I'm working with Eclipse 4.6.3 and when I open a .java file I got the 2 following errors
The org.eclipse.jdt.ui.javaElementFilters plug-in extension "org.eclipse.buildship.ui.packageexplorer.filter.gradle.subProject" specifies a viewer filter class which does not exist. Plug-in org.eclipse.buildship.ui was unable to load class org.eclipse.buildship.ui.navigator.SubProjectViewerFilter. An error occurred while automatically activating bundle org.eclipse.buildship.ui (73).

The org.eclipse.jdt.ui.javaElementFilters plug-in extension "org.eclipse.buildship.ui.packageexplorer.filter.gradle.buildfolder" specifies a viewer filter class which does not exist. Plug-in org.eclipse.buildship.ui was unable to load class org.eclipse.buildship.ui.navigator.BuildFolderViewerFilter. An error occurred while automatically activating bundle org.eclipse.buildship.ui (73).
These errors are not blocking Eclipse, I can still create/edit/save/delete files.
Does someone know where it comes from ? and how to solve it ?
