Maven release plugin scmReleaseCommitComment parameter

Question

I am using maven release plugin for automated releases from Jenkins without any Jenkins-plugins. Release commit, tag and development commit are created in Git and released project is deployed to Nexus.

What I try to achieve is to change the release commit message. As of release plugin documentation there is an option scmReleaseCommitComment, which is per default @{prefix} prepare release @{releaseLabel}. Maven command look like following and all variables are non empty values.

mvn -f ${projectpath}pom.xml release:clean release:prepare release:perform -DreleaseVersion=${RELEASE_VERSION} -DdevelopmentVersion=${DEVELOPMENT_VERSION}-SNAPSHOT -Dtag=v${RELEASE_VERSION} -DscmReleaseCommitComment=${RELEASE_COMMENT}

Adding scmReleaseCommitComment does no effect and commits are still done with default message. What am I missing here?

That feature was introduced in version 3.0.0-M1 of the maven-release-plugin. You can set it to the latest version in the <plugins> section of your pom.xml, as in the example bellow:

<plugins>
  [...]
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-release-plugin</artifactId>
    <version>3.0.0-M5</version>
  </plugin>
  [...]
</plugins>

Not that you can set the scmReleaseCommitComment in the command line as you showed in your question, using mvn ... release:perform ...-DscmReleaseCommitComment=${MY_RELEASE_COMMENT}, or you can set it in pom.xml:

<plugins>
  [...]
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-release-plugin</artifactId>
    <version>3.0.0-M5</version>
    <configuration>
      <scmReleaseCommitComment>@{prefix} my comment @{releaseLabel}</scmReleaseCommitComment>
    </configuration>
  </plugin>
  [...]
</plugins>
