Using Maven, Git: How do I tag the latest version of my code?

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

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://[email protected]/my-project.git</connection>
      <developerConnection>scm:git:https://[email protected]/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 -->
