Bug with installing ObjectAid into eclipse LUNA

问题:

I have eclipse LUNA, and I am trying to install ObjectAid for building UML diagrams. When I try to install it I get the following error:

An error occurred while collecting items to be installed
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Artifact osgi.bundle,org.junit,3.8.2.v3_8_2_v20100427-1100 is a folder but the repository is an archive or remote location.

Why do I get this error, and how to overcome it?

Thanks

I had the same error message during installing e(fx)clipse plugins. Also using Luna.

Following steps helped me:

1. Open the Eclipse Preferences and look for Install New Software
2. Add http://download.eclipse.org/eclipse/updates/3.7 and try to install your plugin again.

This should be fixed in ObjectAid 1.1.8. There was an issue with certain Eclipse distributions. They used some old JUnit bundles which were packaged different than expected by the installer.
