Re: [platform-core-dev] Location of removed projects.

Hi John,
Thank you very much for your advice. You saved me many hours of
experimenting.
Regards,
Thomas Hallgren

I think you'll need to use a combination of PRE_DELETE and
POST_CHANGE. Typically, IResource#getLocation() should return a valid
value after the fact, in a POST_CHANGE event. The main case where
IResource#getLocation() will return null is when the project has been
deleted, at which point we can't make a reasonable guess after
deletion about where that project was located. By listening for
PRE_DELETE, you will capture project deletions, at which point the
project location is still available. So, I would suggest trying
something like this:
In PRE_DELETE, record the location of each project being deleted.
In POST_CHANGE, call IResource#getLocation(). If this returns null,
use the project location recorded in PRE_DELETE, and append the
resource's project-relative path (IResource#getProjectRelativePath()).
IResource#getLocation can also be null if the resource is not stored
in the local file system. In this case, you can use
IResource#getLocationURI to obtain the resource location.
