Plug-in org.maven.ide.eclipse.jdt was unable to load class org.maven.ide.eclipse.jdt.internal.JDTCompilationParticipant.

I had a previous project which I try to open Eclipse, But it doesnt show any braches such as src/java or src/test,pom.xml.
Can anybody explain me what to do now.

Stack Trace:-

org.eclipse.core.runtime.internal.adaptor.EclipseLazyStarter$TerminatingClassNotFoundException: An error occurred while automatically activating bundle org.maven.ide.eclipse.jdt (737).

muddu_shafi ,
JDT is not certified to run with MyEclipse. That could be the reason you are running into this issue.
