Sencha Cmd v3.0.0.230
Mac OSX 10.6

Took this off the sencha blog post:
Code:
        sencha compile -classpath=ext4/src \
                exclude -namespace Ext.chart and \
                concat -out ext-all-no-charts-dev.js and \
                -option debug:false \
                concat -out ext-all-no-charts-debug.js and \
                concat -yui -out ext-all-no-charts.js
The build includes charts.

One guy says if he excludes "debug" he can make it work, but I had no success.

Has anyone got a no-charts version, can you share the working command?
