这个问题，我用了一下午的时间，在网上搜索各种解决方法都没有解决，最后我同事一句话就给解决了！好了，闲话少说，直接贴问题和解决方法
问题:
ant debug失败，失败信息如下：
BUILD FAILED
/Users/XXX/Documents/Android/Developer/adt-bundle-mac-x86_64-20140702/sdk/tools/ant/build.xml:601: The following error occurred while executing this line:
/Users/XXX/Documents/Android/Developer/adt-bundle-mac-x86_64-20140702/sdk/tools/ant/build.xml:653: The following error occurred while executing this line:
/Users/XXX/Documents/Android/Developer/adt-bundle-mac-x86_64-20140702/sdk/tools/ant/build.xml:698: null returned: 1
解决方法，找到返回BUILD FAILED的最后一行（我的是最后一行，也许不一定）
[echo] Handling Resources...
[aapt] Generating resource IDs...
[aapt] invalid resource directory name: /Users/XXX/Documents/Universal_multi_resolution/projects/cog_universal/proj.android/libs/KongregateSDKLib/bin/res/crunch

就是红色的那行,找到这个路径下的文件夹crunch，直接删除，OK！
