Hello,
I wrote this method tonight. It finds all the source pacakge fragment
roots of an IJavaProject, and tries to find the one that is the parent
of a supplied IFile.
private boolean isFileInSourceFolder(
IFile file, IJavaProject jp)
throws JavaModelException {
for (IPackageFragmentRoot root : jp.getPackageFragmentRoots()) {
// Only accept source roots.
if (root.getKind() != IPackageFragmentRoot.K_SOURCE) {
continue;
}
IPath rootFullPath = root.getCorrespondingResource().getFullPath();
IPath fileFullPath = file.getFullPath();
if (rootFullPath.isPrefixOf(fileFullPath)) {
return true;
}
}
return false;
}
I imagine there must be an easier way to do this. For example, create an
ICompilationUnit from the IFile, and find its IPackageFragmentRoot, but
I don't know.
Do you have any recommendations?
Thanks, Robert

Ah, I found something slightly better. It doesn't require the
IJavaProject, and it doesn't throw any checked exceptions:
private IPackageFragmentRoot getPackageFragmentRoot(IFile file) {
IJavaElement elem = JavaCore.create(file.getParent());
while (elem != null && !(elem instanceof IPackageFragmentRoot)) {
elem = elem.getParent();
}
return (IPackageFragmentRoot) elem;
}
private boolean isFileInSourceFolder(IFile file) {
return getPackageFragmentRoot(file) != null;
}
Thoughts on this one? I still believe there must be an easy way to get
from any element to its IPFR.
Thanks, Robert

Remy to the rescue:
IJavaElement elem = JavaCore.create(file.getParent());
return (elem == null)
? null
: (IPackageFragmentRoot)
elem.getAncestor(IJavaElement.PACKAGE_FRAGMENT_ROOT);

You might also want to look at IJavaProject.isOnClasspath(IResource
resource);

(1) You can find out the parent of every IResource in the workspace.
(2) Haven't not explored yet, but may be the JDT has an utility method
to determine if an IFolder is a source folder, once you get the parent
of the IFile?
