I want to diff a war file but IDEA takes too long.
An alternative would be to do something with external tools.
e.g. list the contents to a temporary file, sort the file, get the previous version from version control, list the contents of that and sort it then launch IDEA diff.
I can do the listing and sorting etc from the command line.
How do I wrap this as an external tool and then launch IDEA diff on the two files?
Ideally after it is finished I would delete the two files too.
Is that possible or should I just redirect to thte temp dir and let the OS delete them?
