无法解析 Maven 站点插件或其依赖项之一
Maven site plugin or one of it's dependencies could not be resolved
我所在的网络受限，不允许从互联网下载文件，因此我们有一个本地 Nexus 服务器 运行ning。
白名单代理不是一个选项
我需要更新我们的公共 java 库存储库，我已经成功创建了一个将新工件上传到 nexus 的过程。
- 使用允许连接到中央
的settings.xml
- 使用声明了新依赖项的 pom 下载所有新工件
- 这会将所有 jars/poms 下载到
~/.m2/repository。我有一个 python 脚本，它将存储库的内容复制到另一个临时目录，然后它会遍历这个目录，并且 运行s mvn deploy:deploy-file 遇到每个 jar/pom。
- 然后我将我的 settings.xml 换成一个只允许连接到 nexus 而不是中央的。
理论上这听起来不错，但是当我 运行 mvn dependency:resolve 与本地 settings.xml 我得到以下

它在解决许多 maven 插件的依赖关系时遇到问题，我尝试查看插件 poms 并检查我是否在 Nexus 中有依赖关系，但我显然仍然缺少一些。
有没有一种简单的方法可以查看它无法解析哪些依赖项？

所以运行mvn dependency:resolve -X给了我更具体的细节
