How to use the camel-ssh feature to help me manage remote services such as the nginx reload command

[一剑飘红]

I have a need

First I sync the file to the web server via camel-sftp

After transferring the file, do the nginx -s reload command on each server.

My code is as follows

But why pollcomand doesn't work

from("file:I:/workProject/java/xxxx/luaFiles/").multicast().to("direct:a",
"direct:b").end().to("direct:c");
        from("direct:a").to("sftp://
root@192.168.56.14/xxxx/controllers/gen/?password=root&stepwise=true&runLoggingLevel=TRACE&throwExceptionOnConnectFailed=true&idempotent=true
");
        from("direct:b").to("sftp://
root@192.168.56.14/?password=root&stepwise=true&runLoggingLevel=TRACE&throwExceptionOnConnectFailed=true&idempotent=true
");
        from("direct:c").to("ssh://
root:root@192.168.56.14?poll-command=reboot%0A&pollCommand=nginx -s
reload %0A").log("done ！！${body}");
