gradle - Gradle无法通过代理从HTTPS下载插件

Question

我一直在努力获取下载一个来自HTTPS URL的插件的机会，并且无法终生弄清自己在做什么错。根据我在互联网上阅读的内容，通常可以通过设置一个代理(我拥有的代理)来解决此问题，并且在调试日志中，gradle似乎正在使用它。我还尝试过手动将调试日志中所有URL列出的证书添加到我的cacerts文件中，但无济于事。

调试日志-从gradle为springboot插件执行的最后一次重定向开始-如下所示:

我可以通过浏览器下载该文件，该浏览器也使用代理，因此应该可以。这是与Java 1.8.0_71-b15和gradle 3.4一起使用的。

我还从没有代理服务器(也没有为gradle配置代理服务器)的网络上的同一台计算机上尝试了相同的命令，并最终出现了相同的错误，因此这似乎是我的环境而不是代理服务器。

任何想法可能在这里发生什么？

我没有根，这帮助了我
