求教cocos2dx3.6用ant打包报错问题,求大神解答

ant: apache-ant-1.9.4-bin
python: python-2.7.9.amd64.msi

在windows7 64位下建立新项目, 执行build_native.py最后打包有如下错误

c:\test\proj.android\build.xml:81: Cannot find c:\adt\sdk"\tools\ant\build.xml imported from c:\test\proj.android\build.xml

import出来的路径多了个一个"号
我把build.xml的路径改成全路径, 错误变成如下:
c:\adt\sdk\tools\ant\build.xml:397: Problem: failed to create task o
r type checkenv
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any / declarations have taken place.

是否ant的版本或者python的版本不匹配?求大神解答
另用Eclipse是成功的

:2:解决了没,!!!!
