Gradle無法通過代理從HTTPS下載插件

我一直在試圖讓gradle下載一個來自HTTPS URL的插件，並且無法爲我的數字生活做出我在做什麼錯誤。從我在互聯網上閱讀的內容來看，這通常是通過設置一個代理來解決的 - 我擁有這個代理，並且從調試日誌中看到gradle似乎正在使用它。我也嘗試手動添加列出調試日誌中的所有URL證書到我的cacerts文件無濟於事。Gradle無法通過代理從HTTPS下載插件

調試日誌 - 由gradle這個對springboot插件進行最後的重定向 - 如下圖所示：

我可以通過我的瀏覽器，它也使用了代理，這樣應該沒下載此文件。這與Java 1.8.0_71-b15和gradle 3.4一樣。

我也嘗試了從同一臺機器在沒有代理的網絡上（也沒有代理配置爲gradle）的相同的命令，並最終出現相同的錯誤，所以它似乎是這樣的東西與我的環境，而不是代理。

任何想法可能會發生什麼？

用'-Djavax.net.debug = all'再試一次，這樣你就可以看到證書鏈上發生了什麼。顯然，瀏覽器認爲有效的證書與JDK8的信任庫之間的內容不匹配。 –

我最後在我最後一次編輯後重新啓動機器，現在gradle build命令似乎工作正常;我不確定重新啓動會發生什麼變化，或者它是否會保持這種狀態，但至少現在它似乎正在工作。
