Android studio 读取超时错误builder.jar（com.android.tools.build:builder:3.2.1）-flatter-android Studio

我只是想运行我的第一个颤振应用程序

我已经尝试使缓存无效。虽然我的网速很慢，但我已经手动下载了不到一分钟的依赖项。但是我无法手动安装依赖项

我是否可以手动添加此builder-3.2.1依赖项或任何其他解决此问题的方法？如果是，那怎么办？

我也有同样的问题。。我通过升级gradle来修复它。。通过以下步骤：

• 打开gradle wrapper.propatiates（如果您找不到它，请打开gradle>local propatiates，然后单击在android studio中进行编辑您将在那里找到gradle wrapper.propatiates

• 改变分配=https://services.gradle.org/distributions/gradle-4.10.8-all.ziptodistributionUrl=https://services.gradle.org/distributions/gradle-X.X.X-all.zip根据最新的gradle版本

• 然后根据最新的combatable gradle插件版本打开文件>项目结构>项目>android gradle插件版本（将其更改为X.X.X）
