I just found this little trick and thought i'd share ----------------------------------
Sometimes when using eclipse I need to jump to a file. I press CTRL-SHFT-R to pop up the resource. However most of the time I end up editing a copy of the file in a build folder. The solution to this problem is to Right click the troublesome folder, select properties and Click Derived. Now when Jumping to files with CTRL-SHIFT-R you wont edit the bad copy. http://robmayhew.com/eclipse-ignore-folder/
