For a while now, running `ant` in the flex sdk root fails with this message: "modules\compiler\build.xml:171: Warning: Could not find file C:\Users\user\workspace\flex-sdk\in\flex-tool-api.jar to copy." I then tried running `ant frameworks-rsls`, which then gives me "Error: Unable to access jarfile C:\Users\user\workspace\flex-sdk\lib\optimizer.jar". FYI `ant -f installer.xml` runs just fine.
This is probably a silly thing I'm (not) doing, but I couldn't figure out what. Any ideas?
