As of 17. Mar, 2020, this project has been deprecated. An updated and maintained version can be found at AdoptOpenJDK/install-jdk. This repository will remain available indefinitely, but switching is strongly recommended as used services might not.

install-jdk

An action to download and install JDKs for use in workflows.

This action is based on the actions/setup-java action by GitHub which works perfectly fine for simple workflows but does not scale and lacks configurability.

JDKs are downloaded from AdoptOpenJDK.

Usage

See action.yml

Basic

steps:
- uses: actions/checkout@v1
- uses: TheMrMilchmann/install-jdk@v1
 with:
   version: '13'
   architecture: x64

Multiple JDKs

Some projects may require multiple JDK versions to build. install-jdk supports installing JDKs to one (or more) given target environment variables.

- uses: actions/checkout@v1
- uses: TheMrMilchmann/install-jdk@v1
 with:
   version: '8'
   architecture: x64
- uses: TheMrMilchmann/install-jdk@v1
 with:
   version: '13'
   architecture: x64
   targets: 'JDK_13'

Configuration:

Parameter	Default
version
architecture	x64
source
archiveExtension
targets	JAVA_HOME

version

The Java version to install a JDK for. (Supported values are: 1.8, 8, 9, 10, 11, 12, 13, ...)

By default, this action will try to install the latest JDK release for the specified version from AdoptOpenJDK. Alternatively, a source can be specified explicitly.

The version key should be set accordingly for custom downloads since it is used to cache JDKs which are used multiple times during the workflow.

architecture

The target architecture of the JDK to install.

Defaults to x64.

source

A custom source location of a JDK. This might be either a local directory, a compressed file, or an url.

archiveExtension

The extension of the JDK archive. (Supported values are: .zip, .tar, .7z)

Specifying this property is required when a custom source is set.

targets

A semicolon-separated list of environment variables which will be set up to point to the installation directory of the JDK.

By default, this is set to JAVA_HOME. Keep in mind that this is overwritten when specifying targets explicitly. Thus, if you want to make a JDK available from - say - JDK_X and JAVA_HOME, you would need to specify:

targets: 'JDK_X;JAVA_HOME'
