Eclipse Mars support

[renataogarcia]

Project configurators are not working on Mars Release Candidate 3 (4.5.0RC3), m2e 1.6.0.20150526.

I can confirm the plugin has been installed. I've tried 0.8 and building master(0.9):

I see no errors in Eclipse log and the m2e log. The plugin doesn't seem to be picked up (Full Update Project log output):

This same project is working on Luna Luna Service Release 2 (4.4.2)/m2e 1.5.2.20150413-2215 and m2e 1.6.0.20150526 as well.

Not sure if this is relevant but:
Luna - org.sonatype.m2e.mavenarchiver.feature (0.16.0.201401211452-signed-20140310144306)
Mars - org.sonatype.m2e.mavenarchiver.feature (0.17.0.201502101659-signed-20150525172209)

Generally, m2e-tycho works with latest eclipse and m2e, so there must be something special about your project or environment. I suspect there is an incompatibility with one of the other eclipse plugins you have install. I recommend setting up simple standalone project first, than gradually add features to see at which point it stops working. Once you know what triggers the problem, we can decide what to do about it.

Thanks for the quick reply! I tried reinstalling everything from scratch into a new workspace and it worked. I've pointed the new installation to the old workspace and it also worked. Not sure what went different this time though. Sorry about the noise!
