This repository contains a series of steps and variables for use inside of the Jenkins project's own link:https://ci.jenkins.io[Jenkins] instance(s).
Check link:https://github.com/jenkins-infra/documentation/blob/master/ci.adoc[this description] of available services.
== Useful steps:
=== buildPlugin
Applies the appropriate defaults for building a Maven-based plugin project on Linux and Windows.
You are advised to be using a link:https://github.com/jenkinsci/plugin-pom/blob/master/README.md[2.x or newer parent POM].
false
if you need to use Docker for containerized tests
configurations: [
[platform: 'linux', jdk: 21],
[platform: 'windows', jdk: 17],
])==== Optional arguments
repo
(default: null
inherit from Multibranch) - custom Git repository to check outuseContainerAgent
(default: false
) - uses a link:https://github.com/jenkins-infra/documentation/blob/main/ci.adoc#container-agents[Container agent] instead of a Virtual Machine: usually faster to start and generates less costs for the project
** Please note that the implementation of "containers" can be changed over timeforkCount
(default: null) - Execute tests with forkCount
Java virtual machines. If no value is specified, a single JVM is used. Common values include 0.45C
, 1
, 2
, and 1C
. If you terminate the value with a 'C', that value will be multiplied by the number of available CPU cores. This controls the number of JVM's used for the test code. Additional JVM's will be launched if the test code starts agents or uses RealJenkinsRule
.failFast
(default: true
) - instruct Maven tests to fail fastplatforms
(default: ['linux', 'windows']
) - Labels matching platforms to
execute the steps against in paralleljdkVersions
(default: [8]
) - JDK version numbers, must match a version
number jdk tool installedjenkinsVersions
: (default: [null]
) - a matrix of Jenkins baseline versions to build/test against in parallel (null means default,
only available for Maven projects)configurations
: An alternative way to specify platforms
, jdkVersions
and jenkinsVersions
(that can not be combined
with any of them).useArtifactCachingProxy
: (default: true
) - if set to false
, artifacts will not use one of the artifact caching proxy depending on the agent provider (Azure, DigitalOcean or AWS), and will directly use repo.jenkins-ci.org instead (discouraged as less reliable and consuming bandwidth)configurations
permit to provide a specific combinations of label and java/jenkins versions to use
+
[source,groovy]tests
: (default: null
) - a map of parameters to run tests during the build. The test results and the JaCoCo code
coverage results are recorded after the build with the corresponding Jenkins plugins.
** skip
- If true
, skip all the tests by setting the -skipTests
profile.
It will also skip FindBugs in modern Plugin POMs.jacoco
: (default: null
) - a map of parameters to change the default configuration of the recordCoverage
step of the https://github.com/jenkinsci/code-coverage-api-plugin[Code Coverage Plugin]. This step is called after a plugin build to record the code coverage results of JaCoCo. See https://www.jenkins.io/doc/pipeline/steps/code-coverage-api/#recordcoverage-record-code-coverage-results[recordCoverage step documentation] for a list of available configuration parameters.pit
: (default: null
) - a map of parameters to change the default configuration of the recordCoverage
step of the https://github.com/jenkinsci/code-coverage-api-plugin[Code Coverage Plugin]. See https://www.jenkins.io/doc/pipeline/steps/code-coverage-api/#recordcoverage-record-code-coverage-results[recordCoverage step documentation] for a list of available configuration parameters. Since running PIT is a time-consuming task, PIT is disabled by default. You need to enable it by setting the property skip
to false
as well.spotbugs
, checkstyle
, pmd
, cpd
: (default: null
) - a map of parameters to archive SpotBugs, CheckStyle, PMD, or CPD warnings, respectively (only available for Maven projects).
These values can replace or amend the default configuration for the recordIssues
step of the https://github.com/jenkinsci/warnings-ng-plugin[Warnings NG Plugin].
See https://github.com/jenkinsci/warnings-ng-plugin/blob/master/doc/Documentation.md#configuration[Warnings NG Plugin documentation]
for a list of available configuration parameters.timeout
: (default: 60
) - the number of minutes for build timeout, cannot be bigger than 180, i.e. 3 hours.NOTE: The recordIssues
steps of the warnings plugin and the recordCoverage
steps of the coverage plugin run on the first platform/jdkVersion,jenkinsVersion combination only.
So in the example below it will run for linux
/jdk11
but not on jdk17
.
Usage:
=== buildPluginWithGradle()
Builds a Jenkins plugin using Gradle. The implementation follows the standard build/test/archive pattern. The method targets compatibility with link:https://github.com/jenkinsci/gradle-jpi-plugin[Gradle JPI Plugin], and it may not work for other use-cases.
==== Optional arguments
repo
(default: null
inherit from Multibranch) - custom Git repository to check outfailFast
(default: true
) - instruct the build to fail fast when one of the configurations failplatforms
(default: ['linux', 'windows']
) - Labels matching platforms to
execute the steps against in paralleljdkVersions
(default: [8]
) - JDK version numbers, must match a version
number jdk tool installedconfigurations
: An alternative way to specify platforms
, jdkVersions
(that can not be combined
with any of them)
** Those options will run the build for all combinations of their values. While that is desirable in
many cases, configurations
permit to provide a specific combinations of label and java/jenkins versions to usetests
: (default: null
) - a map of parameters to run tests during the build
** skip
- If true
, skip all the tests.jacoco
: (default: null
) - a map of parameters to change the default configuration of the recordCoverage
step of the https://github.com/jenkinsci/code-coverage-api-plugin[Code Coverage Plugin]. This step is called after a plugin build to record the code coverage results of JaCoCo. See https://www.jenkins.io/doc/pipeline/steps/code-coverage-api/#recordcoverage-record-code-coverage-results[recordCoverage step documentation] for a list of available configuration parameters.spotbugs
, checkstyle
: (default: null
) - a map of parameters to archive SpotBugs or CheckStyle warnings, respectively.
These values can replace or amend the default configuration for the recordIssues
step of the https://github.com/jenkinsci/warnings-ng-plugin[Warnings NG Plugin].
See https://github.com/jenkinsci/warnings-ng-plugin/blob/master/doc/Documentation.md#configuration[Warnings NG Plugin documentation]
for a list of available configuration parameters.timeout
: (default: 60
) - the number of minutes for build timeout, cannot be bigger than 180, i.e. 3 hours.noIncrementals
: (default: false
) - de-activates incremental version publication.==== Limitations
Not all features of buildPlugin()
for Maven are supported in the gradle flow.
Examples of not supported features:
jenkinsVersion
for the build flow (as standalone arguments or as configurations
)=== infra.isTrusted()
Determine whether the Pipeline is executing in an internal "trusted" Jenkins environment
=== infra.ensureInNode(nodeLabels, body)
Ensures that the given code block is runs in a node with the specified labels
=== runBenchmarks
Runs JMH benchmarks and archives benchmark reports on highmem
nodes.
Supported parameters:
artifacts
::
(Optional) If artifacts
is not null, invokes archiveArtifacts
with the given string value.
==== Example
=== buildDockerAndPublishImage(imageName, config)
Lints, Builds, then publishes a docker image.
Adds a bunch of build args you can use in your docker image:
Supported parameters:
imageName
::
Name of the docker image to build
config
::
(Optional) map of extra flags
parallelDockerUpdatecli
with config
within buildDockerConfig

[source, groovy]== Contribute
=== Requirements
=== Testing a pull request
By adding @Library('pipeline-library@pull/<your-pr-number>/head') _
at the top of a Jenkinsfile from a repository built on one of the *.ci.jenkins.io instances, you can test your pipeline library pull request on ci.jenkins.io.
A repository is dedicated for these kind of tests: https://github.com/jenkinsci/jenkins-infra-test-plugin/
