我假设这是由一些Linux安全功能引起的,它阻止创建/ var/lib/jenkins/workspace/videovixx而没有我可能没有的正确权限.这是问题,我该如何解决？

Answer 1

这里有很多东西.

您要么没有在作业配置中选择Maven版本.或者您没有配置Jenkins来安装Maven版本.或者您希望在Slave上使用本地安装的Maven,但它没有为jenkins用户配置.

由于我不知道你配置了什么(或没有配置)以及你期望使用什么,我不能直接回答,但我可以解释它是如何工作的.

如果要在主/从上使用本地安装的Maven

• 您必须在本地安装Maven
• 您必须能够与jenkins用户一起启动它
  
  1. 执行sudo jenkins,然后mvn在Slave上执行以验证jenkins用户是否可以运行mvn
  2. 如果失败,则需要正确安装/配置Maven
• 在作业配置中,对于Maven版本,您必须选择Default.这是使用在节点上本地安装的版本的设置

如果你想让Jenkins为你安装Maven

• 您必须转到Jenkins全局配置,并使用自动安装程序(从Web)配置Maven版本.
• 在作业配置,Maven的版本,你必须选择是你刚刚配置的特定版本.

Answer 2

如果您只是寻找最简单的解决方案,那么您应该去全球jenkins配置

http://localhost:32773/configureTools/

并配置maven这样的

然后你必须去你的项目.您已构建内部设置.选择你一分钟前创建的maven.
