Getting IResource from sourcepath entries [message #182049]

Hi,

I need to get corresponding IFolder for each project sourcepath entries.

// variable declarations
IProject project;
IJavaProject javaProject;

IClasspathEntry [] entries=javaProject.getResolvedClasspath(true);

for (int i = 0; i < entries.length; i++) {
IClasspathEntry entry=entries[i];
if ( entry.getEntryKind() == IClasspathEntry.CPE_SOURCE ) {
IPath path=entry.getPath();
IFolder folder=project.getWorkspace().getRoot().getFolder(path);
}
}

Problem is that it doesn't work if
1) Path is absolute, containing device letters( e.g. c:/projects/test )
2) If path points to project root dir
3) If project sourcepath isn't under eclipse's workspace dir

I tried also with javaProject.getPackageFragmentRoots()
but still same problems ...

So how to get *IFolder* from *absolute* IPath?

thanks

1) The path of a source classpath entry must be an absolute
workspace-relative path (see JavaCore#newSourceEntry). "c:/projects/test"
indicates an absolute file system relative path.
2) If the path points to the project, then no corresponding IFolder exists.
You should use getProject(String) in this case:
IContainer container = path.segmentCount() == 1 ?
root.getProject(path.segment(0)) : root.getFolder(path);
3) I'm not sure to understand what you mean here. Even if the location of
the project isn't in the workspace directory, you can still get an IResource
for it.

If you want to use IPackageFragmentRoots, see IJavaElement#getResource().
