我有一个 Freestyle Jenkins 项目，它使用 bitbucket 作为 SCM，使用 ssh 作为协议和私钥（不是用户/密码）。
当我在 master 上构建项目时，它失败并显示以下堆栈跟踪，而它在代理上运行良好。
注意错误提到：
stderr：致命：无法执行'/var/lib/jenkins/workspace/foo_test@tmp/ssh1377177620135545595.sh'：权限被拒绝
致命：无法分叉
我检查了以下内容：
- 从命令行以 jenkins 用户身份运行它显示没有问题。
- Jenkins 可写入文件夹 /var/lib/jenkins/workspace/foo_test@tmp
- 我正在使用最新版本Git 客户端 https://plugins.jenkins.io/git-client 2.7.4
可能是什么问题？
堆栈跟踪：

检查主服务器上的工作区目录是否未使用“noexec”选项挂载。
- 查看 /etc/fstsab 以查找这些设置
- 删除 noexec
- 重启机器
