Pre send script in groovy for jenkins - groovy

i have two dependent jobs. i need help for groovy script in jenkins, for writing pre send script for email-ext plugin.
i want to check whether buid reason is upstream cause, then set cancel variable=true
But i don't know how to write if condition in groovy for jenkins..For seperate jobs, will there be any seperate classes in jenkins(so i can create instance and call upstream cause)
is there any way to check build cause of downstream job is due to upstream..
Please help me on this code snippet..

Use Build.getCauses() method. It will return a list of causes for the build. Loop over it and check if there is an object of hudson.model.Cause.UpstreamCause among them.
To get the build object, use the following code snippet:
def thr = Thread.currentThread()
def build = thr?.executable
FYI, here is a link to the complete Jenkins Module API.

Run generic groovy script assertion in SoapUI

Is it possible to / how do you run a groovy script from a SoapUI assertion without copy/pasting the script into all of your test steps where you need the same script executed? Is it possible to write a script outside of the assertion and run the script like you are calling a method? So that you can reuse the assertion script in multiple test steps.
So far, I've tried to call a groovy test step from within the assertion, but the run() method requires a testRunner variable which is unavailable from within the assertion. I've also tried to write a groovy script as a subsequent test step (not an assertion) that calls another groovy test step script, but I was unable to transfer the response from one test step to the next (Honestly, I'd rather not create test steps that are really just assertions).
Note: this is not a duplicate of How to create variables in soapui test case that can be accessed across all test steps - groovy test step & script assertion test step? because that question pertains to storing properties, not reusing scripts.
I was able to finally figure out my 2nd approach: add another groovy script as a subsequent test step that has assertions and passes the response. The script is:
context.response = context.expand('${MyTestStep#Response}') // store response to context variable
Object result = testRunner.testCase.testSuite.testCases['Validate Response'].testSteps['Validate Response'].run(testRunner, context)
if(result.getError() != null) {
log.error("error", result.getError())
assert false
}
assert true
MyTestStep is the test step before the groovy script. Validate Response is the name of the test case of the groovy script which is also called Validate Response and is executed via the run method.

Groovy Script for JIRA-actions

I want to achieve the following using Adaptavist Scriptrunner in JIRA: A user comments on an issue and triggers a Scriptrunner custom script. If the issue is in the state "waiting for customer reply" and the user is a customer, trigger the workflow-transition "respond to question" and transfer the issue into the state "customer responded".
The Adaptavist Scriptrunner-Plugin uses Groovy as its language of choice for custom scripts. Unfortunately I have never worked with Groovy before and thus have no idea what I have to do to make this work. Out of the examples in the Scriptrunner docs I made the following:
import com.atlassian.jira.component.ComponentAccessor
def issue = event.issue
def workflow = ComponentAccessor.getWorkflowManager().getWorkflow(issue)
def wfd = workflow.getDescriptor()
def actionName = wfd.getAction(transientVars["actionId"] as int).getName()
This is supposed to get me the current workflow step but doesn't work. Would anyone be so kind, to help me write this script?
Cheers!
There's already available Script Listener called Fast-track transition an issue. You need just to create a new instance of it, bind it to your project and Issue Commented event, and add extra condition like issue.status.name == 'Waiting For Customer Reply' && currentUser == issue.reporter, and specify the transition. If you change workflow, you might need to update a listener too.
Also, these listeners, post-functions etc. are implemented as 'canned' scripts (classes implementing certain interface) which are available as plain groovy files in the plugin itself in the JAR file, they can teach a lot.

Jenkins Workflow Error When Accessing Variable Inside a Closure

I'm using some groovy inside a Jenkins Workflow script that includes a closure.
def newMarkup = new StreamingMarkupBuilder().bind {
mkp.yield(xml)
}.toString()
As I understand it mkp should be a variable made available inside closures when using StreamMarkupBuilder, however when I try and run this I get the error,
groovy.lang.MissingPropertyException: No such property: mkp for class: WorkflowScript
So my question is why doesn't Jenkins recognise that mkp is a property of the StreamMarkupBuilder class and not the workflow script?
Sounds like a bug in groovy-cps. Try encapsulating your logic inside a method marked with the #NonCPS annotation. If it starts working, then groovy-cps is to blame, and you can file a bug in the Jenkins JIRA in the workflow-plugin component with steps to reproduce, although I suspect even with the MissingPropertyException fixed the code would still not run due to JENKINS-26481.

Jenkins Script to Restrict all builds to a given node

We've recently added a second slave node to our Jenkins build environment running a different OS (Linux instead of Windows) for specific builds. Unsurprisingly, this means we need to restrict builds via the "Restrict where this project can be run" setting. However we have a lot of builds (100+) so the prospect of clicking through them all to change this setting manually isn't thrilling me.
Can someone provide a groovy script to achieve this via the Jenkins script console? I've used similar scripts in the past for changing other settings but I can't find any reference for this particular setting.
Managed to figure out the script for myself based on previous scripts and the Jenkins source. Script is as follows:
import hudson.model.*
import hudson.model.labels.*
import hudson.maven.*
import hudson.tasks.*
import hudson.plugins.git.*
hudsonInstance = hudson.model.Hudson.instance
allItems = hudsonInstance.allItems
buildableItems = allItems.findAll{ job -> job instanceof BuildableItemWithBuildWrappers }
buildableItems.each { item ->
boolean shouldSave = false
item.allJobs.each { job ->
job.assignedLabel = new LabelAtom('windows-x86')
}
}
Replace 'windows-x86' with whatever your node label needs to be. You could also do conditional changes based on item.name to filter out some jobs, if necessary.
You could try the Jenkins Job-DSL plugin
which would allow you to create a job to alter your other jobs. This works by providing a build step in a groovy based DSL to modify other jobs.
This one here would add a label to the job 'xxxx'. I've cheated a bit by using the job itself as a template.
job{
using 'xxxx'
name 'xxxx'
label 'Linux'
}
You might need to adjust it if some of you jobs are different types

Jenkins Groovy Postbuild use static file instead of script

Is it possible to load an external groovy script into the groovy post build plugin instead of pasting the script content into each job? We have approximately 200 jobs so updating them all is rather time consuming. I know that I could write a script to update the config files directly (as in this post: Add Jenkins Groovy Postbuild step to all jobs), but these jobs run 24x7 so finding a window when I can restart Jenkins or reload the config is problematic.
Thanks!
Just put the following in the "Groovy script:" field:
evaluate(new File("... groovy script file name ..."));
Also, you might want to go even further.
What if script name or path changes?
Using Template plugin you can create a single "template" job, define call to groovy script (above line) in there, and in all jobs that need it add post-build action called "Use publishers from another project" referencing this template project.
Update: This is what really solved it for me: https://issues.jenkins-ci.org/browse/JENKINS-21480
"I am able to do just that by doing the following. Enter these lines in lieu of the script in the "Groovy script" box:"
// Delegate to an external script
// The filename must match the class name
import JenkinsPostBuild
def postBuild = new JenkinsPostBuild(manager)
postBuild.run()
"Then in the "Additional groovy classpath" box enter the path to that file."
We do it in the following fashion.
We have a file c:\somepath\MyScriptLibClass.groovy (accessible for Jenkins) which contains code of a groovy class MyScriptLibClass. The class contains a number of functions designed to act like static methods (to be mixed in later).
We include this functions writing the following statement in the beginning of sytem groovy and postbuild groovy steps:
[ // include lib scripts
'MyScriptLibClass'
].each{ this.metaClass.mixin(new GroovyScriptEngine('c:\\somepath').loadScriptByName(it+'.groovy')) }
This could look a bit ugly but you need to write it only once for script. You could include more than one script and also use inheritance between library classes.
Here you see that all methods from the library class are mixed in the current script. So if your class looks like:
class MyScriptLibClass {
def setBuildName( String str ){
binding?.variables['manager'].build.displayName = str
}
}
in Groovy Postbuild you could write just:
[ // include lib scripts
'MyScriptLibClass'
].each{ this.metaClass.mixin(new GroovyScriptEngine('c:\\somepath').loadScriptByName(it+'.groovy')) }
setBuildName( 'My Greatest Build' )
and it will change your current build's name.
There are also other ways to load external groovy classes and it is not necessary to use mixing in. For instance you can take a look here Compiling and using Groovy classes from Java at runtime?
How did I solve this:
Create file $JENKINS_HOME/scripts/PostbuildActions.groovy with following content:
public class PostbuildActions {
void setBuildName(Object manager, String str ){
binding?.variables['manager'].build.displayName = str
}
}
In this case in Groovy Postbuild you could write:
File script = new File("${manager.envVars['JENKINS_HOME']}/scripts/PostbuildActions.groovy")
Object actions = new GroovyClassLoader(getClass().getClassLoader()).parseClass(script).newInstance();
actions.setBuildName(manager, 'My Greatest Build');
If you wish to have the Groovy script in your Code Repository, and loaded onto the Build / Test Slave in the workspace, then you need to be aware that Groovy Postbuild runs on the Master.
For us, the master is a Unix Server, while the Build/Test Slaves are Windows PCs on the local network. As a result, prior to using the script, we must open a channel from the master to the Slave, and use a FilePath to the file.
The following worked for us:
// Get an Instance of the Build object, and from there
// the channel from the Master to the Workspace
build = Thread.currentThread().executable
channel = build.workspace.channel;
// Open a FilePath to the script
fp = new FilePath(channel, build.workspace.toString() + "<relative path to the script in Unix notation>")
// Some have suggested that the "Not NULL" check is redundant
// I've kept it for completeness
if(fp != null)
{
// 'Evaluate' requires a string, so read the file contents to a String
script = fp.readToString();
// Execute the script
evaluate(script);
}
I've just faced with the same task and tried to use #Blaskovicz approach.
Unfortunately it does not work for me, but I find upgraded code here (Zach Auclair)
Publish here with minor changes:
postbuild task
//imports
import hudson.model.*
import groovy.lang.GroovyClassLoader;
import groovy.lang.GroovyObject;
import java.io.File;
// define git file
def postBuildFile = manager.build.getEnvVars()["WORKSPACE"] + "/Jenkins/SimpleTaskPostBuildReporter.GROOVY"
def file = new File(postBuildFile)
// load custom class from file
Class groovy = this.class.classLoader.parseClass(file);
// create custom object
GroovyObject groovyObj = (GroovyObject) groovy.newInstance(manager);
// do report
groovyObj.report();
postbuild class file in git repo (SimpleTaskPostBuildReporter.GROOVY)
class SimpleTaskPostBuildReporter {
def manager
public SimpleTaskPostBuildReporter(Object manager){
if(manager == null) {
throw new RuntimeException("Manager object can't be null")
}
this.manager = manager
}
public def report() {
// do work with manager object
}
}
I haven't tried this exactly.
You could try the Jenkins Job DSL plugin which allows you to rebuild jobs from within jenkins using a Groovy DSL and supports post build groovy steps directly from the wiki
Groovy Postbuild
Executes Groovy scripts after a build.
groovyPostBuild(String script, Behavior behavior = Behavior.DoNothing)
Arguments:
script The Groovy script to execute after the build. See the plugin's
page for details on what can be done. behavior optional. If the script
fails, allows you to set mark the build as failed, unstable, or do
nothing. The behavior argument uses an enum, which currently has three
values: DoNothing, MarkUnstable, and MarkFailed.
Examples:
This example will run a groovy script that prints hello, world and if
that fails, it won't affect the build's status:
groovyPostBuild('println "hello, world"') This example will run a
groovy script, and if that fails will mark the build as failed:
groovyPostBuild('// some groovy script', Behavior.MarkFailed) This example
will run a groovy script, and if that fails will mark the
build as unstable:
groovyPostBuild('// some groovy script', Behavior.MarkUnstable) (Since 1.19)
There is a facility to use a template job (this is the bit I haven't tried) which could be the job itself so you only need to add the post build step. If you don't use a template you need to recode the whole project.
My approach is to have a script to regenerate or create all jobs from scratch just so I don't have to apply the same upgrade multiple times. Regenerated jobs keep their build history
I was able to get the following to work (I also posted on this jira issue).
in my postbuild task
this.class.classLoader.parseClass("/home/jenkins/GitlabPostbuildReporter.groovy")
GitlabPostbuildReporter.newInstance(manager).report()
in my file on disk at /home/jenkins/GitlabPostbuildReporter.groovy
class GitlabPostbuildReporter {
def manager
public GitlabPostbuildReporter(manager){
if(manager == null) {
throw new RuntimeException("Manager object musn't be null")
}
this.manager = manager
}
public def report() {
// do work with manager object
}
}
