When I updated to eclipse 3.2 I found a new irritating feature:
The first time when selecting the Run As-> Ant buildâ€¦ on any of the ant tasks (targets) you have in your build.xml file, you get a window called â€œmodify attributes and launch.â€
After that any time you try to run an ant task (with or without the buildâ€¦) you get an annoying â€œAnt Configuration Selectionâ€ window that makes the ant running process a click longer.
From the top menu select run->External Tools-> External Toolsâ€¦ which will bring you to â€œcreate, manage, and run configurationsâ€ window, there delete all the pre-defined tasks under ant build (on the left bar of the window) and click â€œcloseâ€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.
