Question

I’m trying to use the maven SCM plugin to commit some files to a git repo during an automated build, the plugin requires a commit message to be set as a system property, I don’t want to have to pass this on the command line (I’m also using the release plugin and this causes issues).

I’ve tried everything I think of to add the message system property via the pom but no luck, here’s a stripped down version of my pom:

                </plugins>
            </build>
        </profile>
    </profiles>
</project>

Adding message via the profile properties seems to work, the files are commited to get and the message appear in the repo but the build fails with this error:

    [ERROR] Provider message:
    [ERROR] The git-commit command failed.
    [ERROR] Command output:
    [ERROR] 
    [INFO] ------------------------------------------------------------------------

    [ERROR] Failed to execute goal org.apache.maven.plugins:maven-scm-plugin:1.8.1:checkin (add-version-to-git) on project: Command failed.The git-commit command failed. -> [Help 1]

Any ideas on what I’m doing wrong?

Try changing the pom.xml to look like this:

...
    <executions>
        <execution>
            <id>add-version-to-git</id>
            <phase>package</phase>
            <goals>
                <goal>add</goal>
                <goal>checkin</goal>
            </goals>
            <configuration>
                <basedir>./</basedir>
                <includes>versions/*</includes>
                <message>[Add Version to git]</message>
            </configuration>
        </execution>
    </executions>
...

Try using message property instead of systemProperties.

Or you could always do this in command line like:

mvn -Dmessage="<commit_log_here>" scm:checkin

as stated here
