Gradle:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':TestAndroid:compileDebug'.
> Compilation failed; see the compiler error output for details.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
Could not execute build using Gradle installation 'C:\gradle-1.6'.

首先进入命令行
进入项目根目录（grale文件所在目录）
输入命令

gradlew compileDebug --stacktrace

查看错误位置：
