eclipse: auto build after save

Question

I have an ant script that creates runnable jar and I want it to run each time I make changes in my code and save them. I guess I need some "auto build after save" option in Eclipse. Is there such a thing?

Answer 1

You could declare your script as a builder, and make it run "during auto build".

See the properties of your project: you can add an external program (above) or an an script (below).

If you can export your script as an ant script, like the OP David B did in his answer, it becomes quite easy:

1. Export as an ant script: right-click the project -> export -> runaable jar file, tick "save as ANT script" and finish.
2. Add the ant script as a builder: right-click the project -> properties -> Builders -> new (Ant).
   Paste the path for the ant file, go to "targets" tab and click the "set targets" button next to "auto build".
   Finally, click OK, OK, OK.

Answer 2

Actually, the best solution I found was: right-click the project -> export -> runaable jar file, tick "save as ANT script" and finish. Now right-click the project -> properties -> Builders -> new -> paste the path for the ANT file, go to "targets" tab and click the "set targets" button next to "auto build", OK, OK, OK.
