[ JDK VERSION : J2SE 1.5.0 ]

The only way to Cancel a build before it completes is to Terminate the build process from the Runtime window. This is very unintuitive, difficult to find or guess, and does not display graceful exit text in the Output window. You cannot create a toolbar button or a menu item to cancel a build because there is no associated Action.

We need an Action that we can assign to a toolbar button or menu item that will gracefully cancel a build and display the reason the build ended in the Output window after whatever text the build generated up to that point.

This is logged as a defect since a build cancel is as standard a function as the build itself.
