Re: [tycho-user] Generating POMs for pomless build fails for category.xm

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

I fear that tycho-pomgenerator-plugin is of less use today and so it 
might be outdated and is not optimized to run *together* with 
pomless-build, so you should at least disable the pomless extension if 
you like to use poms instead.

If you want to keep your pomless build, you should be able to configure 
what is required in the parent-pom. If you still like to get the 
generated poms form the pomless-build as a starting point, you should be 
able to run the pomlessbuild with

-Dpolyglot.dump.pom=pom.xml
