Hi,

When I run this code:

[snip]
IWorkspaceRoot wsRoot = ResourcesPlugin.getWorkspace().getRoot();
IProject project = wsRoot.getProject( "p" );
project.create( null );
project.open( null );

IFolder folder = project.getFolder( "f" );
folder.createLink( new Path( "/tmp/f/" ), IResource.ALLOW_MISSING_LOCAL,
null );

System.out.println( folder.getLocation() );
System.out.println( folder.getRawLocation() );
System.out.println( folder.getLocationURI() );
[snap]

I'm getting:

[snip]
/private/tmp/f
/private/tmp/f
file:/private/tmp/f
[snap]

Which is a bit surprising: where does the 'private' come from? Am I
missing something? How can I get to the correct local path of the linked
folder?

I'm on Mac (OS X 10.5.2) using Eclipse 3.3.2.

Thanks for any help && ciao,
Leif

Are you certain that the project is not located in the directory named
/private ?

Yes, the project is in /Users/leif/workspaces/junit-workspace/ (I'm
running the code out of a PDE JUnit test.)

And even if it was: the location should be the actual location on the file
system, i.e. /tmp/f/, not the location of the project plus the folder's
path. In order words, I'd expect the result to be /tmp/f/ and not
/Users/leif/workspaces/junit-workspace/p/f/

(Btw: I've just done a quick check with Eclipse 3.2.2 on Windows, and it
seems to be ok there.)

Thanks && ciao,
Leif

Hi again,

I did some research and it seems /tmp/ on Macs generally is symlinked to
/private/tmp/, along with other standard unix folders. So Eclipse must
resolve the symlink at some point, and when getting the location we end up
with the resolved path. (I can live with that for my immediate purpose,
although I'm somewhat unhappy with an asymmetric behaviour like this -
setting some path and then directly asking for it should return the same
path again, I would expect.)

Sorry for the noise,
Thanks && ciao,
Leif
