Eclipse won't load my workspace... [message #1682613]

Tue, 17 March 2015 16:15

Eclipse User

So I go to load my workspace, and instead of loading my project and my classes it gives me this error:

Plug-in org.eclipse.jdt.ui was unable to load class org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitEditor.

And in my package explorer I get this error:

Plug-in org.eclipse.jdt.ui was unable to load class org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart.

In the Details I get this long list of errors:

org.eclipse.core.runtime.CoreException: Plug-in org.eclipse.jdt.ui was unable to load class org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart.

This ...

Could not read metadata for 'C:\Users\Noobhun\Desktop\SpeciesMod\eclipse\.metadata\.plugins\org.eclipse.core.resources\.root\.indexes\properties.index'. Unexpected version: 0.

... seems to indicate some corruption of the workspace. I'm not sure if calling Eclipse with -clean or such will fix the issue.
The obvious workaround would be to create a new workspace and import your projects into it.
If that's not an acceptable solution for you, please seek help in the platform forum at https://www.eclipse.org/forums/index.php/f/11/ (those indexes are managed by org.eclipse.core.resources).
