意外的TOP-LEVEL错误：java.lang.outofmemoryexception：java堆空间

Question

我在我的android studio 1.0.2版本中用gradle编译了一个Android应用程序，我收到了这个错误：

Error:Execution failed for task 
    /home/sujata/Downloads/adt-bundle-linux-x86_64-20140702/sdk/build-tools/build-tools-21.1.1/dx --dex --no-optimize --multi-dex --main-dex-list 
  Error Code:

  Output:
