I'm trying to delete a Jenkins view programmatically but my Jenkins job:
import jenkins.model.*;
import jenkins.util.*;
jenkins = Jenkins.instance
def view = jenkins.getView("my-view")
jenkins.deleteView( view )
fails giving:

Build step 'Execute Groovy script' marked build as failure
I've seen solutions like this:
https://stackoverflow.com/a/42020732/343204
and suggestions on how to import like this:
Running Groovy command from Jenkins using Groovy script plugin
but not sure how to proceed.
Any suggestions?
As I understand, you use freestyle job with step "Execute Groovy script".
So, you need to change this step to "Execute system Groovy script" and your code will work.

So I've created a Groovy script, and it works in the console. I then implemented it into my job in the field Execute Groovy Script but then it failed.
Here I have the console, and I do know the imports aren't needed, but I had to try.
But When I run my job with this code, I get this error:

It look like you are using the "Execute Groovy script", but to execute scripts like in Script Console you must use the "Execute system Groovy script" step.
The normal execute will start a new Java/JVM with Groovy which is not "connected" to your Jenkins.
Only the system step will execute the script within the existing Java/JVM that is running Jenkins.
So yes I had to run it as a Execute system Groovy script, but I also had to give the full path to the lib I'm using, before it worked. the Script Console didn't need the jenkins.model... part, but the job does.
I'm trying to follow this tutorial to create a simple docker environment in as part of my Jenkins pipeline build.
I'm trying to build a couple of Docker images just as a test before I do my maven build. At the moment I have the following Groovy for my Jenkinsfile:
#!groovy
node {
stage 'Building docker env'
def dbImage = docker.build('oracle', 'docker/oracle')
def wlpImage = docker.build('liberty', 'docker/liberty')
stage 'Running maven build'
git url: 'https://mysite/myproject.git', branch: 'docker'
def mvnHome = tool 'maven 3.3.9'
sh "${mvnHome}/bin/mvn -B clean install"
}
I'm trying to have the Docker build look in the directory "docker/oracle" and call the Dockerfile in that directory, and build the Docker images named oracle, and liberty. At the moment though it's giving me this error:
Running on master in /root/.jenkins/workspace/pipeline_test

Any ideas what could be the problem with the docker build command I'm using? (or could it be something I forgot to install in Jenkins?)
The issue was I needed to install the Docker Pipeline plugin in Jenkins.
To install the plugin using the GUI:
Dashboard > Manage Jenkins > Manage Plugins > Available (tab) > docker-workflow.
As Pete says you will have to install the Docker Pipeline plugin. You can do that though the Jenkins UI.
Maybe I'm missing some part of your code, but where do you define the docker? If that's the complete Groovy script, you're trying to bind a variable which isn't declared anything, so it's not to weird that it fails, right?
Just define a docker it that's what you want, like:
def docker = "my docker" // something similar like this
And it will at-least resolve your missing property exception.
Whenever we see the error like below :
groovy.lang.MissingPropertyException: No such property:
It means , groovey script did not able to find the property mentioned post the colon sign : , so we need to either define the user defined variable/property or use the correct one from API.
If you have this issue:
groovy.lang.MissingPropertyException: No such property: docker for class: groovy.lang.Binding.
We most likely encountered the same issue, in order to fix it I only had to install the Docker Pipeline plugin in Jenkins, so all you have to do is go to:
Jenkins Homepage > Manage Jenkins > Manage Plugins > Available
Search for Docker Pipeline install it restart jenkins and you are ready to go.

I had the same issue but after I installed the Docker Pipeline plugin as #Affes Salem suggested it is working now.
I'm using this Jenkins plugin: https://wiki.jenkins-ci.org/display/JENKINS/Build+User+Vars+Plugin
With this plugin installed, if you check the box "Set jenkins user build variables", you can use the environment variable ${BUILD_USER} which gives the name of the person who built the Jenkins job.
But, I can't get the plugin to work with the Pipeline plugin (https://wiki.jenkins-ci.org/display/JENKINS/Pipeline+Plugin).
I noticed that checking that "Set jenkins user build variables" box adds the following line to the config.xml of your Jenkins job: <org.jenkinsci.plugins.builduser.BuildUser plugin="build-user-vars-plugin#1.5"/>
So I tried the following:
import org.jenkinsci.plugins.builduser.BuildUser
echo "${env.BUILD_USER}"
But it prints out null.
try use this variable:
def USER = wrap([$class: 'BuildUser']) {
return env.BUILD_USER
}
I used here and It worked !!
I'm trying to execute a simple groovy script on Jenkins' slaves using the Groovy plugin.
I'm using the execute groovy script option and not the execute system groovy script option. I'm also using the "install automatically" (install from groovy website) option of the plugin of the latest version(2.4.6) . However, the job fails and I'm getting this:

How can I overcome this issue and make it work properly?
From the Groovy plugin page:
Groovy Script vs System Groovy Script
The plain "Groovy Script" is run in a forked JVM, on the slave where the build is run. It's the basically the same as running the "groovy" command and pass in the script.
The system groovy script, OTOH, runs inside the Jenkins master's JVM. Thus it will have access to all the internal objects of Jenkins, so you can use this to alter the state of Jenkins. It is similar to the Jenkins Script Console functionality.
When not using the system Groovy, you do not have Jenkins object in your classpath. You need to make sure the required classes are accessible from the job you are running, and pass them in the "Class path" field of the "execute groovy script" step.
We can use RemoteDignostics class
The following Script runs on master but uses RemoteDignostics to run groovy on Worker Nodes/slave.
import hudson.util.RemotingDiagnostics
import jenkins.model.Jenkins
String agent_name = 'your agent name'
groovy_script = '''
println System.getenv("PATH")
println "uname -a".execute().text
'''.trim()
String result
Jenkins.instance.slaves.find { agent ->
agent.name == agent_name
}.with { agent ->
result = RemotingDiagnostics.executeGroovy(groovy_script, agent.channel)
}
println result
How do we configure running groovy scripts on slave nodes? am able to get groovy installation from manage jenkins section, but the scripts fail to run.
I am having a job with execute groovy steps and this job is supposed to run on "slave" nodes.
The System groovy option wont fit since it runs on master and the execute groovy on job configured to run on slave fails with error
/workspace/hudson5188055044238549912.groovy: 2: unable to resolve class jenkins.model.Jenkins
# line 2, column 1.
import jenkins.model.Jenkins
Seems the jars are not picked during run. Is there easy way to setup or which jenkins and groovy jars are required??
On the job configuration page there should be a drop down beside "Groovy Version" under the "Execute Groovy Script" block. You need to select the name of the groovy install that is on master. Jenkins will grab the necessary files from master.
