Using JGitVer in a tycho pomless build

Question

I would like to use the jgitver maven plugin to automatic define the version of eclipse plugins, features, repository that are built with tycho in pomless mode.

The version management of this 3 plugins are:

• jgitver computes a version depending on git tree and tags, create a logical copy of pom, set the new version and associate the new pom to the current plugin in the maven reactor.
• For tycho, version are defined in pom and in manifest.mf or feature.xml files. A version consistency check is performed.
• When the pom is not defined, pomless maven generates a temporary pom file named .polyglot.build.properties using versions defined in manifest or feature file. The input path are defined here and depends on PolyglotModelUtil.

The easier way would be a Jgitver evolution to locally update the feature.xml and manifest.MF. It would be a bad idea because a local file would be modified that is not compliant with the plugin philosophy.

A better way would be a Jgitver evolution to generate temporary feature.xml and manifest.MF files that would have been updated with the computed version. Then tycho and tycho-pomless should be forced to use them.

It seems to be possible if i succeed in setting a new ModelProcessor.LOCATION option

Do you think it's an effective way to solve this compatibility problem? Do you see an alternative?

Thanks for your help.

You could also use directly the jgitver library to participate into your build environment ; it is a pure java library. The library is the base of both the maven and gradle plugins.
