I have just upgraded to sencha CMD 4.0.0.0 and started getting this error while building my package.

[ERR] The following error occurred while executing this line:
C:\Nipendo\Dev\WebApplication\packages\n-theme-classic\.sencha\package\build-impl.xml:184: The following error occurred while executing this line:

Is there a workaround, does any body know what is that about??

Answer 1

This error means that compass process choked on something and exited with an error. Try running the build with debug logs:

sencha -debug app build

This will get very verbose but may help you to pinpoint the problem.
