How to create file in the workspace? [message #296300]

I have troubles creating files in a folder of a workspace project.
Here's what I do:

assert project.exists() && project.isOpen();
IFolder folder = project.getFolder("myfolder");
assert folder.exists();
IFile file = folder.getFile("myfile");
assert !file.exists();
file.create(stream, false, monitor);
assert file.exists();

IFile.create fails with a ResourceException telling me that:

"Resource /myproject/myfolder already exists."

So #create fails because the target folder exists, but I intended to
create a file in there... any hints what I'm doing wrong?

Thanks,
M

You could always try specifying the 'force' flag to force it to create the file.

It's also possible that you've just created the IFolder from previous uses, and because the actual creation happens in a WorkspaceRunnable, that it hasn't fully commited the changes whilst the thread running. That's the only thing that I can think of, though.

Hi!

Thanks for your answer. I tried to set the 'force' flag to true, but
#create still fails with the same exception. The second potential issue
doesn't apply either because both project and folder were created in a
previous run of the application.

Any other ideas?

Ok, got it now. Problem was that the string passed to IFolder.getFile
was empty. The error message is quite confusing imho...

They can be caused because they're out of sync with the file system. Try doing a folder.refreshLocal(IResource.DEPTH_ONE,null) first of all (or even project.refreshLocal(IResource.DEPTH_ONE,null)) to check that the state of the workspace is up to date with the folder location. It may be that the file exists on disk, but that the workspace doesn't know about it yet.
