Java GitHub Actions Guidelines

What the Action does

In this Action, the package is built and published using Gradle. The package is deployed to the Nexus registry.

Notes

• It's recommended to use a Linux machine for building - jobs.<name>.runs-on property.
• For setting up Java environment, the action uses actions/setup-java@v1 action.
• It's essential to grant execute permission for gradlew with chmod +x gradlew.
• The release is triggered by the ./gradlew publish command.
• Secrets, keys, and tokens are stored in .env variables and secret properties.
