Via jenkins-cli over SSH Jenkins Pipeline creates multiple automation jobs with the help of use cases and runs them as a Jenkins pipeline. Easy bug tracking. Watch our Jenkins Pipeline webinar Now lets see how to enhance the Groovy was used to build Gradle because it can handle larger projects than Maven, which that's carrying out this build. So when the Groovy script detects an Offline Jenkins Slave Node, the console output should look something like this: Building on master in workspace /apps/jenkins/jobs/MonitorSlaves/workspace Slave is offline! getBuildCauses(' How to Execute shell script from Jenkins groovy script in Pipeline. // help to assign the ID of config file to a variable, this is optional // as ID can be used directly within 'configFileProvider' step too. That will abort the build. Jenkins Pipeline: How to get the status of the previous build. If you are using the Groovy plugin and want to leverage parameters for your system script, here are some tips. For example: println build.getClass() Outputs: For this I really like the Conditional Build Step plugin. It's very flexible, and you can choose which actions to take based on build failure or add this to your .tmux.conf 'set -g status-right "# (checkJenkins.sh jobname tmux)" Use the Pipeline Snippet Generator to generate a sample pipeline script for the build step. NOTE: Avoid using a bind mount from a folder on the host machine into /var/jenkins_home, as this might result in file permission issues (the user used inside the container might not have rights to the folder Also note that buildParameterName = 'new It's everything you need to get your Pipeline project started. Subsequent runs of that pipeline will have the default value set properly and will behave normally. Any Groovy (or Java) code you put into the script block is always executed on the Jenkins master server. No matter what agent/node you use to execute the specific stage (s). Now imagine the following scenario. Lets say you have a dedicated node in your Jenkins infrastructure to run some REST API calls to perform a production deployment. message $ git checkout . However, lots of features in the Groovy language is not supported and simple works in Groovy can be really tricky in Jenkinsfile. node ( 'whatever') {. getBuilds() // for each of such jobs we can get all the builds (or you can limit the number at your convenience) jobBuilds. values (). I'm starting to look closer to Jenkins pipelines, with a declarative Jenkinsfile in projects Git repositories. The Jenkins builds JSON API response contains a list of different actions. Via jenkins-cli over SSH Now, lets go to Jenkins pipeline groovy example. May be another Pipeline job, but more commonly a freestyle or other project. Post initialization script (init hook) You can create a Groovy script file $JENKINS_HOME/init.groovy, or any .groovy file in the directory $JENKINS_HOME/init.groovy.d/ , to run some additional things right after Jenkins starts up. Step 3 Click on the Advanced button. Once thats done, create a new Freestyle Jenkins job and add a Build Step to Execute System Groovy Script. It works as mentioned with the Groovy Post-Build Plugin, yet without any extra quoting within the string that gets executed. So I had to put the ac From the All Branch Graph, copy your successful commit, and execute the below command to work on a particular successful commit. Step 4: Once the build is complete, check the logs by clicking on the Console Output from the left side menu. I solved this problem by following this answer on StackOverflow. This script will demonstrate how to get parameters in a system groovy script. If you are talking about executing another pipeline job, the "build job" step can accomplish this: build job: '', propagate: true, wait: true propagate: Propagate errors 0 with pipeline Jenkins Pipeline / Groovy Script with Why build executor status showing two Get absolute path of the script direct How can I isolate my Jenkins pipeline How to pass Extensible Choice paramete Pass (same) parameters to multiple bui 100% Upvoted No Negative Quotes. first we get the Jenkins instance object, then using this instance we get the job object (item). It hides the information about the timeout, so we need to click on the stage and check if there was a timeout or not every time we run the pipeline. It works as mentioned with the Groovy Post-Build Plugin, yet without any extra quoting within the string that gets executed. build: Build a job. fullName} ". " This is the number you see in the "build executor status", except that the number starts from 0, not 1. As for workaround, the actual memory can be checked by invoking Groovy commands directly in Script Console (at /computer/ (master)/script ). You can use a Groovy script: Via jenkins-cli . Use Groovy script in post-build step via Groovy Post-Build plugin . You can then access Jenkins internals via Jenkins Java API . The plugin provi These will be kept so as long as they match the criteria in the normal setting options. You can use a Groovy script: Via jenkins-cli. When Groovy Plugin for Jenkins added build context variables (build, launcher, listener) to the script environment in version 1 Jenkins Cosole Output return dispatcher = USOHCOGAPP:10000 but it should return dispatcher = USOHCOGAPP901:10000 Jenkins; JENKINS-61265; Job with Extensible Groovy script does NOT get latest value when triggered by another job (Others such You will see all commits with their respective build status. import hudson.model. getEnvVariable(key) - get a variable value. (i.e: https://jenkins.example/script). We used the sort() to display them in order, but you can easily reverse or otherwise filter your image names, its just a Groovy List. Long time user of Jenkins in its "legacy" features but not using pipelines nor Jenkins X yet. Different ways to process XML file. // This code snippet assumes that the config file is stored in Jenkins. This plugin is designed to handle complex build workflows (aka build pipelines) as a dedicated entity in Jenkins. getBuildCauses() // Get a specific Cause type (in this case the user who kicked off the build), // if present. listener A BuildListener. minus( new Date (), build. Example command: println "free -m".execute ().text. Add a comment. Advantages of Jenkins are as follows: Build failures are cached during the integration stage. Watch our Jenkins Pipeline webinar //As of Pipeline Supporting APIs v2.22, there is a whitelisted API to access // build causes as JSON that is available inside of the Pipeline Sandbox. INPROGRESS + 1} else {// println "$project.name;$build.id;$build.result" results. " For that you can modify the Discard Old Builds setting in each job over a Groovy script at one go. Step 1 Go to the Jenkins dashboard and Click on the existing HelloWorld project and choose the Configure option. Step 3: Click on Build Now button on the left side menu to trigger the build. It's everything you need to get your Pipeline project started. Once we have the response body and the status code extracted, we can parse the JSON body and extract the value we are interested in. Jenkins; JENKINS-25738; Add Whitelisted methods to get the build result result} " + 1} build = build. How to allow Jenkins users to claim failed tests to indicate they'll take responsibility for them; How to fail a build when the tests fail; Try our free Jenkins Pipeline Generator tool to create a Pipeline file in Groovy syntax. def pipelineA = load "pipeline_A.groovy" pipelineA.someMethod() Other script (pipeline_a.groovy): def someMethod() { //do something } return this Pipeline job. Lets say we want to extract the value of executingTimeMillis stored as an action of type jenkins.metrics.impl.TimeInQueueAction. 1. Jenkins has script console option to execute groovy scripts on its server. You should also update the Pipeline Job Plugin to 2.7 or later, so that build parameters are defined as environment variables and thus accessible as if they were global Groovy variables.. Beware that binding['parameter.with-funny+characters'] will no longer work; use params['parameter.with-funny+characters'] instead. Automatic changes get updated in the build report with notification. (since 1.10) getResult() - get a build result string (like SUCCESS, FAILURE) (since 2.2) logContains(regexp) - returns true if the build log file contains a line matching regexp. In the bitbucket server, log on to your repository and navigate to All Branches Graph. The A stage is marked as SUCCESS which might be confusing. if [ ! -z $UPSTREAM_BUILD_DIR ];then We recommend Approach 2 to load Jenkinsfile into the Jenkins job. 5. This status code is used in a multi-stage build (like maven2) where a problem in earlier stage prevented later stages from building. Jenkins supports scripting with the Groovy language. Step 2 Browse to the section to Add a Build step and choose the option to Invoke Ant. Yay! Restart Jenkins service After Jenkins starts you need to remove $JENKINS_HOME/init.groovy.d/basic-security.groovy file Disable Setup Wizard Open Jenkins default config file and add in JAVA_ARGS next key -Djenkins.install.runSetupWizard=false In Ubuntu 16 default file places in /etc/default/jenkins Jenkins supports many credential types based on your needs. getAllItems(Job). result} " = results. " ${project. result. It is important to understand the differences between these plugins and Job DSL for managing Jenkins configuration efficiently. You can use currentBuild.rawBuild.getLog (10) (the 10 specifies that you want the last 10 lines) to get the last few lines of the log stream. ${c * 100 / sum} %": This will check if the last build was a failure and then echo that the last build failed. each{def jobBuilds = it. We can get the details of one more build jobs from jenkins by writing groovy scripts. ${build. Job DSL was one of the first popular plugins for Jenkins which allows managing configuration as code and many other plugins dealing with this aspect have been created since then, most notably the Jenkins Pipeline and Configuration as Code plugins. In the groovy template you have full access to the Jenkins object model, but there is also a build object that is available to the script automatically that is This will automatically create a 'jenkins_home' docker volume on the host machine. Pretty cool. stage ( 'blah') {. out A PrintStream (listener.logger). To set this up, you first need to install the Groovy Plugin ( https://wiki.jenkins-ci.org/display/JENKINS/Groovy+plugin ). The build should finish successfully and render a "Gradle Build Scan" icon that brings you directly to the build scan for the given build. getPreviousBuild (). There are various options to trigger Jenkins builds continuously: from polling the repository periodically, to echo 'println(jenkins.model.Jenkins.instance'\ '.getItem("").lastBuild.building)' \ | java -jar jenkins-cli.jar -s groovy = , where = means standard in. Name of a downstream job to build. After that Jenkins deletes the build artifact, but the logs, history, reports, etc for the build will be kept. jenkinsfile.groovy. This script can access classes in Jenkins and all the plugins. After that, click on the " New Item " option in Jenkins dashboard. The excellent official Groovy reference will help you to create fantastic and flexible scripts for the input boxes and the build steps.. Maven release project is automated with simple steps. echo currentBuild. WARNING: Groovy sandbox has to be disabled for this to work because it is accessing the filesystem. We have to import jenkins.model.jenkins to use method like getItemByFullName() which will return item. Use a simple name if the job is in the same folder as this upstream Pipeline job; otherwise can use relative It's so annoying to get approvals in enterprise environment(a lot of request and // Get all Causes for the current build def causes = currentBuild. Notifies the developers about build report status using LDAP (Lightweight Directory Access Protocol) mail server. Groovy is supported in Jenkinsfile for quick scripting. getLogMatcher(regexp) - returns a java.util.regex.Matcher for the first occurrence of regexp in the build log file. So lets get started Here we will try to get the details of only job. ${project. As weve seen above, both scripts using the Kotlin DSL and those using the Groovy DSL can participate in the same build. There are various options to trigger Jenkins builds continuously: from polling the repository periodically, to #!groovy node { stage(' configFile Plugin ') { // 'ID' refers to alpha-numeric value generated automatically by Jenkins. We will use this item to get details Few use cases are You might want to create credentials in the run time.You might want to use a custom groovy code with Active choice parameters.You might Trigger a new build for a given job. We can see the expected build status, but there is one issue with this approach. job : String. ISFAIL=$(ls -l /var/lib/jenkins/jobs/$UPSTR Really easy solution, maybe not to elegant, but it works! 1: Catch all the build result you want to catch (in this case SUCCESS). 2: Inject an env Jenkins. each { build-> def runningSince = groovy.time.TimeCategory. Step 1: Firstly, login into Jenkins account with valid credentials. RawBuild will also have to be whitelisted by the script security plugin once the Groovy sandbox is disabled. echo 'println(jenkins.model.Jenkins.instance'\ '.getItem("").lastBuild.building)' \ | java -jar jenkins-cli.jar -s groovy = , where = means standard in. getTime() ) def currentStatus = build. Selecting GCR Docker image version dynamically. Not Built An email will be sent if the build status is "Not Built". Try Post Build Task plugin It lets you specify conditions based on the log output fullName} ". " You can also simply throw an Exception. In this tutorial, I have written a script groovy using Jenkins pipeline call shell to create a folder and copy. An email will be sent when the build status changes from "Failure" or "Unstable" to "Success". In summary, if it is possible, use another script language (e.g., Python) for file manipulation in Jenkinsfile. def specificCause = currentBuild. There could be many use cases to use a groovy script to deal with credentials. buildStatusSummary. You can also then add custom logic in the finally block for sending notifications for build status changes (email, Slack message etc) So perhaps something like the following. Use like this: 'checkJenkins.sh ' and it will query the server with the given job name every 30s. In fact simply setting the build status in a catch clause works pretty well. Use like this: 'checkJenkins.sh tmux' and it will query the server once and output tmux coloured messages appropriate to display in a tmux status bar. launcher A Launcher. A Jenkins admin user can get a scripting console by opening in a browser the URL /script of your Jenkins instance. STATUS='Not set' It could be a password, secret file, ssh private key, or a token. You can authenticate with --username --password or with -i . sum println " ${name}: ${sum}: "status. As soon as, we will click, we will be redirected to a new page where we need to fill in the name of the job and select the type of job. Groovy script solution:- Here I am using groovy script plugin to take the build status and setting it to the environmental variable, so the envir from the job object we can get different information such as: is it currently building, is it in the queue, the last build, last build by status, and a lot more. Script - def buildNumber = Jenkins.instance.getItem('jobName').lastSuccessfulBuild.number If you get a RejectedAccessException you will have to approve those methods, see In-process Script Approval. The first run of a pipeline that has parameters will fail when execution reaches any reference to a parameterized variable. ${build. Ant as the build tool within Jenkins to build the class accordingly. The build should finish successfully and render a "Gradle Build Scan" icon that brings you directly to the build scan for the given build. Raw. instance. In addition, Gradle plugins from the buildSrc directory, an included build or an external location can be implemented using any JVM language. Reference Script Console. Do this in Jenkins by going to Manage Jenkins -> Manage Plugins -> Available, then search for Groovy Plugin. I can easily imagine reimplementing our CI job into CI pipeline (build/test/deploy if some conditions are met). each {r, c -> println "\t ${r}: ${c}: \t\tpercentage: "+ (sum ? " To create Groovy-based project, add new free-style project and select "Execute Groovy script" in the Build section, select previously configured Groovy installation and then type your command, or specify your script file name. In the second case path taken is relatively from the project workspace directory. Jenkins 1.x: If in your Jenkins job you are using Groovy plug-in, then inside Execute system Groovy script step the plug-in already provides you access to some predefined variables: build The current AbstractBuild. JENKINS_URL : Set to the URL of the Jenkins master that's running the build. E.g. The groovy scripts are executed at the end of Jenkins initialization. getBuildArtifactsByNameAndTime.groovy This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. You can authenticate with --username --password or with -i . each {name, status -> sum = status. Check out our other posts about configuring Jenkins: Using dynamic build agents to automate scaling in Jenkins; Jenkins security tips; Try our free Jenkins Pipeline Generator tool to create a Pipeline file in Groovy syntax. getPreviousBuild ()}}} results. Jenkins an open source automation server which enables developers around the world to reliably build, test, and deploy their software You should see the Welcome, lambdatest message in the Console Output. So the script in active-choice will be dynamically update if I. Basic solution (please don't laugh) #!/bin/bash You can get it this way. Docker volumes retain their content even when the container is stopped, started, or deleted. To review, open the file in an editor that reveals hidden Unicode characters. Without such a plugin, to manage job orchestration the user has to combine parameterized-build, join, downstream-ext and
