Maven release: next development version in batch mode

Question

I have configured a Jenkins job to release my maven project automatically. This is done by using the following: mvn --batch-mode clean release:prepare release:perform

Answer 1

You can use a custom groovy script to automatically provide maven-release-plugin with the releaseVersion and developmentVersion. Then the maven command would look somwthing like:

mvn clean release:clean release:prepare release:perform -DreleaseVersion=${releaseVersion} -DdevelopmentVersion=${developmentVersion}

Follow the steps in this answer and change the part of the groovy script to suite your use-cases (for example this part):

def newFixVersion = 0;
if (hasSnapshotPart) {  
    newMinorRelVersion = minorVersion;  
    newMinorDevVersion = minorVersion + 1;  
} else {  
    //TODO: either throw an exception here or change the newMinorRelVersion newMinorDevVersion appropriately to suite your use-cases: 
        //throw new IllegalArgumentException("The pom at location " + POM_LOCATION + " contains the version " + projectVersion + " which is not a snapshot version (missing " + SNAPSHOT_PART + "). This is a released version and nothing should happen to it!");  
}
