When I updated to eclipse 3.2 I found a new irritating feature:
The problem:
The first time when selecting the Run As-> Ant build… on any of the ant tasks (targets) you have in your build.xml file, you get a window called “modify attributes and launch.â€
After that any time you try to run an ant task (with or without the build…) you get an annoying “Ant Configuration Selection†window that makes the ant running process a click longer.
The solution:
From the top menu select run->External Tools-> External Tools… which will bring you to “create, manage, and run configurations†window, there delete all the pre-defined tasks under ant build (on the left bar of the window) and click “closeâ€â€¦
I found this workaround here: http://dev.eclipse.org/newslists/news.eclipse.platform/msg20976.html
I hope eclipse will provide a different mechanism that will work around this problem in their next release.
