title: How to copy a shell script to created job in jenkins using job dsl plugin?
body: <p>I have some shell script as like below</p>
  
  <pre><code>echo $BUILD_NUMBER
  echo $GIT_BRANCH
  echo $SUNNY
  </code></pre>
  
  <p>How to copy the snippet to created job using dsl script?
  I know we can achieve it by <code>shell(readFileFromWorkspace('build.sh'))</code></p>
  
  <p>But is there anyway copy the script using dsl script instead of providing using a .sh file?</p>
