   I cannot assign JAVA_HOME variable to switch Java versions. It shows empty value. How it should be done?

         - name: Set up multiple JDKs
           uses: actions/setup-java@v4
           with:
             distribution: 'corretto'
             java-version: |
               21
               11
         - name: Some java work that requires JAVA 21
           env:
             JAVA_HOME: ${{ env.JAVA_HOME_21_x64 }}
           run: java HelloWorldApp.java

   This is a usage question, so answering and closing it here. To install multiple JDKs and have a later step use a specific one, pass a multi-line java-version — setup-java installs each and exports JAVA_HOME_<major>_<arch> for every version (the last one becomes the active JAVA_HOME/PATH):

   steps:
     - uses: actions/setup-java@v4
       with:
         distribution: 'temurin'
         java-version: |
           8
           11
           17
     - name: Use Java 11 explicitly
       run: \$JAVA_HOME_11_X64/bin/java -version
     - name: Default (last installed = 17)
       run: java -version

   See the docs: https://github.com/actions/setup-java?tab=readme-ov-file#install-multiple-jdks

   Note: this installs multiple versions of one distribution. Installing multiple distributions in one step is a separate feature request, now tracked in #1049. For questions, the GitHub Actions community discussions are also a good venue.
