Christoph Läubrich commented on MNG-8250:
-----------------------------------------
The problem seem to be the return value of
org.eclipse.tycho.build.pomless.ManifestModelParser.ManifestSource.getPath()
... maven seem to use (and validate) it in some ways, e.g.
* if I return the path I get above exception.
* If i return a directory inside it works
* if I return full path I get "The POM found does not belong to the given
directory"
* if I return null (what is allowed) I get "Child subproject null of
/home/christoph/git/laeubi/tycho/tycho-its/projects/reactor.makeBehaviour/pom.xml
does not exist"
> [Maven4] ModelParser#parse is not called for custom model source
