How to fix building workspace problem in Zend Studio?
I'm trying to rename project and rename folder of project, however nothing:
Errors occurred during the build. Errors running builder 'JavaScript Validator' on project 'PROJECT'. java.lang.NullPointerException
The bug has been fixed, you can either wait for the new release or apply the patch :
you must go to Project->Properties->Builders then disable ‘Javascript Validator’.
I had similar problem and mine is that the saving workspace process try to write in one of the file and it can't even it is available under .metadata directory.
This is how I did:
Open the .metadata directory and look for that particular file, yours can be different, so change it to read and write for this file then restart eclipse.
It fixed the problem!.
My OS: Ubuntu 10.04 , Eclipse SDK 3.5.2
Hope this help...
