Java jdk版本更改后Maven不使用来自settings.xml的镜像

我有一个打印Hello world的简单java应用程序。我在settings.xml中提到了一个代理服务器，Maven在运行时应该使用它（在Jenkins中运行良好）。 以前，我使用的是jdk7。现在，我将其更改为jdk1.8.0_45并再次运行该应用程序（在Jenkins中）。现在我可以在日志中看到maven正在搜索默认的存储库，它不应该是

现在的错误是：

提前谢谢

它说，

您是否阅读了

？日志是否说明在尝试转到maven central之前，它至少尝试访问您的镜像以下载插件？它应该在您发布的代码片段上方提到这一点。
