Hi
Is it possible that the git updates has caused my eclipse IDE to stop working properly, or is it something else?
I cannot edit any file in my projects and running eclipse with -clean doesn't help.
I get a pop-up error with:

An error has occurred. See error log for more details.
org/eclipse/jdt/core/IJavaElement

Has anyone else come across this?

Cheers
Bill
