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: 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:

url, if source starts with "http://" or "https://",
file, if source resembles a valid local file path and the file exists,
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)
