如何使用从浏览器下载的 pom 文件更新 Android Studio？

Question

我收到了旧的“无法解析 com.android.support...”错误消息。现在我确定它是来自 Android Studio 的网络 pr 代理问题，但我可以从浏览器访问 https://dl.google.com/dl/android/maven2/com/android/support/constraint/constraint-layout/1.1.0-beta4/constraint-layout-1.1.0-beta4.pom 并直接下载它......但是在这种情况下如何使用这个 pom 手动更新 Android Studio？

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'.

Answer 1

这让我发疯了，所以希望我的回答可以帮助其他人：

1. 粘贴这是您的 chrome 浏览器： https://dl.google.com/dl/android/maven2/com/android/support/constraint/constraint-layout/1.1.0-beta4/

您将收到 404 错误，但您仍然可以下载证书（开发者工具 > 安全 > 查看证书 > 拖到您的桌面）

1. 删除您当前的 google 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

1. 将刚刚下载的新证书添加到内置 JRE 的 Android Studio 中：

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
