install-jdk

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

JDKs are downloaded from AdoptOpenJDK.

Usage

See action.yml

Basic

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

Configuration:

Parameter	Default
version
architecture	x64
source	releases
sourceType
archiveBasePath	/Contents/Home/ (macOS only)
useArchiveBasePath	true
archiveExtension
targets	JAVA_HOME
impl	hotspot

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 for a JDK. (See sourceType for supported values.)

sourceType

The type of the source parameter. Supported source types are:

• url - HTTP and HTTPS URL sources
• file - local directories, or compressed archives
• buildType - AdoptOpenJDK build types ("nightly", or "releases".)

The parameter may be set to empty, to automatically infer the type. The inferred type is:

1. url, if source starts with "http://" or "https://",
2. file, if source resembles a valid local file path and the file exists,
3. or buildType otherwise.

archiveBasePath

install-jdk expects a single top-level folder in archive packages. This parameter may be used to specify the subdirectory of said folder in which the JDK resides. This must be empty, or a /-separated path.

By default, this parameter is set to /Contents/Home/ on macOS only to support OpenJDK builds from Oracle, and OpenJDK and OpenJ9 builds from AdoptOpenJDK out of the box.

When using builds from other sources, it may be necessary to disable use of this parameter since the action cannot differentiate between empty and unspecified parameters. (See useArchiveBasePath.)

useArchiveBasePath

Disables use of the archiveBasePath parameter. This must be a boolean value.

Build archives from custom other may have different directory structures for which the default configuration would fail. E.g.: For Azul's Zulu builds it should be set to false (useArchiveBasePath : 'false').

archiveExtension

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

Specifying this parameter 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'

impl

JVM implementation. (Supported values are: hotspot, openj9)
