Question

Using maven release:prepare simplifies the process of deploying an artifact. It is possible to define the tag with tag tag. The plugin allows to use properties to build a customized tag-name.

But I need a more customized version, which used “_” insteat of points for delimeters in version. e.g. version: 1.0.1.2 => tagname should be 01_01_01 .

If I could access the majorVersion, minorVersion of ${project.version} this would be a solution too. But it seems that they are not available general.

build-helper plugin seems to be no solution since I call release:prepare and therefore any settings by this plugins will be lost.

Any ideas how to achieve this in an easy manner?

Answer 1

The easy way is to always run maven like so

mvn validate release:prepare

Of course if you forget to invoke validate prior to release:prepare your release will be borked… so that’s no good.

The next improvement is to have a profile with defaultGoals

<profile>
  <id>prepare-release</id>
  <build>
    <defaultGoal>validate release:prepare</defaultGoal>
  </build>
</profile>

Then you release by doing the non-standard

mvn -Pprepare-release

The true fix would be to suggest a patch to the maven release plugin to allow regex like replacement in the tagNameFormat configuration parameter.
