title: Sencha CMD build process applied to an existing ExtJs 4.1 app
body: <p>I am trying to retrofit sencha CMD's build environment to an existing EXTjs 4.1 app. All the coding conventions mentioned in <a href="http://docs.sencha.com/ext-js/4-1/#!/guide/command_code" rel="nofollow">http://docs.sencha.com/ext-js/4-1/#!/guide/command_code</a> are followed. However I get stuck during the compile stage with a <code>java.lang.OutOfMemoryError: GC overhead limit exceeded</code> error.</p>
  
  <p>I am suspecting it could be a circular dependency but cannot be sure. Has anyone tried to use sencha CMD on an existing Ext app? 
  Also can you tell me how to increase the memory used by Ant to run the build process?</p>
  
  <p>Any hints or pointers to  more information are much appreciated</p>
  
  <p>thanks</p>
