Nexus3 清理策略因 NullPointerException 而失败

如何解决Nexus3 清理策略因 NullPointerException 而失败

我正在使用 nexus:3.20.1-01。

我已经为 maven-snapshot 设置了清理策略。按照下面的屏幕

清理策略预览，所以这表明此策略将清理显示的文件/目录。

但是当我运行 CleanUp Service 时

我收到一个异常，它没有清理快照。以下是日志

有人可以帮我找到问题吗。

谢谢

解决方法

我在任何博客上都没有发现任何与此异常相关的内容。

解决方案：

我只是重新启动了 nuxus docker 并且它正在工作。
