _{{ignoreLock}}_ ignore remote locking when updating the OBR

* *{{clean}}* - cleans the local OBR, removing missing bundles
configuration options:
** _{{obrRepository}}_ path to local OBR, defaults to _<local-maven-repository>_{{/repository.xml}}

* *{{remote-clean}}* - cleans a remote OBR, removing missing bundles
configuration options:
** _{{remoteOBR}}_ name of remote OBR, defaults to NONE (which means no remote cleaning)
** _{{obrRepository}}_ used when the remoteOBR name is blank, defaults to {{repository.xml}}
** _{{prefixUrl}}_ optional public URL prefix for the remote repository
** _{{altDeploymentRepository}}_ alternative remote repository, _id::layout::url_
** _{{obrDeploymentRepository}}_ optional OBR specific deployment repository.
** _{{ignoreLock}}_ ignore remote locking when updating the OBR

There are also new instructions available from the underlying BND tool, which continues to be improved independently; for the latest see [BND documentation|http://aqute.biz/Code/Bnd].

The default goal *{{bundle}}* will be initialized by setting the <packaging> entry to "bundle".

h1. The following features are only available from version 1.2.0 onwards

h2. Embedding dependencies

The Maven Bundle Plugin supports embedding of selected project dependencies inside the bundle by using the {{<Embed-Dependency>}} instruction:

{code:xml}
<Embed-Dependency>dependencies</Embed-Dependency>
{code}

where:

{
No Format
}
dependencies ::= clause ( ',' clause ) *
clause ::= MATCH ( ';' attr '=' MATCH | ';inline=' inline )
attr ::= 'groupId' | 'artifactId' | 'version' | 'scope' | 'type' | 'classifier' | 'optional'
inline ::= 'true' | 'false' | PATH ( '|' PATH ) *
MATCH ::= <globbed regular expression>
PATH ::= <Ant-style path expression>
{noformat}

The

...

plugin

...

uses

...

the

...

<Embed-Dependency>

...

instruction

...

to

...

transform

...

the

...

project

...

dependencies

...

into

...

<Include-Resource>

...

and

...

<Bundle-ClassPath>

...

clauses,

...

which

...

are

...

then

...

appended

...

to

...

the

...

current

...

set

...

of

...

instructions

...

and

...

passed

...

onto

...

BND.

...

If

...

you

...

want

...

the

...

embedded

...

dependencies

...

to

...

be

...

at

...

the

...

start

...

or

...

middle

...

of

...

<Include-Resource>

...

or

...

<Bundle-ClassPath>

...

then

...

you

...

can

...

use

...

{

...

maven-dependencies

...

}

...

,

...

which

...

will

...

automatically

...

expand

...

to

...

the

...

relevant

...

clauses.

...

The

...

MATCH

...

section

...

accepts

...

alternatives,

...

separated

...

by

...

|

...

,

...

and

...

can

...

be

...

negated

...

by

...

using

...

!

...

at

...

the

...

beginning

...

of

...

the

...

MATCH.

...

Use

...

*

...

to

...

represent

...

zero

...

or

...

more

...

unknown

...

characters

...

and

...

?

...

to

...

represent

...

zero

...

or

...

one

...

character.

...

You

...

can

...

also

...

use

...

standard

...

Java

...

regexp

...

constructs.

...

There

...

is

...

no

...

need

...

to

...

escape

...

the

...

.

...

character

...

inside

...

MATCH.

...

The

...

first

...

MATCH

...

in

...

a

...

clause

...

will

...

filter

...

against

...

the

...

artifactId.

...

some

...

examples:

Code Block

{code:xml}
<!-- embed all compile and runtime scope dependencies -->
<Embed-Dependency>*;scope=compile|runtime</Embed-Dependency>

<!-- embed any dependencies with artifactId junit and scope runtime -->
<Embed-Dependency>junit;scope=runtime</Embed-Dependency>

<!-- inline all non-pom dependencies, except those with scope runtime -->
<Embed-Dependency>*;scope=!runtime;type=!pom;inline=true</Embed-Dependency>

<!-- embed all compile and runtime scope dependencies, except those with artifactIds in the given list -->

<!-- inline contents of selected folders from all dependencies -->
<Embed-Dependency>*;inline=images/**|icons/**</Embed-Dependency>

matched

embedded

the

bundle

...

as

artifactId-version.jar

...

.

...

This

...

behaviour

...

can

...

be

...

modified

...

using

...

the

...

following

...

instructions:

...

  • <Embed-StripVersion>true</Embed-StripVersion>

...

  • -

...

  • removes

...

  • the

...

  • version

...

  • from

...

  • the

...

  • file

...

  • (ie.

...

  • artifactId.jar

...

  • )

...

  • <Embed-StripGroup>false</Embed-StripGroup>

...

  • -

...

  • adds

...

  • the

...

  • groupId

...

  • as

...

  • a

...

  • subdirectory

...

  • (ie.

...

  • groupId/artifactId-version.jar

...

  • )

...

  • <Embed-Directory>directory</Embed-Directory>

...

  • -

...

  • adds

...

  • a

...

  • subdirectory

...

  • (ie.

...

  • directory/artifactId-version.jar

...

  • )

...

Normally

...

the

...

plugin

...

only

...

checks

...

direct

...

dependencies,

...

but

...

this

...

can

...

be

...

changed

...

to

...

include

...

the

...

complete

...

set

...

of

...

transitive

...

dependencies

...

with

...

the

...

following

...

option:

Code Block
xml
xml


{code:xml}
<Embed-Transitive>true</Embed-Transitive>
{code}

If

...

you

...

want

...

a

...

dependency

...

inlined

...

instead

...

of

...

embedded

...

add

...

the

...

...

.

...

For

...

example

to

inline

If

you

a

...

dependency

with

...

<Embed-Dependency>

...

,

...

and

...

your

...

<Export-Package>

...

or

...

<Private-Package>

...

instructions

...

match

...

packages

...

inside

...

the

...

embedded

...

jar,

...

you

...

will

...

see

...

some

...

duplication

...

inside

...

the

...

bundle.

...

This

...

is

...

because

...

the

...

<Export-Package>

...

and

...

<Private-Package>

...

instructions

...

will

...

result

...

in

classes

being

in

the

even

though

...

they

also

exist

inside

the

...

If

you

want

to

...

export

...

packages

...

from

...

an

embedded

dependency

...

without

such

duplication

...

then

you

can

either

inline

the

dependency,

...

or

...

use

...

a

...

new

...

BND

...

instruction

...

called

...

<_exportcontents>

...

.

<_exportcontents>

...

behaves

...

just

...

like

...

Export-Package,

...

except

...

it

...

doesn't

...

change

...

the

content

the

Dependency

Plugin

...

to

handle

embedded

jars

...

in

Eclipse.

...

With

the

original

you

would

simply

you

may

create

a

which

to

the

ones

...

compiled

for

example

when

you

...

embed

the

classes

...

from

another

jar.

...

This

...

can

sometimes

...

cause

...

unforeseen

...

problems

...

in

...

Maven,

...

as

...

it

...

will

...

use

...

the

...

output

...

directory

...

(

...

target/classes

...

)

...

rather

...

than

...

the

...

final

...

bundle,

...

when

...

compiling

...

against

...

projects

...

in

...

the

...

same

...

reactor

...

(ie.

...

the

...

same

...

build).

...

The

...

easiest

...

way

...

to

...

get

...

around

...

this

...

Maven

...

'feature'

...

is

...

to

...

unpack

...

the

...

contents

...

of

...

the

...

bundle

...

to

...

the

...

output

...

directory

...

after

...

the

...

packaging

...

step,

...

so

...

the

...

additional

...

classes

...

will

...

be

...

found

...

where

...

Maven

...

expects

...

them.

...

Thankfully

...

there

...

is

...

now

...

an

...

easy

...

option

...

to

...

do

...

this

...

in

...

the

bundle:clean

...

Sometimes

...

you

...

would

...

like

...

to

...

clean

...

your

...

local

...

OBR

...

because

...

it

...

contains

...

bundles

...

that

...

are

...

no

...

longer

...

in

...

your

...

local

...

Maven

...

repository.

...

This

...

case

...

often

...

occurs

...

when

...

artifacts

...

were

...

deleted

...

manually.

...

The

...

maven-bundle-plugin

...

provides

...

a

...

simple

...

goal

...

to

...

check

...

for

...

missing

...

bundles,

...

and

...

remove

...

them

...

from

...

the

...

local

...

OBR.

...

configuration:

...

  • obrRepository path to local OBR,

...

  • defaults

...

  • to

...

  • <local-maven-repository>

...

  • /repository.xml

...

Example:

{

}
mvn bundle:clean
{noformat}

h2. 

bundle:index

...

The

...

index

...

goal

...

allows

...

the

...

creation

...

of

...

an

...

OBR

...

repository

...

based

...

on

...

a

...

set

...

of

...

jars

...

in

...

a

...

maven

...

repository.

...

Configuration:

...

  • obrRepository path to local OBR,

...

  • defaults

...

  • to

...

  • <local-maven-repository>

...

  • /repository.xml

...

  • urlTemplate template for generating urls for OBR resources
  • mavenRepository path to the maven repository, defaults to <local-maven-repository>

...

Possible

...

values

...

for

...

the

...

urlTemplate

...

are:

...

  • maven this will create a maven based url such as mvn:groupid/artifactid/version

...

  • pattern

...

  • with

...

  • the

...

  • following

...

  • placeholders:
    • %v bundle version
    • %s bundle symbolic name
    • %f file name
    • %p file path

Concurrent updates

With a remote OBR, several uploads may occur at the same time. However, the remote OBR is centralized in one file, so concurrent modification must be avoided. To achieve this, the plug-in implements a locking system. Each time the plug-in tries to modify the file it sets a file based lock. If it can't take the lock, it will wait and retry. After 3 attempts the upload process fails. To bypass this lock add -DignoreLock to the command-line (or add <ignoreLock>true<ignoreLock> to the configuration section of your Pom).

FTP protocol

Not all protocols are supported by Maven out of the box. For example the ftp protocol requires the wagon-ftp component. To enable the ftp protocol add this to your Pom:

Code Block
xml
xml

** {{%v}} bundle version
** {{%s}} bundle symbolic name
** {{%f}} file name
** {{%p}} file path
