JAVA_HOME environment variable missing /bin at the end in ubuntu github actions runner

I am trying to run an application that needs Java as a prerequisite on a github actions runner. My yaml script is like:

steps:
  .
  .
  - name: Setup Java
    uses: actions/setup-java@v2
    with:
      distribution: 'adopt'
      java-version: '21'
  .
  .
  - name: Step that needs Java
    uses: ...
    with:
      ...

The Java setup goes fine, but the step that needs Java fails with an error saying
ERROR: The JAVA_HOME environment variable is not defined correctly. JAVA_HOME is set to /opt/hostedtoolcache/Java_Adopt_jdk/21.0.4-7.0.LTS/x64 and it does not exist.

The correct path is /opt/hostedtoolcache/Java_Adopt_jdk/21.0.4-7.0.LTS/x64/bin What do I do to append /bin to the end of JAVA_HOME?

    Your setup is correct. JAVA_HOME is also correct. If you run just the setup action actions/setup-java@v2, java is setup correctly and $JAVA_HOME/bin is in the PATH.

    The issue is most likely with the steps that follow java setup in your workflow.

    This workflow proves it:

    name: java

on:
  workflow_dispatch

jobs:
  java:
    runs-on: ubuntu-latest
    steps:
    - name: Setup Java
      uses: actions/setup-java@v2
      with:
        distribution: 'adopt'
        java-version: '21'

    - name: Show java
      run: |
        echo $JAVA_HOME
        echo $PATH
        java -version

    The output of the "Show java" step is like this:

    /opt/hostedtoolcache/Java_Adopt_jdk/21.0.4-7.0.LTS/x64

/opt/hostedtoolcache/Java_Adopt_jdk/21.0.4-7.0.LTS/x64/bin:/snap/bin:/home/runner/.local/bin:/opt/pipx_bin:/home/runner/.cargo/bin:/home/runner/.config/composer/vendor/bin:/usr/local/.ghcup/bin:/home/runner/.dotnet/tools:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

       uses: actions/setup-java@v4
       with:
        java-version: '17'
        distribution: 'temurin'
   #step that needs java 
     - name: Use oxr463/setup-leiningen 
       uses: oxr463/[email protected]
       with:
        exec: |
            lein uberjar && 
            cp "$(find . -name '*.jar')" .
