Build 20030214 Setup from bug 32040 (prj==src(with custom bin2), default output=bin), observe that 'bin2' is displayed as empty package in package explorer (it should not be visible at all).
The more interesting scenario is: <?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="" excluding="src1/|src2/"/> <classpathentry kind="src" path="src1" output="bin1"/> <classpathentry kind="src" path="src2" output="bin2"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> <classpathentry kind="output" path="bin"/> </classpath> In this case, you have several source folders defined inside the project, which is still acting as its own source folder. The source folders are explicitly excluded from the project BUT not their output folders. The question is why not? Why were the additional source folders added to the exclusion list, but their output folders weren't? This isn't necessary unless the project is acting as a source folder at the same time.
You should never have to add output folders to exclusion filters as output folders should never be visible through the Java model (see IJavaModel.contains (...))
Changed PackageFragmentRoot.computeFolderChildren(...) to check if the folder is visible through the Java model (using contains()). Added regression test JavaProjectTests.testRootGetPackageFragments2()
.java files in 'bin' and 'bin2' should not be indexed either. Fixed IndexAllProject to not walk output folders and added regression test ExclusionPatternTests.testSearchPotentialMatchInOutput()
Verified.
