setup-java

This action sets up a java environment for use in actions by:

optionally downloading and caching a version of java by version and adding to PATH. Downloads from Azul's Zulu distribution.
registering problem matchers for error output

Usage

See action.yml

Basic:

steps:
- uses: actions/checkout@v1
- uses: actions/setup-java@v1
  with:
    java-version: '9.0.4' // The JDK version to make available on the path. Takes a whole or semver JDK version, or 1.x syntax (e.g. 1.8 => JDK 8.x)
    architecture: x64 // (x64 or x86) - defaults to x64
- run: java -cp java HelloWorldApp

From local file:

steps:
- uses: actions/checkout@v1
- uses: actions/setup-java@v1

    architecture: x64
    jdkFile: <path to jdkFile> # Optional - jdkFile to install java from. Useful for versions not supported by Azul
- run: java -cp java HelloWorldApp

Matrix Testing:

    name: Java ${{ matrix.java }} sample
    steps:
      - uses: actions/checkout@master
