Re: [equinox-dev] ClassCastException in LocalMetadataRepository

I think "tycho-users" would be a better list, as the RemoteMetadataRepository is a tycho class:

 org.eclipse.tycho.p2.remote.RemoteMetadataRepositoryManager

But,  I think if you did ask there, you'd learn that Tycho does not support the old-style "site.xml" repositories, which is what the "findbugs" repo is, that you referenced. p2 by itself (or tools that delegate completely to p2, such as b3 aggregator) do handle these old-style sites, by basically "downloading everything" and doing a "conversion to new-style site" on the fly.

You would probably also learn, if you asked on tycho-users, that your options are to a) convince original project (findbugs) to "move up", or b) make your own p2 repo "on the side" from the old-style site, and then in your build point to your new-style site. At least, that's what I learned by doing a web search for "Tycho and site.xml" and finding

http://stackoverflow.com/questions/22628911/how-to-use-a-site-xml-base-update-site-in-a-tycho-build

That stackoverflow answer also points to a URL with an example of one way to accomplish this:

http://wiki.eclipse.org/Tycho/Additional_Tools#publish-features-and-bundles_goal

Hope that helps,

Hello,

I am one of the maintainers of m2e-code-quality [1]. When I add the FindBugs update site [2] as a p2 repository, the build fails [4]. 


Debugging into the problem I found that the problem is LocalMetadataRepository:325 [4]. It's actually RemoteMetadataRepositoryManager not a MetadataRepositoryManager. Therefore resolving the update site fails.

Am I doing something wrong? Or might this be a bug?

Regards,

Arlo
