Failing a build in Jenkinsfile

You can use the error step from the pipeline DSL to fail the current build.

error("Build failed because of this and that..")

I have shown below different ways of error handling for declarative approach:

failfast in parallel pipeline

https://issues.jenkins-ci.org/browse/JENKINS-55459?page=com.atlassian.jira.plugin.system.issuetabpanels%3Achangehistory-tabpanel

If a user has a Declarative Pipeline script with parallel stages, and they set failFast true for those stages, if one of the stages fails then the build is immediately aborted.

NOTE: sh 'false' --> Can fail the stage

pipeline {    agent any    stages {         stage('Validate Fail fast') {             failFast true             parallel {                  stage('stage A') {                    steps {                        echo 'stage A started'                        sleep 5                        sh 'false'                        echo 'stage A Ended' //will not execute because of above sh return                    }                }                stage('stage B') {                    steps {                        echo 'stage B started'                        sleep 10                        echo 'stage B Ended' //will not execute because of above stage fail                    }                }                 stage('stage C') {                    steps {                        echo 'stage C started'                        echo 'stage C Ended' //May complete before Stage A fails                    }                }             }         }         stage('final stage sequential') {             steps {                 script {                     echo "The complete run!"                 }             }         }     }}

When failFast true it terminates the parallel tasks.

When "failFast false" it still continue executes other parallel tasks.

Try-catch block in Jenkins pipeline script

In declarative style of pipeline, so you must not use try/catch blocks (which are for Scripted Pipelines),The key is to put try...catch in a script block in declarative pipeline syntax. Then it will work. This might be useful if you want to say continue pipeline execution despite failure (eg: test failed, still you need reports..)

NOTE: sh 'invalid command' --> Can fail the stage even though it is part of script.

script {  try {      sh 'do your stuff'  } catch (Exception e) {      sh 'Handle the exception!'  }}    try {        sh 'might fail'        echo 'Succeeded!'    } catch (err) {        echo "Failed: ${err}"    } finally {        sh './tear-down.sh'    }pipeline {    agent any    stages {         stage('Validate Fail fast') {             failFast true             parallel {                  stage('stage A') {                    steps {                        echo 'stage A started'                        sleep 5                        script {                              try {                                  sh 'I_AM_NOT_VALID_CMD'                              } catch (Exception e) {                                  sh 'EVEN_I_AM_INVALID_2_FAIL_THIS_BUILD!'                              }                        }                        echo 'stage A Ended' //will not execute because of above sh return                    }                }                stage('stage B') {                    steps {                        echo 'stage B started'                        sleep 10                        echo 'stage B Ended' //will not execute because of above stage fail                    }                }                 stage('stage C') {                    steps {                        echo 'stage C started'                        echo 'stage C Ended' //will not execute because of above stage fail                    }                }             }         }         stage('final stage sequential') {             steps {                 script {                     echo "The complete run!"                 }             }         }     }}Started by user adminRunning in Durability level: MAX_SURVIVABILITY[Pipeline] Start of Pipeline[Pipeline] nodeRunning on Jenkins in /Users/Shared/Jenkins/Home/workspace/ErrorHandling[Pipeline] {[Pipeline] stage[Pipeline] { (Validate Fail fast)[Pipeline] parallel[Pipeline] { (Branch: stage A)[Pipeline] { (Branch: stage B)[Pipeline] { (Branch: stage C)[Pipeline] stage[Pipeline] { (stage A)[Pipeline] stage[Pipeline] { (stage B)[Pipeline] stage[Pipeline] { (stage C)[Pipeline] echostage A started[Pipeline] sleepSleeping for 5 sec[Pipeline] echostage B started[Pipeline] sleepSleeping for 10 sec[Pipeline] echostage C started[Pipeline] echostage C Ended[Pipeline] }[Pipeline] // stage[Pipeline] }[Pipeline] script[Pipeline] {[Pipeline] sh+ I_AM_NOT_VALID_CMD/Users/Shared/Jenkins/Home/workspace/ErrorHandling@tmp/durable-5fc28a9a/script.sh: line 1: I_AM_NOT_VALID_CMD: command not found[Pipeline] sh+ 'EVEN_I_AM_INVALID_2_FAIL_THIS_BUILD!'/Users/Shared/Jenkins/Home/workspace/ErrorHandling@tmp/durable-5e73fa36/script.sh: line 1: EVEN_I_AM_INVALID_2_FAIL_THIS_BUILD!: command not found[Pipeline] }[Pipeline] // script[Pipeline] }[Pipeline] // stage[Pipeline] }Failed in branch stage A[Pipeline] }[Pipeline] // stage[Pipeline] }Failed in branch stage B[Pipeline] // parallel[Pipeline] }[Pipeline] // stage[Pipeline] stage[Pipeline] { (final stage sequential)Stage "final stage sequential" skipped due to earlier failure(s)[Pipeline] }[Pipeline] // stage[Pipeline] }[Pipeline] // node[Pipeline] End of PipelineERROR: script returned exit code 127Finished: FAILURE

How to throw exception in jenkins pipeline?

node { try { error 'Test error' } catch (ex) { echo 'Error handled' } }  //node has to be replaced with scripts

error can make the parallel pipeline stages to stop executing it.

The below 'unstable' command is similar to setting currentBuild.result = 'UNSTABLE'.

This will not stop the executions.

catchError {        sh 'might fail'    }

This is equivalent to setting currentBuild.result = 'FAILURE'

This will not stop the executions.

If you wish to use certain methods/class you may get a similar message:

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use new java.lang.RuntimeException java.lang.String

Typically it is followed by a link to the Scripts Approval page in your Jenkins (which you can update if you are an admin).

For example from my own Jenkins:

Scripts not permitted to use method org.w3c.dom.Element setAttribute java.lang.String java.lang.String. Administrators can decide whether to approve or reject this signature. org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use method org.w3c.dom.Element setAttribute java.lang.String java.lang.String

The text Administrators can decide whether to approve or reject this signature. should be a link you can follow to the Jenkins Script Approval Page.It's URL is typically:

http://<Jenkins URL>/scriptApproval/

Or should be accessible via: Jenkins -> Manage -> In-process Script Approval

On this page you can approve that scripts can use these method/classes.

However you should just be able to throw an Exception - I can do this without needing to do a script approval.

For example within my Pipeline groovy script:

throw new Exception('Some error text')

This output in the Jenkins build console:

java.lang.Exception: Some error textat WorkflowScript.processProjectsToUpdate(WorkflowScript:106)at ___cps.transform___(Native Method)at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62)at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)at java.lang.reflect.Constructor.newInstance(Constructor.java:423)at org.codehaus.groovy.reflection.CachedConstructor.invoke(CachedConstructor.java:83)at org.codehaus.groovy.runtime.callsite.ConstructorSite$ConstructorSiteNoUnwrapNoCoerce.callConstructor(ConstructorSite.java:105)at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCallConstructor(CallSiteArray.java:60)at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callConstructor(AbstractCallSite.java:235)

This outputs quite a long stacktrace, the first line:

at WorkflowScript.processProjectsToUpdate(WorkflowScript:106)

Line 106 should be the the line in your Pipeline groovy script where the Exception was thrown, which may be useful information to you.

If you are not interested in the stacktrace, as in other answers just use error:

error('Some error text')

This is mentioned in the Jenkins Pipeline documentation: https://jenkins.io/doc/pipeline/steps/workflow-basic-steps/#error-error-signal

error: Error signal Signals an error. Useful if you want to conditionally abort some part of your program. You can also just throw new Exception(), but this step will avoid printing a stack trace.
