Eclipse missing action Set

Question

I have a problem while opening Eclipse. In the error log it says:

unable to find action set org.eclipse.wb.core.ui.actionset 
       org.eclipse.rse.core.search.searchActionSet
       org.eclipse.rse.core.search.searchActionSet
       org.eclipse.mylyn.doc.actionSet
       org.eclipse.mylyn.context.ui.actionSet

I'm using Eclipse juno(version 4.2) and my ADT is version20 and Java 1.6 Do you have any idea what I am supposed to do?

Answer 1

In general this is a leftover from something you have uninstalled. To get rid of the error, close Eclipse, find the workbench.xml (XML) and workbench.xmi (XMI) files in either the

.metadata\.plugins\org.eclipse.ui.workbench\

or

.metadata\.plugins\org.eclipse.e4.workbench\

directories within your workspace and remove ALL corresponding lines (search for the package name you see in the message).

Answer 2

I think that this can happen when features are removed from Eclipse and a workspace is not properly updated. Create a new workspace, import all your projects, and delete the old workspace.

Answer 3

I went to the run configurations for the RCP app I had (created using EMF) and I checked the radio box under the Run--> configurations... dialog to "Clear workspace" before running. This fixed the issue about the missing ActionSets. I tried to find the references to the missing ActionSets per the above method and that did not fix the bug (there were no references to the missing ActionSets in the workbench.xml or workbench.xmi files. I am using Kepler SR2 on Mac OS X 10.9.2.
