error when installing ObjectAid on eclipse

Question

I am trying to install Objectaid for Eclipse Juno 4.2.1. I did all steps found on the Installation from ObjectAid Documentation but still having this error:

An error occurred while installing the items
session context was:(profile=profile,    phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null -->     [R]com.objectaid.uml 1.1.5, action=).
Failed to prepare partial IU: [R]com.objectaid.uml 1.1.5.

I've done Help > Install New Software > Available Software Site and then remove ObjetAid UML Explorer but it didn't work. So I am wondering if there is another thing I can do to achieve the installation?

Answer 1

I was experiencing the same problem on 4.3.2 (Eclipse Kepler).

An error occurred while installing the items session context was:
(profile=epp.package.standard, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null --> [R]com.objectaid.uml 1.1.6, action=).
Failed to prepare partial IU:
[R]com.objectaid.uml 1.1.6.

So I searched the solution for a couple of hours (while this post was being über garbage collected) and I found the answer:

• I had a broken update of the Eclipse Plataform due to https://bugs.eclipse.org/bugs/show_bug.cgi?id=427148

After successfuly updating the platform, I just repeated the steps above and it worked fine.
