将AS更新到3.1.3后，我遇到同样的问题：
I am getting these errors while syncing gradle ： -
错误：无法解析'：app @ debug / compileClasspath'的依赖项：无法解析xxx .
错误：无法解析'：app @ debug / compileClasspath'的依赖项：无法解析xxx .
错误：无法解析'：app @ debugAndroidTest / compileClasspath'的依赖项：无法解析xxx .
错误：无法解析'：app @ releaseUnitTest / compileClasspath'的依赖关系：无法解析xxx .
错误：无法解析'：app @ debugAndroidTest / compileClasspath'的依赖项：无法解析xxx .
Solution for fix this issue ：
1 . 在SDK Manager>外观和行为>系统设置> HTTP代理中检查代理 . 应检查自动检测代理设置 .
2 . 默认设置构建，执行，部署>构建工具> Gradle取消选中脱机工作 .
3 . 在左侧面板中选择Project explorer> Android Check Gradel Scripts目录 . 查找cradle.properties（全局属性）它包含代理添加的属性请注释所有这些属性 .
Try to clean and build.
现在检查所有依赖项解析 .
