Jenkins Interactive Shell

repl.groovy

script {
  while (true) {
    def cmd = input(message: 'Jenkins Interactive Shell', parameters: [
      string(name: 'cmd', description: 'Enter a command or leave blank to continue job.', defaultValue: '')
    ], ok: 'Execute')
    if (cmd == '') { print 'Continuing job...'; break; }
    try { sh cmd } catch (err) { }
  }
}

This will pause a job and present the user with an input field they can use to execute shell commands from the same context as the job itself, which is not only more convenient than SSH-ing into the Jenkins node, but also ensures that the environment is exactly the same as the one used by the executor.

Using in Declarative Pipelines

This snippet can be dropped into a Delcarative Pipeline between any other instructions in a steps block to pause the job at that point.

pipeline {
  stages {
    stage('test') {
      steps {
        // Drop snippet here.
      }
    }
  }
}

Example

Very nice!
The Jenkins Pipeline Utilities library by ebay provides steps similar to this one, mainly:
