【问题描述】：
我是一名计算机科学专业的学生，我正在尝试熟悉构建应用程序以作为暑期爱好。但是，在过去的几天里，当我尝试同步 Gradle 时，它给了我同样的错误，说明
gradle-core.jar 无法下载。
我将在这篇文章的底部发布完整的错误消息。
当然，我确定我不是在离线模式下工作。最重要的是，我强制使用http:// 获取https:// 源。我还在gradle-wrapper.properties 文件中将distributionUrl 的https:// 更改为http://。我尝试了不同的代理，并将build.gradle 文件中的存储库更改为jcenter(), mavenCentral(), and google().
我什至尝试与我的防火墙同步，并且关闭了防病毒软件，但没有任何效果。您将在下面找到我的完整错误消息。

请编辑您的帖子以包含任何相关文件（build.gradle、gradle.properties 等）

@jddahl19 有什么解决办法吗？
-
@ArnoldBrown 我修复了它，但我不太确定如何。我卸载了 Android Studio 并删除了我之前的所有设置。然后我重新安装了 haxm，发现 VT-x 在我的 BIOS 中被禁用，所以我启用了它并重新安装了 Android Studio 并允许它与新的 gradle 设置同步。在所有这些步骤之后，Gradle 开始为我同步，所以我不确定这些事情中的任何一个是否单独解决了我的问题，或者它是否是解决问题的所有东西的集合。试试看吧

@jddahl19 感谢您的回复。我也这样做了，因为我觉得重新安装比发现问题并由于工作紧迫而修复要容易得多。
