Android 错误：（3，17）java:package org.junit不存在-intellij

我最近开始使用IntelliJ构建我的android应用程序项目。我将sherlock库作为一个模块导入，并将依赖项添加到我的项目中。但是，当我尝试重建项目以检查任何错误时，我会得到一行10个错误，如下所示：

类路径中似乎缺少

junit.jar

。添加它，它应该可以工作。

您可以检查插件是否已安装（如果已安装）。只需将其添加到类路径中，您就可以通过选择junit单词，然后按下左侧的黄色灯泡选择“将junit添加到类路径”

在build.gradle中添加以下行来自动完成此操作。解决了此问题

编译'com.android.support.test:runner:0.5'
