Re: [tycho-user] [nexus-user] how to get eclipse repos fixed?

I don't believe it is required by any project of ours. The proof is that when I removed the eclipse_release_staging repository, the build finally worked. So I believe it is a transitive dependency pulled in by tycho. We are using tycho 0.17, however, not the latest.

thanks for checking, how did you do it? is there an eclipse tool that allows one to browse p2 repositories (I don't normally use eclipse).

is it possible that this is a bug in the nexus-p2-repository plugin?
I have noticed that the nexus p2 composite repositories do not always work as one would expect; I have had to shut down nexus, remove the composite p2 repo, and restart it when changing the member repositories in order to force it to rebuild the composite {artifact,content}.xml files.

seems like your tool is a good start.. ;)

thanks for your help..
