Jenkins CI Pipeline Scripts not permitted to use method groovy.lang.GroovyObject

Quickfix Solution:

I had similar issue and I resolved it doing the following

  1. Navigate to jenkins > Manage jenkins > In-process Script Approval
  2. There was a pending command, which I had to approve.

In process approval link in Jenkins 2.61



Alternative 1: Disable sandbox

As this article explains in depth, groovy scripts are run in sandbox mode by default. This means that a subset of groovy methods are allowed to run without administrator approval. It's also possible to run scripts not in sandbox mode, which implies that the whole script needs to be approved by an administrator at once. This preventing users from approving each line at the time.

Running scripts without sandbox can be done by unchecking this checkbox in your project config just below your script: enter image description here

Alternative 2: Disable script security

As this article explains it also possible to disable script security completely. First install the permissive script security plugin and after that change your jenkins.xml file add this argument:

-Dpermissive-script-security.enabled=true

So you jenkins.xml will look something like this:

<executable>..bin\java</executable>
<arguments>-Dpermissive-script-security.enabled=true -Xrs -Xmx4096m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=80 --webroot="%BASE%\war"</arguments>

Make sure you know what you are doing if you implement this!


You have to disable the sandbox for Groovy in your job configuration.

Currently this is not possible for multibranch projects where the groovy script comes from the scm. For more information see https://issues.jenkins-ci.org/browse/JENKINS-28178


I ran into this when I reduced the number of user-input parameters in userInput from 3 to 1. This changed the variable output type of userInput from an array to a primitive.

Example:

myvar1 = userInput['param1']
myvar2 = userInput['param2']

to:

myvar = userInput

To get around sandboxing of SCM stored Groovy scripts, I recommend to run the script as Groovy Command (instead of Groovy Script file):

import hudson.FilePath
final GROOVY_SCRIPT = "workspace/relative/path/to/the/checked/out/groovy/script.groovy"

evaluate(new FilePath(build.workspace, GROOVY_SCRIPT).read().text)

in such case, the groovy script is transferred from the workspace to the Jenkins Master where it can be executed as a system Groovy Script. The sandboxing is suppressed as long as the Use Groovy Sandbox is not checked.


To get the version of a maven project, I usually use mvn binary in the sh block as follows. No need for admin permissions.

stage("Compile") {
    steps {
       sh """
         mvn help:evaluate -Dexpression=project.version -q -DforceStdout > version.txt
       """
    }
}
