cocos打包时提示
发布项目成功

Running command: upgrade
Current version 'cocos2d-x-3.4' is same with target version 'cocos2d-x-3.4'. It's NOT necessary to upgrade project.

Running command: compile
Building mode: debug
ANT_ROOT not defined. Please define it in your environment
项目打包失败
解决途径：将“C:\Program Files\Java\jdk1.6.0_16\lib”目录下的tools.jar文件拷贝到“C:\Program Files\Java\jre6\lib”目录下，重新运行命令ant，运行正常，问题解决。
在cmd命令中：输入ant，如果输出： Buildfile:build.xml does not exist!
正常，重启
===========================================
好吧，最后是cocosstudio的 视图->偏好 里面设置目录就能解决
白花了一天工夫
