Jenkins pipeline files for building OpenJDK

Eclipse Adoptium makes use of these scripts to build binaries on the build farm at https://ci.adoptopenjdk.net

Repository contents

This repository contains several useful scripts in order to build OpenJDK personally or at build farm scale.

1. The docs folder contains images and utility scripts to produce up to date documentation.
2. The pipelines folder contains the Groovy pipeline scripts for Jenkins (e.g. build | test | checksum | release).
3. The tools folder contains pipelines/ analysis scripts that deliever success/failure trends and build scripts for code-tool dependancies for the build and test process (e.g. asmtools | jcov | jtharness | jtreg | sigtest).

Configuration Files

The pipelines/jobs/configurations directory contains two categories of configuration files that our jenkins pipelines use (Nicknamed #Build Configs and #Nightly Configs for short).

To ensure both configurations are not overridden in a race condition scenario by another job, the job generators ensure they remain in the sync with the repository.

Generally, any new parameters/configurations that effect the jenkins environment directly should be implemented here. If this is not the case, it would likely be better placed in temurin-build/platform-specific-configurations (for OS or make-adopt-build-farm.sh specific use cases) or temurin-build/build.sh (for anyone, including end users and jenkins pipelines).

Build

The build config files are the ones that follow the format jdkxx(u)_pipeline_config.groovy with xx being the version number and an optional u if the Java source code is pulled from an update repository. Each is a groovy class with a single Map<String, Map<String, ?>> property containing node labels, tests and other jenkins parameters/constants that are crucial for allowing different parts of the build pipeline to mesh together.

Each architecture/platform has it's own entry similar to the one below (for JDK8 x64 mac builds). The pipelines use the parent map key (e.g. x64Mac) to retrieve the data. See #Data Fields for the currently available fields you can utilise.

x64Mac        : [
    os                   : 'mac',
    arch                 : 'x64',
    additionalNodeLabels : [
            temurin  : 'macos10.14',
            corretto : 'build-macstadium-macos1010-1',
            openj9   : 'macos10.14'
    ],
    test                 : 'default'
]

Data fields

NOTE: When the type field implies a map, the String key of the inner map is the variant for that field. E.g:

                additionalNodeLabels : [
                        temurin : 'xlc13&&aix710',
                        openj9 :  'xlc13&&aix715'
                ],

Name	Required?	Type	Description
os	✅	String	Operating system tag that will identify the job on jenkins and determine which platforms configs to pull from temurin-build. E.g. windows, solaris
arch	✅	String	Architecture tag that will identify the job on jenkins and determine which build params to use. E.g. x64, sparcv9, x86-32
test	❌	String OR Map<String, List> OR Map<String, List or Map<String, List>>	Case one: Tests to run against the binary after the build has completed. A default tag indicates that you want to run whatever the default test nightly/release list is. Case two: You can also specify your own list for that particular platform (not variant). Case three: Or you can even specify the list for that particular platform per variant. The list could be specific one sanity.openjdk or default (similar to the first case) or a map per nightly or release (similar to case two).
testDynamic	❌	Boolean OR Map<String, ?>	PARALLEL=Dynamic parameter setting. False : no Parallel. Or you can set the parameters with or without variant.
dockerImage	❌	String OR Map<String, String>	Builds the JDK inside a docker container. Should be a DockerHub identifier to pull from in case dockerFile is not specified. E.g. adoptopenjdk/centos6_build_image
dockerFile	❌	String OR Map<String, String>	Builds the JDK inside a docker container using the locally stored image file. Used in conjunction with dockerImage to specify a particular variant to build or pull. E.g. pipelines/build/dockerFiles/cuda.dockerfile
dockerNode	❌	String OR Map<String, String>	Specifies a specific jenkins docker node label to shift into to build the JDK. E.g. sw.config.uid1000
dockerRegistry	❌	String OR Map<String, String>	Used for Docker login when pulling dockerImage from a custom Docker registry. Used in conjunction with dockerImage. Default (blank) will be DockerHub. Must also use dockerCredential.
dockerCredential	❌	String OR Map<String, String>	Used for Docker login when pulling a dockerImage. Value is the Jenkins credential ID for the username and password of the dockerRegistry. Used in conjunction with dockerImage. Can use with custom dockerRegistry or default DockerHub. Must use this if using a non-default registry.
additionalNodeLabels	❌	String OR Map<String, String>	Appended to the default constructed jenkins node label (often used to lock variants or build configs to specific machines). Jenkins will additionally search for a node with this tag as well as the default node label. E.g. build-macstadium-macos1010-1, macos10.14
additionalTestLabels	❌	String OR Map<String, String>	Used by aqa-tests to lock specific tests to specific machine nodes (in the same manner as additionalNodeLabels) E.g. !(centos6||rhel6), dragonwell
configureArgs	❌	String OR Map<String, String>	Configuration arguments that will ultimately be passed to OpenJDK's ./configure E.g. --enable-unlimited-crypto --with-jvm-variants=server --with-zlib=system
buildArgs	❌	String OR Map<String, String>	Build arguments that will ultimately be passed to temurin-build's ./makejdk-any-platform.sh script E.g. --enable-unlimited-crypto --with-jvm-variants=server --with-zlib=system
additionalFileNameTag	❌	String	Commonly used when building large heap versions of the binary, this tag will also be included in the jenkins job name and binary filename. Include this parameter if you have an "extra" variant that requires a different tagname E.g. linuxXL
crossCompile	❌	String OR Map<String, String>	Used when building on a cross compiled system, informing jenkins to treat it differently when retrieving the version and producing the binary. This value is also used to create the jenkins node label alongside the arch (similarly to additionalNodeLabels) E.g. x64
bootJDK	❌	String	JDK version number to specify to temurin-build's make-adopt-build-farm.sh script, informing it to utilise a predefined location of a boot jdk E.g. 8, 11
platformSpecificConfigPath	❌	String	temurin-build repository path to pull the operating system configurations from inside temurin-build's set-platform-specific-configurations.sh. Do not include the repository name or branch as this is prepended automatically. E.g. pipelines/TestLocation/platform-specific-configurations
codebuild	❌	Boolean	Setting this field will tell jenkins to spin up an Azure or AWS cloud machine, allowing the build to retrieve a machine not normally available on the Jenkins server. It does this by appending a codebuild flag to the jenkins label.
cleanWorkspaceAfterBuild	❌	Boolean	Setting this field will tell jenkins to clean down the workspace after the build has completed. Particularly useful for AIX where disk space can be limited.

Nightly

The nightly config files are the ones that follow the format jdkxx(u).groovy with xx being the version number and an optional u if the Java source code is pulled from an update repository. Each is a simple groovy script that's contents can be loaded in and accessed by another script.

targetConfigurations

A single Map<String, Map<String, String>> variable containing what platforms and variants will be run in the nightly builds and releases (by default, this can be altered in jenkins parameters before executing a user build). If you are creating your own nightly config, you will need to ensure the key values of the upper map are the same as the key values in the corresponding build config file.

targetConfigurations = [
        "x64Mac"        : [
                "temurin",
                "openj9"
        ],
        "x64Linux"      : [

                "temurin",
                "openj9"
        ],
        "s390xLinux"    : [
                "temurin",
                "openj9"
        ],
        "aarch64Linux"  : [
                "temurin",
                "openj9",
                "dragonwell"
        ],
        "arm32Linux"  : [

        ],
        "sparcv9Solaris": [
                "temurin"
        ]
]

disableJob

If this is present, the jenkins generators will still create the top-level pipeline and downstream jobs but will set them as disabled.

disableJob = true

triggerSchedule_nightly / triggerSchedule_weekly

Cron expression that defines when (and how often) nightly and weekly builds will be executed

triggerSchedule_nightly="TZ=UTC\n05 18 * * 1,3,5"
triggerSchedule_weekly="TZ=UTC\n05 12 * * 6"

weekly_release_scmReferences

Source control references (e.g. tags) to use in the weekly release builds

weekly_release_scmReferences = [
        "temurin"        : "jdk8u282-b07",
        "openj9"         : "v0.24.0-release",
        "corretto"       : "",
        "dragonwell"     : ""
]

Metadata

Alongside the built assets a metadata file will be created with info about the build. This will be a JSON document of the form:

{
    "vendor": "Eclipse Adoptium",
    "os": "mac",
    "arch": "x64",
    "variant": "openj9",
    "variant_version": {

        "security": "0",
        "tags": "m2"
    },
    "version": {
        "minor": 0,

    "sha256": "<shasum>",
    "full_version_output": "<output of java --version>",
    "configure_arguments": "<output of bash configure>"
}

The Metadata class is contained in the Metadata.groovy file and the Json is constructed and written in the openjdk_build_pipeline.groovy file.

It is worth noting the additional tags on the SemVer is the Adoptium build number.

Below are all of the keys contained in the metadata file and some example values that can be present.

---

• vendor: Example values: [Eclipse Adoptium, Alibaba, Huawei]

This tag is used to identify the vendor of the JDK being built, this value is set in the build.sh file and defaults to "Temurin".
