Auto build project with ant in Eclipse

Who needs Eclipse if there is a shell?

In Eclipse, go to Project's properties and add a new builder of type ant.

On tab Main provide:

• Build file
• Base Directory
• Desired arguments that will be passed to ant ( -Dproperty=value style)

On tab Targets provide ant tasks for targets Auto Build, After a Clean.

Now you can just change sources and save the source file, 

Eclipse will execute "Auto Build" target right away.
