Answer 1

只需从testCompile 'junit:junit:x.xx'文件中删除build.gradle，它就可以正常使用。

如果你想要junit，那么你可能需要添加存储库url。因为android studio可能没有junit库。

android{
    repositories {
    jcenter()
    maven { url "https://www.jitpack.io" }
    mavenCentral()
}

Answer 2

确保您已连接到互联网。

如果你住在像伊朗这样的国家，你应该使用VPN并重新同步你的项目。

Answer 3

通过删除依赖项区域（位于页面底部）的应用程序级别gradle文件中的testCompile 'junit:junit:4.12'来实现它的工作
