These two seem to be related, but they are not :
Exclude folders from Eclipse search
Exclude target folder from search results in Eclipse
How can I exclude the target folder (of all projects) when I look for a resource using Ctrl + Shift + R ?
I am packaging using maven and my target folder(s) is recreated all the time. Its cumbersome to mark the folders as derived after every single build and I have about 30 sub/projects. I am on eclipse kepler.
