0.4.0 version doesn't work anymore

Foojay Toolchains Plugin

The org.gradle.toolchains.foojay-resolver plugin provides a repository for downloading JVMs. It is based on the foojay DiscoAPI. Requires Gradle 7.6 or later to work.

TAKE HEED! As opposed to most of the Gradle plugins, which are Project plugins and must be applied in build.gradle[.kts] files, this is a SETTINGS PLUGIN and must be applied in settings.gradle[.kts] files.

Usage

To make use of the plugin add following to your settings.gradle[.kts] file.

Kotlin DSL

// settings.gradle.kts
plugins {
    id("org.gradle.toolchains.foojay-resolver-convention") version "0.8.0"
}

Groovy DSL

// settings.gradle
plugins {
    id("org.gradle.toolchains.foojay-resolver-convention") version "0.8.0"
}

This is a convention plugin meant to simplify configuration. What it does is equivalent to applying the base plugin and some extra configuration:

Kotlin DSL

// settings.gradle.kts
plugins {
    id("org.gradle.toolchains.foojay-resolver") version "0.8.0"
}

toolchainManagement {
    jvm {
        javaRepositories {
            repository("foojay") {
                resolverClass.set(org.gradle.toolchains.foojay.FoojayToolchainResolver::class.java)
            }
        }
    }
}

Groovy DSL

// settings.gradle
plugins {
    id("org.gradle.toolchains.foojay-resolver") version "0.8.0"
}

toolchainManagement {
    jvm {
        javaRepositories {
            repository("foojay") {
                resolverClass = org.gradle.toolchains.foojay.FoojayToolchainResolver
            }
        }
    }
}

Feel free to use either approach.

For further information about using Toolchain Download Repositories consult the Gradle Manual.

Matching Toolchain Specifications

The main thing the plugin does is to match Gradle's toolchain specifications to foojay DiscoAPI distributions and packages.

Vendors

There is mostly a 1-to-1 relationship between the DiscoAPI's distributions and Gradle vendors. The plugin works with the following mapping:

Gradle JVM Vendor	Foojay Distribution
ADOPTIUM	Temurin
ADOPTOPENJDK	AOJ
AMAZON	Corretto
APPLE	-
AZUL	Zulu
BELLSOFT	Liberica
GRAAL_VM	Graal VM CE 8/11/16/17/19
HEWLETT_PACKARD	-
IBM	Semeru
IBM_SEMERU	Semeru
MICROSOFT	Microsoft
ORACLE	Oracle OpenJDK
SAP	SAP Machine

To note: Not all Gradle vendors have an equivalent DiscoAPI distribution, empty cells indicate that no toolchain will be provisioned. If no vendor is specified, distributions are iterated in the order they are provided by the DiscoAPI, and the first one that has a compatible installation package available is selected. The exception to the Foojay ordering of distributions is that "Temurin" (ADOPTIUM) and then "AOJ" (ADOPTOPENJDK) come first, due to the history of the auto-provisioning feature in Gradle, specifically that AdoptOpenJDK/Adoptium have been the default sources for downloading JVMs.

Implementations

When specifying toolchains Gradle distinguishes between J9 JVMs and VENDOR_SPECIFIC ones (ie. any other). What this criteria does in the plugin is to influence the Vendor-to-Distribution matching table. VENDOR_SPECIFICATION doesn't change it at all, while J9 alter it like this:

Gradle JVM Vendor	Foojay Distribution
<no vendor specified>	Semeru
ADOPTIUM	-
ADOPTOPENJDK	AOJ OpenJ9
AMAZON	-
APPLE	-
AZUL	-
BELLSOFT	-
GRAAL_VM	-
HEWLETT_PACKARD	-
IBM	Semeru
IBM_SEMERU	Semeru
MICROSOFT	-
ORACLE	-
SAP	-

Empty cells indicate that no toolchain will be provisioned

Versions

Once the vendor and the implementation values of the toolchain spec have been used to select a DiscoAPI distribution, a specific package of that distribution needs to be picked by the plugin, in order for it to obtain a download link. The inputs it uses to do this are:

the major Java version number for the spec
the operating system running the build that made the request
the CPU architecture of the system running the build that made the request

Additional criteria used for selection:

for each major version number only packages having the latest minor version will be considered
only packages containing an archive of a format known to Gradle will be considered (zip, tar, tgz)
JDKs have priority over JREs

	assertDownloadUri(
	"https://api.foojay.io/disco/v3.0/ids/c2457a42e8aa37d56d4564214dff9a85/redirect",
	8, any(), false, OperatingSystem.MAC_OS, Architecture.AARCH64
	) // zulu8.74.0.17-ca-fx-jdk8.0.392-macosx_aarch64.tar.gz
