Issue with building Java kotlin build using gha runner set

[upenderbattu]

Hi,
I am currently running GitHub Actions on a self-hosted runner using the ghcr.io/actions/actions-runner:latest image. However, I am encountering an issue with building a Java-Kotlin project on this setup.

The same build works perfectly on GitHub-hosted runners, and both environments are based on Ubuntu. I have ensured that all required packages are installed on the self-hosted runner, but the build continues to fail.

Below is the error I am encountering:

* What went wrong:
Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.
A problem occurred configuring root project 'api-docs'.
> One of setGitDir or setWorkTree must be called.

code snippet:

 - name: build-kotlin
      working-directory: api-docs
      run: |
        ls -al
        echo "running wrapper"
        sudo apt-get update
        sudo apt-get install -y curl gradle maven unzip zip        
        curl -s "https://get.sdkman.io" | bash
        source "$HOME/.sdkman/bin/sdkman-init.sh"
        sdk install kotlin
        gradle --version
        kotlinc -version
        echo "listing gradle settings"
        
        cat gradle.properties
        echo "Running build now"
        
        ./gradlew -D"org.gradle.jvmargs=-Xmx4096m -XX:MaxMetaspaceSize=1024m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8" clean build --scan
