我假设这是由某些Linux安全功能引起的阻止创建/ var / lib / jenkins / workspace / videovixx而没有正确的权限
我可能没有。这是问题，我该如何解决？

I'm assuming that this caused by some linux security feature that stops the /var/lib/jenkins/workspace/videovixx from being created without the correct permissions which I might not have. Is this the problem and how do I solve it?

推荐答案

这里有很多东西。

您未在作业配置中选择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。

You either didn't select Maven version in Job configuration. Or you didn't configure Jenkins to install a Maven version. Or you expected to use locally installed Maven on the Slave, but it's not configured for jenkins user.

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。

Since I don't know what you've configured (or didn't configure) and what you expected to use, I can't answer directly, but I can explain how it works.

• 你必须在本地安装Maven


• 您必须能够使用 jenkins启动它用户
  
  

• You must have Maven locally installed
• You must be able to launch it with jenkins user
  

1. 执行 sudo jenkins ，然后在你的Slave上执行 mvn 以验证 jenkins 用户可以运行 mvn


2. 如果失败，则需要正确安装/配置Maven

1. Execute sudo jenkins, and then execute mvn on your Slave to verify that jenkins user can run mvn
2. If that fails, you need to properly install/configure Maven

在作业配置中，对于Maven版本，必须选择默认。这是使用在节点上本地安装的版本的设置

In Job configuration, for Maven Version, you must select Default. This is the setting that uses the version that's installed locally on the node

• 您必须转到Jenkins全局配置，并使用自动安装程序（从网络上）配置Maven版本。


• 在作业配置中，对于Maven版本，您必须选择 您刚刚配置的特定版本。

• You must go to Jenkins Global Configuration, and configure a Maven version with automatic installer (from the web).
• In Job configuration, for Maven Version, you must select that particular version that you've just configured.
