Android build fails with UnityException: JDK not found on Windows

[camnewnham]

Hi, thanks for making this action public. It's very helpful.

After using the action kuler90/setup-unity@v1 with Android on a windows-latest (windows-2022) image on github actions I get the following in the Unity build log (and the build fails):

DisplayProgressbar: Checking prerequisites
Android PostProcess task "Checking prerequisites" took 4.386 ms
DisplayProgressbar: Detect Java Development Kit (JDK)
UnityException: JDK not found
Java Development Kit (JDK) directory is not set or invalid. Please, fix it in Edit / Unity -> Preferences -> External Tools
UnityEditor.BuildPipeline:BuildPlayerInternalNoCheck(String[], String, String, BuildTargetGroup, BuildTarget, Int32, BuildOptions, String[], Boolean)
UnityEditor.BuildPipeline:BuildPlayerInternal(String[], String, String, BuildTargetGroup, BuildTarget, Int32, BuildOptions, String[])
UnityEditor.BuildPipeline:BuildPlayer(String[], String, String, BuildTargetGroup, BuildTarget, Int32, BuildOptions, String[])
UnityEditor.BuildPipeline:BuildPlayer(BuildPlayerOptions)

The setup-unity log looks normal:

Some discussions here that mention this was an issue (on ubuntu however...) in an older hub version when installing headless: game-ci/unity-builder#489

I've worked around this by using powershell based on the js code from this repo

      - name: Install Unity
        id: install_unity
        run: |
          $match = [regex]::match((Get-Content -Path ProjectSettings\ProjectVersion.txt | Out-String), 'm_EditorVersionWithRevision: (?<version>[^\s]+) \((?<changeset>[^\)]+)\)')
          $unityVersion = $match.groups["version"].Value
          $unityChangeset = $match.groups["changeset"].Value

          curl --output installer.exe "https://public-cdn.cloud.unity3d.com/hub/prod/UnityHubSetup.exe"
          Invoke-Expression "& '.\installer.exe' /S | Out-Default"
          Invoke-Expression "& 'C:/Program Files/Unity Hub/Unity Hub.exe' -- --headless install --version $unityVersion --changeset $unityChangeset | Out-Default"
          Invoke-Expression "& 'C:/Program Files/Unity Hub/Unity Hub.exe' -- --headless install-modules --version $unityVersion --module $env:UNITY_MODULES --childModules | Out-Default"
      
          echo "UNITY_PATH=$("C:\Program Files\Unity\Hub\Editor\$unityVersion\Editor\Unity.exe")" >> $env:GITHUB_ENV
          ```
