Android Studio报错：Could not download junit.jar

具体错误如下；

Error:A problem occurred configuring project ':app'.

> Could not download junit.jar (junit:junit:4.12)

> Could not get resource 'https://jcenter.bintray.com/junit/junit/4.12/junit-4.12.jar'.

> Could not GET 'https://jcenter.bintray.com/junit/junit/4.12/junit-4.12.jar'.

> Connection to http://localhost:8388 refused

由于下载不下来jar包导致，可以先不用测试依赖

在Gradle文件夹下，找到build.gradle(module app), 将里边的dependences { }中的测试依赖项去掉即可。
