我假设这是由某些 linux 安全功能引起的，该功能阻止/var/lib/jenkins/workspace/videovixx 在没有正确权限的情况下创建我可能没有.这是问题吗?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.

您要么没有在作业配置中选择 Maven 版本.或者你没有配置 Jenkins 来安装 Maven 版本.或者你希望在 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，我无法直接回答，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.

• 您必须在本地安装 Maven
• 您必须能够使用 jenkins 用户启动它

1. 执行sudo jenkins，然后在你的Slave上执行mvn验证jenkins用户是否可以运行mvn
2. 如果失败，您需要正确安装/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，您必须选择 Default.这是使用本地安装在节点上的版本的设置

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 全局工具配置，并使用自动安装程序(来自网络)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那个特定版本.
