Jenkins管道ansible插件：ansible playbook失败

我有一本Ansible的剧本，我正试图从詹金斯的管道中运行。我从源代码运行Ansible，我用Ansible插件调用它。以下是我的管道脚本中的部分：

withEnv(["PYTHONPATH=/home/ec2-user/ansible/lib"]) {
                ansiblePlaybook([
                    colorized: true,
                    credentialsId: 'my-creds',
                    installation: 'ansible-2-2-0',
                    inventory: 'staging',
                    playbook: 'deploy.yml',
                    extras: "--extra-vars 'app_build_id=${git_commit}'"
                ])

            }

我已经验证了Ansible可执行文件的路径是正确的，$PYTHONPATH也是正确的。但当我运行管道时，它是这样做的：

[Pipeline] ansiblePlaybook
[planet-healthcare-pipeline] $ /home/ec2-user/ansible/bin/ansible-playbook deploy.yml -i staging -f 5 --private-key /home/ec2-user/jenkins/workspace/REDACTED.key -u ec2-user --extra-vars app_build_id=24a6431

知道我做错了什么吗？为什么Ansible不能加载自己的常量？

尝试以用户jenkins的身份运行它

sudo su -s /bin/bash jenkins

怎么用？你所说的以用户身份运行它是什么意思，詹金斯。屏幕截图会有所帮助。
