Answer 1

The simple solution to set the version to a particular value via versions-maven-plugin

mvn versions:set -DnewVersions=0.0.1

If you like to increment it. This could be achieved by using by build-helper-maven-pugin like the following:

mvn build-helper:parse-version versions:set \
     -DnewVersion=\${parsedVersion.nextMajorVersion}.0.0 \
     versions:commit

or if you like to increment the minor version:

mvn build-helper:parse-version versions:set \
 -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.nextMinorVersion}.0 \
 versions:commit

or if you like to increment the patch version:

mvn build-helper:parse-version versions:set \
 -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.minorVersion}.\${parsedVersion.nextIncrementalVersion} \
 versions:commit

You need to pay attention to quoting which is needed on Windows/Linux.

or you can use maven-release-plugin which will increment the current version to the next one by just calling:

mvn -B release:update-versions

Or you you the maven-release-plugin via the usual release process by mvn release:prepare release:perform which by default increments the version also.
