Recently, and for now reason that I can find, when I open an editor for an ant build.xml file, ALL of the ant tasks are reported as errors with the message "cannot resolve symbol X".
All of the intelli-sense within the editor still works. The more annoying issue is the fact that every time I move the mouse, I get tooltips about the errors and can't click anywhere until the tooltip auto-hides.
I have checked the logs, no errors. I have checked the knowledge base and forums, could not find anything fully relevant. Other members of my team are not having this problem.
This could be reported as a couple of bugs:
1) The fact that it is happening in the first place
2) IDEA is not reporting any information on how to fix the problem or what is actually going wrong
I am attaching a small screenshot for reference.
