How to cut a new Apache Empire-db (incubator) release.
This document explains how to cut a new empire-db release. Since we normally do this in Linux I expect you to have a Linux enironment at hand. For windows users Cygwin might be a solution. This document is based on the Maven release documentation.
The release process takes about one hour to perform, don't do this is a hurry as it is important to perform each step in the correct order!
Before you get started
Setup
Make sure your system is set up correctly and that you have the needed credentials
- you have all Maven servers defined in your settings.xml. For more information, please refer to Committer settings. This is what mine looks like:
<?xml version="1.0"?> <settings> <servers> <!-- To publish a snapshot of some part of Maven --> <server> <id>apache.snapshots.https</id> <username>francisdb</username> <password>xxx</password> </server> <!-- To publish a website of some part of Maven --> <server> <id>apache.website</id> <username>francisdb</username> <filePermissions>664</filePermissions> <directoryPermissions>775</directoryPermissions> </server> <!-- To stage a release of some part of Maven --> <server> <id>apache.releases.https</id> <username>francisdb</username> <password>xxx</password> </server> <!-- To stage a website of some part of Maven --> <server> <id>stagingSite</id> <!-- must match hard-coded repository identifier in site:stage-deploy --> <username>francisdb</username> <filePermissions>664</filePermissions> <directoryPermissions>775</directoryPermissions> </server> </servers> <profiles> <profile> <id>apache-release</id> <properties> <gpg.passphrase>xxx</gpg.passphrase> </properties> </profile> </profiles> </settings>
- you have created your GPG keys. For more information, please refer to Making GPG Keys.
- you have a GPG client installed and on your shell's path. See http://www.gnupg.org/
.
- you have a Subversion 1.5+ client installed and on your shell's path. See http://subversion.tigris.org/
.
- you have a Java 1.4.2 JDK installed and on your shell's path. See http://java.sun.com/j2se/1.4.2/download.html
.
- you have set the environment variable MAVEN_OPTS=-Xmx512m
- you are using Maven 2.0.x or 2.2.1+, as Maven 2.1.x is known to produce wrong gpg pom signatures (see MGPG-14).
Make sure maven uses Java 5
Create a mvn5 shell script and add it to your PATH. This script makes sure you use Java 5 to build the release.
/usr/bin/mvn5
#!/bin/sh JAVA_HOME="/usr/lib/jvm/java-1.5.0-sun" mvn $@
test the script by running this command:
>mvn5 --version Apache Maven 2.2.1 (r801777; 2009-08-06 20:16:01+0100) Java version: 1.5.0_18 Java home: /usr/lib/jvm/java-1.5.0-sun-1.5.0.18/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux" version: "2.6.28-15-generic" arch: "amd64" Family: "unix"
Make sure that the Java version is 1.5.x!
Creating a new RC
Prepare the release
>mvn5 release:clean ... >mvn5 release:prepare ... [INFO] Checking dependencies and plugins for snapshots ... What is the release version for "Apache Empire-db Parent"? (org.apache.empire-db:empire-db-parent) 2.0.5-incubating: : What is SCM release tag or label for "Apache Empire-db Parent"? (org.apache.empire-db:empire-db-parent) empire-db-parent-2.0.5-incubating: : apache-empire-db-2.0.5-incubating-rc3 What is the new development version for "Apache Empire-db Parent"? (org.apache.empire-db:empire-db-parent) 2.0.6-incubating-SNAPSHOT: : [INFO] Transforming 'Apache Empire-db Parent'... [INFO] Updating empire-db to 2.0.5-incubating ...
You will be asked about the release versions. Make sure you enter a correct tag: apache-empire-db-(version)-incubating-rc(nr). Once the release vote passes we can then copy this -rcX tag to the final version tag.
INFO: If during this prepare you get some subversion related errors, try to do an "svn update" and valling "mvn release:prepare" again. This will then continue the release preparation from where it stopped. You might have to do this multiple times!
If anything goes wrong during the release you can do a rollback:
>mvn5 release:rollback
Perform the release
This step will upload the artifacts the the staging repository
>mvn5 release:perform
Close the staging repository
Go to: https://repository.apache.org and log in
Follow the steps as described on http://maven.apache.org/developers/release/releasing.html (Close the staging repository)
Create the distribution
Start with checking out the tag and then start the release script
>svn checkout https://svn.apache.org/repos/asf/incubator/empire-db/tags/apache-empire-db-2.0.5-incubating-rc3 ... >./release.sh ...
The script will first ask your GPG passphrase and then generate the distribution and the rat report.
Now upload the generated files to your apache personal directory.
