Dependencies 如何使用从浏览器下载的pom文件更新Android studio？

我收到旧的“无法解析com.android.support…”错误消息。现在我确定这是安卓工作室的网络公关代理问题，但我可以从浏览器访问并直接下载…但在这种情况下，我如何使用此pom手动更新安卓工作室

Could not resolve com.android.support.constraint:constraint-layout:1.1.0-beta4.
> Could not get resource 'https://dl.google.com/dl/android/maven2/com/android/support/constraint/constraint-layout/1.1.0-beta4/constraint-layout-1.1.0-beta4.pom'.

这让我发疯，希望我的答案能帮助其他人：

粘贴这是您的chrome浏览器：

您将收到404错误，但仍然可以下载证书（开发者工具>安全>查看证书>拖到桌面）

删除您当前的谷歌别名（我的是*.google.com）

keytool-delete-alias*.google.com-keystore/Applications/Android\Studio.app/Contents/jre/jdk/Contents/Home/jre/lib/security/cacerts-storepass changeit

添加刚下载到Android Studio内置JRE的新证书：

keytool-import-v-trustcacerts-alias.google.com.cer-file/Users/dz5p4d/Downloads/android_certs/.google.com.cer-keystore/Applications/android\Studio.app/Contents/jre/jdk/Contents/Home/jre/lib/security/cacerts-keypass changeit-storepass changeit

来吧，这里没有人有建议吗？？
