Maven 尽管mvn clean install在命令提示符下运行良好，但在jenkins中构建失败

我是詹金斯和马文的新手。 我在eclipse中有一个maven项目。我用詹金斯来执行死刑。 当我执行命令“mvn clean install”时，它工作得很好。但当我通过Build now在Jenkins中执行时，它抛出空指针异常

请帮我解决这个问题

它现在运转良好。我在Pre步骤下添加了命令“mvn clean install”。

Maven Project->Configure->Pre Steps->add over command->Save.

您忘记了日志。添加的日志。。请帮助我。请添加完整的日志输出，而不仅仅是摘录。你怎么称呼Maven的？哪个Maven版本？哪一个Jenkins版本？对我来说，删除Jenkins工作区后它起作用了
