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!)
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?).
Ah, I was getting this problem this morning. A search showed that it was possibly related to JGit/Egit. After updating the EGit plugin from 0.5 to 0.6, the errors have not returned.
you can make a variable junit or smtg similar your custmized add the junit folder to this varible, give extension of it as junit4.8.1.jar
i tried it works but you have to delete any plugins of junit of version4 if present from plugins folder.
