我无法在 Android Studio 中构建项目，并且收到以下错误。

Gradle 同步失败。
无法获取“https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.1.3/gradle-3.1.3.pom” '
无法获取“https://jcenter.bintray.com/com/android/tools/build/gradle/3.1.3/gradle-3.1.3.pom” '

这是我已经尝试过的:

我已将以下内容更新到最新的可用版本:

Android SDK 构建工具
Android SDK 平台工具

最佳答案

我找到了解决方案。

问题是我为我的大学代理服务器设置了代理详细信息在 Android Studio 中访问互联网。当这个问题出现时我试过了使用代理在互联网连接上使用代理构建项目，但它没有用。
然后我从 Android Studio 首选项中删除了代理，然后连接到非代理互联网连接，但问题没有消失。
然后我用 Google 搜索了很多并来到这里，但找不到根本原因。
我将 AS 从 3.1.3 更新到 3.2，但问题仍然存在。
最后，我开始在 AS 中寻找隐藏的代理服务器详细信息，在位于 Gradle -> 的 gradle.properties 文件中找到它们资源包“gradle”-> gradle.properties。
删除了此文件中的代理服务器详细信息并运行构建在根据 Android Studio 的建议执行一些包更新后成功完成。

宾果! 😎
