I've just updated my android development tools to revision 13. This all went smoothly and I can continue to build in eclipse as usual.
However once I try to de a release build with ant my build fails with the message "unknown option: --output".
Further Info: I'm running 32bit Eclipse / Java on 64 bit windows. The issue occurs only when running a build from the command line and the build worked before I updated the sdk from revision 12 to 13.
Here is the relevant output from "ant release"
