[GREENFOOT-569] Greenfoot 3.0.3 does not build from published source bundle

Greenfoot 3.0.3 cannot be built from the source bundle:

{quote}build-common-jar:

BUILD FAILED /home/davmac/gf303src/greenfoot/build.xml:389: The following error occurred while executing this line: /home/davmac/gf303src/greenfoot/build.xml:403: destination directory "/home/davmac/gf303src/greenfoot/common/Weather/classes" does not exist or is not a directory {quote}

This needs to be fixed ASAP.
