How to make Jenkins and cygwin friends?

Question

Cygwin

I need to set up synchronization under Windows using Jenkins.
To do this, I installed cygwin with ssh and rsync. In cygwin I set up ssh to a remote server and set up rsync. Everything works and files are thrown.
In Jenkins, I installed the "SSH plugin" plugin, where I registered the data of the remote server, and created a task with the build step "Execute shell script on remote host using ssh", where the data of the remote server was highlighted in the "SSH site", and in the "Command" I entered the command that I entered in cygwin "rsync -rtuv cygdrive/j/Jenkins/workspace/workspace/www/* [email protected]:www/test/" .
Now, when starting the task, after executing the command "rsync -rtuv cygdrive/j/Jenkins/workspace/workspace/www/* [email protected]:www/test/" nothing happens, as if something somewhere then it hangs or waits for a response from the server. I repeat that in cygwin the same command runs normally, quickly and everything is synchronized.
I have the impression that I somehow did not configure Jenkins correctly.
Please write how to make friends Jenkins and cygwin.
