Eclipse(Indigo) launch failed after google app engine plugin install

Question

After installing the google app engine plugin, eclipse failed to launch. Following is the error statement i got

Job found still running after platform shutdown. Jobs should be canceled by the plugin that scheduled them during shutdown: org.eclipse.ui.internal.ide.IDEWorkbenchActivityHelper$4

I am using eclipse on Linux(Fedora 16).

Can someone kindly help me in resolving this issue?

Thanks

Answer 1

Problem Solved.

The problem is with

org.eclipse.mylyn.tasks.ui_3.6.2.v20110826-0100.jar

Removed it and eclipse is working.

Answer 2

The location is /opt/eclipse/plugins. I am still getting this error after deleting jar. I am using Eclipse Indigo and using ubuntu 12.04. I think there is some other problem for it.

Answer 3

On Mac the jars are located e.g. here (I am running both indigo and juno)

/Applications/eclipse/plugins/org.eclipse.mylyn.tasks.ui_3.8.1.v20120725-0100.jar
/Applications/eclipse/plugins/org.eclipse.mylyn.tasks.ui_3.8.2.v20120916-1200.jar
/Applications/eclipse_indigo/plugins /org.eclipse.mylyn.tasks.ui_3.6.5.v20120215-0100.jar
/Applications/eclipse_indigo/plugins/org.eclipse.mylyn.tasks.ui_3.8.2.v20120916-1200.jar

I ended up following http://expertdevelopers.blogspot.com/2011/07/eclipse-troubleshooting.html which suggest to remove the files. And since I did not understand which files I ended up removing: rm //.metadata/.plugins/org.eclipse.core.resources/.root/.indexes/*
