Running External Apps on save in Eclipse

eclipse, eclipse-plugin, unison

Solution

You can setup it to be run on every build. Any external tool can be run on every build, just open project's preferences, go to Builders page, click “New…”.

Problem

Since we cannot setup Eclipse's RSE to use at the tool for remote editing, I have installed Unison. But how can I get Eclipse to automatically run unison on every file save? Is there an eclipse plugin available for this? TIA
