ubuntu – Jenkins发布ssh成功连接服务器但是put文件失败

我有一个问题,当我构建我的工作时,它无法将我的文件放在控制台输出的服务器目录中我得到消息“错误：发布时异常,异常消息[权限被拒绝]”

我有以下日志输出：

SSH: Connecting from host [rp_ci]
SSH: Connecting with configuration [web-dev] ...
SSH: Creating session: username [ubuntu],hostname [xx.xx.xx.xxx],port [22]
SSH: Connecting session ...

SSH: Disconnecting configuration [web-dev] ...
ERROR: Exception when publishing,exception message [Permission denied]
Build step 'Send build artifacts over SSH' changed build result to UNSTABLE
Finished: UNSTABLE

对于目标服务器我使用nginx在AWS EC2上使用ubuntu服务器.

有人知道如何解决这个问题吗？我没有在网上找到任何线索.
谢谢！
