Hi all,
I want to listen to changes in files in a folder outside the Eclipse
Workspace, so that eacht time a IResourceChangeListener would be notified.
I read the trick should be somehow to create a link to the Folder with
IFolder, but how can I do it? Something like:
IFolder folder = ...?
Or is there a better way to listen to changes in the file system?
Thanks for any help in advance,
Georg

Thank you Alex,
that helped me to go on, but I´m still struggling. Following some
snippets from the doc on "Linked Resources", I tried the following:
<...>
IWorkspace workspace = ResourcesPlugin.getWorkspace();
IPathVariableManager pathMan = workspace.getPathVariableManager();
String name = "TEMP";
IPath value = new Path( "I:/Temp" );
pathMan.setValue( name, value );
IProject project =
workspace.getRoot().getProject("sianit-rich-client-library");
IFolder link = project.getFolder( "Link" );
IPath location = new Path( "TEMP/SianitUpdateFolder/" );
link.createLink( location, IResource.ALLOW_MISSING_LOCAL, null );
<...>
which throws an exception in the last line (createlink()):
org.eclipse.core.internal.resources.ResourceException:
Cannot create linked resource /sianit-rich-client-library/Link.
probably because the parent of the resource (=the project) is not
accessible (!?).
I´m not sure what that should tell me and how to proceed.
Any hint would be greatly apreciated,
Georg

Normally, eclipse will auto-refresh files when they're accessed e.g. switching to an editor with a file's contents) but you may want to perform manual refreshes (IFolder.refresh(DEPTH_ZERO) or some such -- or DEPTH_ONE or DEPTH_INFINITE to recurse) periodically if they're going to be changed outside of your control.
