I'm using Maven 3.0.3 with Git. I use an integration tool (Bamboo) to check out a branch of code from Git into a directory. The tool then uses Maven run the standard build lifecycle (compile, test, deploy). What I want is that if my Maven deploy task succeeds, I want to tag the version of my code that is checked out in Git. How can I do this from Maven? Any sample configurations you can provide are greatly appreciated.

Use Maven SCM plugin. See tag functionality in advanced features, which should be relevant.

Now, git support doesn't come out of the box, so you'll need a dependency to maven-scm-provider-gitexe. Also, to overcome plexus exception issue, you'll also need to add a dependency to a later version of plexus.

This is what worked for me:

<project>
    <scm>
      <connection>scm:git:https://username@github.com/my-project.git</connection>
      <developerConnection>scm:git:https://username@github.com/my-project.git</developerConnection>
    </scm>
    <!-- snip -->
    <build>
      <plugins>
       <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-scm-plugin</artifactId>
         <dependencies>
            <dependency>
               <groupId>org.codehaus.plexus</groupId>
               <artifactId>plexus-utils</artifactId>
               <version>2.1</version>
            </dependency>
            <dependency>
               <groupId>org.apache.maven.scm</groupId>
               <artifactId>maven-scm-provider-gitexe</artifactId>
               <version>1.2</version>
           </dependency>
         </dependencies>
        <version>1.0</version>
        <configuration>
          <tag>test</tag>
          <connectionType>connection</connectionType>
        </configuration>
        <executions>
          <execution>
          <id>tag</id>
          <phase>deploy</phase>
          <goals>
            <goal>tag</goal>
          </goals>
          </execution>
        </executions>
       </plugin>
     </plugins>
    </build>
    <!-- snip -->
</project>

  • COol, this does what I want, although when I run it back-to-back times, I get a "[ERROR] fatal: tag 'qa_release' already exists" error on the second run. I may have to open this as another question. – Dave Jan 18 '12 at 14:36
  • yes, you'll need something dynamic (a property) for the tag name, in this example it's static. – eis Jan 18 '12 at 15:33
  • if the latest tag can be given as a command line parameter, you can just use ${parameter.version} and run maven with -Dparameter.version=v1.2 which would be then used. If autogeneration by maven plugin is needed, some additional logic is required. – eis Jan 18 '12 at 16:06
  • `${project.version}` is reasonable as tag name. – Nowaker Jan 22 '12 at 02:27

maven-release-plugin needs only to declare the scm:

<scm>
    <url>https://github.com/username/repoName</url>
    <connection>scm:git:git://github.com/username/repoName.git</connection>
    <developerConnection>scm:git:git@github.com:username/repoName.git</developerConnection>
    <tag>HEAD</tag>
</scm>

generate git ssh keys

https://help.github.com/articles/generating-ssh-keys/

and run mvn release:prepare

The maven-release-plugin can do this for you -- see an example here: http://maven.apache.org/plugins/maven-release-plugin/examples/prepare-release.html

I recommend the small open source project I'm part of -it's called Quicktag and works with couple of VCSes - https://code.google.com/p/quicktag-maven-plugin. Add the plugin and it will generate Java class with static fields that contain build information.
