我正在尝试使用 Maven、Jenkins、SVN 和 Nexus 设置环境。我通过 SVN 将 Jobs 添加到 Jenkins，但由于 Maven 错误，Jenkins 无法构建这些 Jobs。
这是错误日志

如果我通过命令行使用 Maven 构建 Jenkins，一切正常。它从 Nexus 下载所有依赖项。我还必须向 Maven 添加代理。
我下载了配置文件管理插件来为 Maven 添加自己的 settings.xml：
<mirror>
<id>nexus</id>
<url>http://mynexusadress.com:6060/nexus/content/groups/public</url> <mirrorOf>central</mirrorOf>
对代理的访问在 Nexus 配置文件中配置。（如上所述，在本地使用 Maven 工作正常，它从 Nexus 下载所有依赖项并将构建 jar 上传到它）
