|  | # Switching to V2
 | ||
|  | ## Java distribution
 | ||
|  | The major breaking change in V2 is the new mandatory `distribution` input. This field should be specified with one of supported distributions. See [Supported distributions](../README.md#Supported-distributions) for a list of available options.   | ||
|  | Use the `zulu` keyword if you would like to continue using the same distribution as in V1. | ||
|  | ```yaml | ||
|  | steps: | ||
|  | - uses: actions/checkout@v2 | ||
|  | - uses: actions/setup-java@v2-preview | ||
|  |   with: | ||
|  |     distribution: 'zulu' | ||
|  |     java-version: '11' | ||
|  |     java-package: jdk # optional (jdk or jre) - defaults to jdk | ||
|  | - run: java -cp java HelloWorldApp | ||
|  | ``` | ||
|  | 
 | ||
|  | **General recommendation** — configure CI with the same distribution that is used on your local dev machine. | ||
|  | 
 | ||
|  | ## Installing custom Java distribution from local file
 | ||
|  | Since the `distribution` input is required in V2, you should specify it using `jdkFile` to continue installing Java from a local file on the runner | ||
|  | ```yaml | ||
|  | steps: | ||
|  | - run: | | ||
|  |     download_url="https://github.com/AdoptOpenJDK/openjdk11-binaries/releases/download/jdk-11.0.10%2B9/OpenJDK11U-jdk_x64_linux_hotspot_11.0.10_9.tar.gz" | ||
|  |     wget -O $RUNNER_TEMP/java_package.tar.gz $download_url | ||
|  | - uses: actions/setup-java@v2-preview | ||
|  |   with: | ||
|  |     distribution: 'jdkFile' | ||
|  |     jdkFile: ${{ runner.temp }}/java_package.tar.gz | ||
|  |     java-version: '11.0.0' | ||
|  |     architecture: x64 | ||
|  | ``` | ||
|  | 
 | ||
|  | ## Dropping legacy Java version syntax 1.x
 | ||
|  | V1 supported legacy Java syntax such as `1.8` (same as `8`) and `1.8.0.212` (same as `8.0.212`).  | ||
|  | V2 dropped support for legacy syntax so workflows should be updated accordingly.  |
