No schema found for the "org.eclipse.ui.menus" extension point

Question

The eclipse version I have installed is 10.0.1. When I add an extension point "org.eclipse.ui.menus" and when I click right to create a sub menu option, it only shows me a "Generic".

And it says that there are 3 warnings:

No schema found for the "org.eclipse.ui.menus" extension point

How can I solve this problem?

Answer 1

I met the same problem in Eclipse 4.3. It occurred because of the absence of source bundles for eclipse plugins. Resolved it by the following steps:

1. In Eclipse go to Help > Install New Software...
2. Update site: http://download.eclipse.org/eclipse/updates/4.3
3. Choose "Eclipse RCP Target Components" and press Next to install them

Answer 2

For me the solution was to create a fresh workspace, instead of re-using the old eclipse-luna workspace ( during upgrade from eclipse-luna to eclipse-mars )

Answer 3

The schema for this extension is defined in the org.eclipse.ui bundle. Make sure you have added the appended source-bundle of the org.eclipse.ui (org.eclipse.ui.source) bundle in your target-platform. In this bundle the .exsd schema is located that is required to show the extension-specific forms.
