如何查看哪个URL Tycho是镜像的？

Question

我正在跟踪博客带有Tycho的镜像Eclipse p2存储库来反映一些可安装的单元。此外，我还跟踪Tycho/目标平台/认证和镜像来配置settings.xml中的其他位置。启动mvn package -s ./settings.xml时，控制台显示：

这个过程很慢，花了将近两个小时。也许我的settings.xml不起作用。我不知道Tycho被困在什么地方。也许我已经配置了以https://download.eclipse.org开头的URL来代替我的镜像URL，但是Tycho是从http://download.eclipse.org获取的，所以它忽略了我的镜像配置。也许Tycho无法在指定的镜像位置找到一些工件。我不知道。控制台应该像Maven镜像那样告诉我这一点。Tycho没有。是否需要额外的配置来打印Tycho取得了多少进展？镜像过程在黑匣子中运行，这让我感到焦虑--它应该什么时候结束？泰丘是怎么被困住的？我能做什么?想象一下等待Windows更新结束的感觉。我希望有一个调试选项来告诉我所有的进展。我需要得到充分的信息。感谢你的帮助！

从这条信息中我可以看到Tycho0.16.0中有关于进度的控制台输出。后来的Tycho版本发生了什么变化，让用户陷入了黑暗之中？

Answer 1

命令行选项-X (或--debug，产生执行调试输出)已经给出了答案。

为什么Tycho忽略settings.xml中的镜像配置？答:不，Tycho不忽略配置。但是tycho-p2-extras-plugin只是不支持镜像配置。这些配置只对在<repositories>标记下在pom.xml中编写的存储库生效。Tycho尚未支持使用镜像镜像存储库。(对于大多数开发人员来说，这听起来可能有些奇怪。)Tycho支持的只是从镜像存储库中提取Maven项目的依赖项。
