android - Gradle Sync问题:连接被拒绝:连接

Question

我不确定是什么原因导致了我的问题。我试图检查gradle.properties，并且文件是干净的。检查了我的驱动程序，如果它们已过时，则不是问题。使用zip文件从头开始安装了Gradle和Studio，因此我认为该项目的构建不正确。我很确定，这是因为我现在住在中国，并且由于防火墙的缘故，gradle无法连接到其服务器。问题有可能是由我的位置引起的吗？

它卡在解析依赖关系的部分。连接被拒绝

所以这是事情。解决问题真的很容易。只需转到文件->设置->构建-> Gradle-> Android Studio->并选中“启用嵌入式Maven存储库”
但!现在又出现另一件事... ERROR: Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.support:appcompat-v7:27.1.1. Show Details Affected Modules: app
