[tycho-user] Tycho versions plugin with aggregator pom

[Lutz Wrage <lutz.wrage@xxxxxxxxx>]

I am trying to figure out how to use the tycho versions plugin to set a new version in a project that uses aggregator poms. An example would be https://github.com/vogellacompany/com.vogella.tychobook.git

This project has an aggregator pom in the repository's root directory which references another aggregator pom in com.vogella.tycho.aggregator. The parent pom is in com.vogella.tycho.parent

When I call mvn org.eclipse.tycho:tycho-versions-plugin:set-version -DnewVersion=1.0.1-SNAPSHOT in the project root directory or com.vogella.tycho.aggregator only the pom.xml there is updated.

If I add the artifact ID of the parent pom (-Dartifacts=com.vogella.tycho.parent) I get an error:
[ERROR] Failed to execute goal org.eclipse.tycho:tycho-versions-plugin:0.23.0:set-version (default-cli) on project com.vogella.tycho.main: Could not set version: Project with artifactId=com.vogella.tycho.parent cound not be found -> [Help 1]

Is this supported at all? And if yes, where do I invoke the mvn command and which parameters do I need?

Thanks!
