Push "demo.txt" under the local "test-dir" to the remote "/tmp/ssh-test/". The "test-dir" directory will be created automatically. It is not possible to put "demo.txt" under the "/tmp/ssh-test/" directory.

Even if I switch the working directory to "test-dir", it still doesn't work.
Example

pipeline {
 agent any
 stages {
  stage('Test') {
   steps {
    sh 'mkdir -p test-dir && echo "test" > test-dir/demo.txt' // Create local directory structure
    
     sshPut remote: [host: 'remote-ip', user: 'user', password: 'pass'],
       from: '.', into: '/tmp/ssh-test' // Transfer current directory
    }
    sshCommand remote: [host: 'remote-ip', user: 'user', password: 'pass'],
       command: 'ls -l /tmp/ssh-test' // Verify remote path
   }
  }
 }
}

 Observed Behavior

Remote path contains local directory structure:

/tmp/ssh-test/test-dir/demo.txt

Expected Behavior

Files should be directly copied to specified into path:

/tmp/ssh-test/demo.txt
