Support using ${revision} as the project version

[Froodulous]

As of version 3.5, maven supports using the ${revision} placeholder as the version of your project. This is useful in a multi-module project where I want to have a consistent version between all of the modules in the project and have some dependency management for the modules' versions.

Currently this gitflow plugin does not work with this approach - it is unable to parse the version from the pom when starting a release.

I can use the maven flatten plugin to flatten the pom before starting a release. This provides the release plugin with a proper version number and it can start the release, but it is not able to update the "revision" property in the pom to match the release version.

Is there any way to update the gitflow plugin to support this approach?

So you have revision property in your pom and you want to update it after the release, correct?

[Froodulous]

As an example of what I am trying to do, see how Spring Boot stores the version of the project in the revision property here: https://github.com/spring-projects/spring-boot/blob/master/pom.xml.

Rather than updating the revision property after the release, I would like to update it during the release instead of changing the project version directly.

@Froodulous That is clear. The question is: Do you want to change revision property in pom file?
Suppose you have in the pom <revision>1.2.0</revision>, and you execute mvn gitflow:release -Drevision=1.3.0. Do you want to update <revision> in pom to 1.3.0 in production branch and to 1.3.1-SNAPSHOT in development branch?

[Froodulous]

That would be ideal, yes.

+1 for this issue. versions-maven-plugin and tycho-versions-plugin support this feature

[limkinZero]

+1 In spring boot starters kind projects this feature help to manage the version correctly

@Froodulous Steps to support revision in version:

1. Use flatten plugin Since 1.14.0 this is not needed anymore.
2. Set skipUpdateVersion to true
3. Set versionProperty to revision

Should work. :)

@Froodulous @lukelalo @limkinZero 1.13.0 is released. Give it a try.

@aleksandr-m Sorry for the delay replying to this. It works great for me. Thanks a lot for the update.
