title: How to add build parameters to jenkins multibranch pipeline?
body: <p>I would like to add additional build parameters to my jenkins mutibranch pipeline job.</p>
  
  <p>Relevant versions:</p>
  
  <ul>
  <li>org.jenkins-ci.plugins:script-security:1.19</li>
  <li>org.kohsuke:groovy-sandbox:1.10</li>
  <li>org.jenkins-ci.main:jenkins-war:2.0   </li>
  <li>org.jenkins-ci.plugins.workflow:workflow-aggregator:2.0</li>
  </ul>
  
  <p>My Jenkins file:</p>
  
  <p>As you can see the first four lines are supposed to add the build parameter option.</p>
  
  <pre><code>import hudson.model.*
  def build = Thread.currentThread().executable;
  build.addAction(new ParametersAction(new StringParameterValue("SVN_UPSTREAM", build.getEnvVars()['SVN_REVISION'])));
  println "SVN_UPSTREAM:" + build.getEnvVars()['SVN_UPSTREAM'];
  
  node('dockerSlave') {
     stage 'Checkout'
     checkout scm
  
     def mvnHome = tool 'M3'
  
     stage 'VersionSet'
     def v = version()
     if (v) {
       echo "Building version ${v}"
     }
     sh "${mvnHome}/bin/mvn versions:set -DnewVersion=${env.BUILD_NUMBER}"
  
     stage 'Build'
     sshagent(['601b6ce9-37f7-439a-ac0b-8e368947d98d']) {
        sh 'echo SSH_AUTH_SOCK=$SSH_AUTH_SOCK' 
        sh "${mvnHome}/bin/mvn -B -Dmaven.test.failure.ignore clean deploy scm:tag"
        step([$class: 'JUnitResultArchiver', testResults: '**/target/surefire-reports/TEST-*.xml'])
     }
  }
  
  def version() {
    def matcher = readFile('pom.xml') =~ '&lt;version&gt;(.+)&lt;/version&gt;'
    matcher ? matcher[0][1] : null
  }
  </code></pre>
  
  <p>Unfortunately i get the following error:</p>
  
  <blockquote>
    <p>org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException:
    Scripts not permitted to use staticMethod java.lang.Thread
    currentThread at</p>
  </blockquote>
  
  <p>Is there a way to add the static method to a whitelist or add a build parameter via a different way?</p>

  <p><em>Update:</em></p>
  
  <p>Seems like disabling the sandbox mode is not possible at the moment.</p>
