Android 编译报Run with --stacktrace option to get the stack trace

Android开发在编译过程中经常会报类似如下的错误，突如其来经常会让我们不知所措。这时候最需要的就是静下心来，照着报错的提示排查问题。

Run with –stacktrace option to get the stack trace. Run with –info or –debug option to get more log output. Run with –scan to get full insights.这句话是重点，但是说得不明不白的也不知道要怎么操作。

其实很简单，首先在Android Studio找到Terminal控制台（这个其实和CMD命令行控制台是一样的）

然后在控制台中输入如下指令，就可以重新编译debug版本，且带参数–stacktrace编译，如果编译失败会有失败的路径信息。

gradlew compileDebug --stacktrace

或者–info和–debug参数也用上会打印更多的log信息。

gradlew compileDebug --stacktrace --info --debug
