Hi Alex, I do have a GOOG_HOME in my environment variable, and it's set to something like this: E:\DevareaLocal\ApacheFlexJSFrameworkSource\closure-library-master
The framework source folder structure looks like this: <http://apache-flex-development.2333347.n4.nabble.com/file/n60731/Untitled.png> This structure used to work gracefully for my compilation until few days back. I also tried running this command inside 'flex-asjs' folder as you suggested, which seems completed successfully, ant -f frameworks/downloads.xml subset-goog <http://apache-flex-development.2333347.n4.nabble.com/file/n60731/Untitled2.png> Thing is I badly stuck with this newest SDK now.
