The iPOJO Maven Plug-in is generally used with the BND Maven Plug-in (more details here). However the two configurations are completely separated. So, you can use all BND Maven plug-in features. The iPOJO configuration section can be used as previously written without any changes. However it requires that your metadata file is either inside src/main/ipojo or inside the src/main/resources folder and named "metadata.xml".

Execution

To manipulate your project, use the "mvn clean install" command. The output should be like:

Configuration Options

You can configure the localization of the iPOJO metadata file as following:

Div

class	pom

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-ipojo-plugin</artifactId>
    <version>1.6.0</version>
    <executions>
        <execution>
        <goals>
            <goal>ipojo-bundle</goal>
        </goals>
        <configuration>
             <metadata>ipojo/meta.xml</metadata>
        </configuration>
        </execution>
   </executions>
</plugin>

In the metadata element, you can specify your metadata file or directory. The given file path is relative to the root directory ("./ipojo/meta.xml"). If the specified location is a directory, all contained XML files will be used. By default, the plugin searches metadata files into the src/main/ipojo folder. If not found then it searches for target/classes/metadata.xml and ./metadata.xml.

Note: The directory support was introduced in the 1.7.0 version. Previously only one metadata file was found.
Compatibility: Before the 1.7.0, the set location was searched in all resource folders. This is no more supported because it's an anti-pattern.

The second option allows skipping annotations processing, by using the ignoreAnnotations element:

Div

class	pom

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-ipojo-plugin</artifactId>
    <version>1.6.0</version>
    <executions>
        <execution>
        <goals>
            <goal>ipojo-bundle</goal>
        </goals>
        <configuration>
            <ignoreAnnotations>true</ignoreAnnotations>
        </configuration>
        </execution>
   </executions>
</plugin>

You can also ignore embedded XML-Schemas to use external ones. To do so, add the ignoreEmbeddedSchemas. If set to true, the manipulator doesn't use embedded XML-Schemas:

Div

class	pom

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-ipojo-plugin</artifactId>
    <version>1.6.0</version>
    <executions>
        <execution>
        <goals>
            <goal>ipojo-bundle</goal>
        </goals>
        <configuration>
            <ignoreEmbeddedSchemas>true</ignoreEmbeddedSchemas>
        </configuration>
        </execution>
   </executions>
</plugin>

h2. Configuration Options

You can configure the localization of the iPOJO metadata file as following:
{div:class=pom}
<plugin>
&nbsp;&nbsp;&nbsp; <groupId>org.apache.felix</groupId>
&nbsp;&nbsp;&nbsp; <artifactId>maven-ipojo-plugin</artifactId>
&nbsp;&nbsp;&nbsp; <version>1.2.0</version>
&nbsp;&nbsp;&nbsp; <executions>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <execution>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <goals>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <goal>ipojo-bundle</goal>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </goals>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{color:red}<metadata>ipojo/meta.xml</metadata>{color}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </configuration>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;</execution>
&nbsp;&nbsp;&nbsp;</executions>
</plugin>
{div}
In the metadata element, you can specify your metadata files. This file must be either in the same directory than the POM file (project root) or in one of the resource folder of the maven project (for instance, "src/main/resources/ipojo/meta.xml").

The second option allows skipping annotations processing, by using the {{ignoreAnnotations}} element:
{div:class=pom}
<plugin>
&nbsp;&nbsp;&nbsp; <groupId>org.apache.felix</groupId>
&nbsp;&nbsp;&nbsp; <artifactId>maven-ipojo-plugin</artifactId>
&nbsp;&nbsp;&nbsp; <version>1.2.0</version>
&nbsp;&nbsp;&nbsp; <executions>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <execution>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <goals>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <goal>ipojo-bundle</goal>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </goals>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;{color:red}<ignoreAnnotations>true</ignoreAnnotations>{color}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </configuration>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;</execution>
&nbsp;&nbsp;&nbsp;</executions>
</plugin>
{div}

You can also ignore embedded XML-Schemas to use external ones. To do so, add the {{ignoreEmbeddedSchemas}}. If set to {{true}}, the manipulator doesn't use embedded XML-Schemas:
{div:class=pom}
<plugin>
&nbsp;&nbsp;&nbsp; <groupId>org.apache.felix</groupId>
&nbsp;&nbsp;&nbsp; <artifactId>maven-ipojo-plugin</artifactId>


&nbsp;&nbsp;&nbsp; <version>1.2.0</version>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;{color:red}<ignoreEmbeddedSchemas>true</ignoreEmbeddedSchemas>{color}

&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;</execution>
&nbsp;&nbsp;&nbsp;</executions>

{div}


h2. Generate the skeleton of your iPOJO bundle
The maven-ipojo-plugin provides a way to generate the skeleton of your project. To generate this structure, just launch the following command:
{code}
mvn org.apache.maven.plugins:maven-archetype-plugin:creategenerate \
-DarchetypeArtifactId=maven-ipojo-plugin \
-DarchetypeGroupId=org.apache.felix \
-DartifactId=ARTIFACT_NAME_OF_YOUR_PROJECT \
-DgroupId=GROUP_ID_OF_YOUR_PROJECT \
-DarchetypeVersion=VERSION_OF_YOUR_PROJECT \
-DpackageName=PACKAGE_NAME
{code}

This

...

command

...

generates

...

:

...

a

...

pom

...

file

...

(to

...

update),

...

the

...

and

...

src/main/resources

...

folders,

...

the

...

structure

...

of

...

your

name.

The generated project uses iPOJO annotation and is ready to be deployed.
