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

问题

I am Using Jenkins 2 for compiling Java Projects, I want to read the version from a pom.xml, I was following this example:

https://github.com/jenkinsci/pipeline-plugin/blob/master/TUTORIAL.md

The example suggest:

It seems that there is some security problem accessing the File System but I can\'t figure out what it is giving (or why) that problem:

I am just doing a little bit different than the example:

def version() {
    String path = pwd();
    def matcher = readFile(\"${path}/pom.xml\") =~ \'<version>(.+)</version>\'
    return matcher ? matcher[0][1] : null
}

The Error I am getting when running the \'version\' method :

I am using these versions: Plugin Pipeline 2.1 Jenkins 2.2

Quickfix

I had similar issue and I resolved it doing the following

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

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:

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!

回答2:

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

回答3:

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.

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
