This may be somewhat obscure but I ve been happily using Eclipse + Perfoce/P4WSAD for over a year now and have thus far been unable to figure this out myself. I often start a build and let it run in the background while I continue to edit source files. The problem occurs when I try to edit a file that is not checked out from perforce. In this case, eclipse pops up a modal dialog box that forces me to choose between either canceling the build or canceling the check-out operation. So usually I just cancel the build, check out the file, and start the build up again, but this is very time consuming. Is it possible to get eclipse to allow check-outs during builds?
If I have a *java file open, I can right click on the source, scroll down to "Show In (Alt-Shift-W)", and select Navigator. If I have an *xml, *jsp, or pretty much anything besides a Java source ...
