我有一个Freestyle Jenkins项目，该项目使用bitbucket作为SCM，并使用ssh作为协议和私钥（而不是用户/密码）。

当我在master上构建项目时，它在以下stacktrace下失败，而在agent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用户身份运行此命令没有问题。
• 詹金斯可写文件夹/ var / lib / jenkins / workspace / foo_test @ tmp
• 我正在使用最新版本的Git Client 2.7.4

可能是什么问题？
