Max Rydahl Andersen updated JBIDE-17268:
----------------------------------------

        Summary: Forge wizards block eclipse UI while executing - need to be stoppable/canceble  (was: Forge wizards block eclipse UI while executing - need to be backgroundable)
    Description: 
Forge wizards currently can block the eclipse UI. Run any non-trivial command and the Eclipse interface will be completely blocked until the forge command is cancelled, which may not be possible if the command is not using a fine-grained progress monitor and checks frequently.

Introducing a threaded command execution would allow the use of {code}commandThread.interrupt(){code}

And should allow both backgrounding of running wizards, but also more reliable cancellation with Forge's proxy support for thread interrupt handling.

Alternative is to:
provide method to cancel progress.
on first try cancel if command is "CanCancel" then use progress monitor cancel, if not use thread.interrupt() that will stop the progress on proxy boundaries.
