Remove Ant Configuration Dialog from Eclipse

	~~==Remove Ant Configuration Dialog from Eclipse==~~

	In Eclipse 3.0 you can launch Ant tasks. This is a great feature. If you don't want to run with the default settings, you can open the configuration settings and add environment variables and add flags. Sometimes I like to add a "-verbose" flag. The problem is after this you are stuck with the configuration dialog popping up each time you launch a target. To stop this, you must delete files in your Eclipse workspace settings. My files are in:

	~~H:\eclipseworkspace\.metadata\.plugins\org.eclipse.debug.core\.launches~~

	~~Then restart Eclipse, and you can now run Ant tasks simply by double clicking on them.~~
