Eclipse Galileo - JUnit missing

Question

Build Path > Add Library > JUnit unable to add JUnit3 or JUnit4 components.

I see such message in the .log

!MESSAGE No property tester contributes a property projectPersistentProperty     org.eclipse.team.core.repository to type class org.eclipse.core.internal.resources.Project

Eclipse Galileo installed by root user on Linux. It works well for root and for other users except this JUnit issue.

Why it lost Junit? (I've checked file permissions twice - all readable!)

Answer 1

This seems to be related to bug 239715, triggered by TypeExtensionManager.java, and due to some kind of plugins combination.

Could you check if your org.eclipse.core.expressions/.options file has the line

org.eclipse.core.expressions/debug/TypeExtensionManager=false

This should be enough to make that error message disappear.

That file is <eclipse-SDK-3.5-win32>\eclipse\plugins\org.eclipse.core.expressions_3.4.100.v20090429-1800.jar, and I just checked, it does contains the right option value (with latest Galileo) (are you using an older Galileo RC or Milestone release?).
