I suggest that C-u C-c C-v C-b invert the meaning of the jde-read-{make,ant}-args flag.
I often want to issue the same build command, but sometimes a different one. So I set jde-read-make-args to t, but now I have to press an extra key in 99% of the build invocations: C-c C-v C-b RET. What do people think? Kai
