Error installing ObjectAid in eclipse LUNA

Question

I have an eclipse LUNA and I'm trying to set an ObjectAid to build 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 am I getting this error and how to overcome it?

thanks

Answer 1

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

The following steps helped me:

• Open "Eclipse Settings" and find "Install New Software."
• Add http://download.eclipse.org/eclipse/updates/3.7 and try installing the plugin again.

Answer 2

This should be fixed in ObjectAid 1.1.8. There was a problem with some Eclipse distributions. They used some older JUnit packages that were packaged than expected by the installer.
