git - Jenkins 尝试从 tomcat root 构建，而不是 JENKINS_HOME

Question

我最近将我的 Jenkins 安装从独立配置移动到 Tomcat 中，并且在尝试运行管道构建时，它在初始 Git Checkout 阶段失败(如下面的 shell 输出中所示)它尝试从主页初始化我的 Ubuntu VM (/usr/share/tomcat7) 上的 Tomcat 目录，而不是定义的 JENKINS_HOME(在本例中为/var/lib/jenkins)。

Tomcat 主目录仅限于 root 访问，我确信这是设计使然。我更喜欢从 JENKINS_HOME 中项目的构建/工作区目录执行的操作。我已将 Tomcat 配置为将 JENKINS_HOME 定义到我已定义构建和工作区的目录，但由于对我来说不明显的原因，它会被忽略。在 Tomcat 上设置 Jenkins 时我是否遗漏了什么？

Answer 1

我能够通过在 tomcat 主目录中创建所需的 .ssh 目录来解决问题，并将访问角色分配给系统上的 Tomcat 用户。所有构建过程都按预期在 JENKINS_HOME 中继续运行。
