更新 ANDROID_HOME path
从

Update ANDROID_HOME path from

C:/Users/CURRENT_USER/android-sdk/tools/ 

到

C:/Users/CURRENT_USER/android-sdk

这应该可以解决问题
附加工具自动添加到您的 ANDROID_HOME ，因此它搜索graddle里面的tools / tools目录，根本不存在。

This should solve the problem When you build it appends tool automatically to your ANDROID_HOME therefore it searches for graddle inside tools/tools directory which is not present at all.
