Building containerized applications can require complex configurations in development environments and on build agents. If you're building a Java application and use Docker, you might consider using Google's Jib. Jib is an open-source plugin supporting both Maven and Gradle. The Jib plugin uses information from your build config to build your application directly as a Docker image without requiring a Dockerfile or Docker daemon. Jib optimizes around image layering, promising to speed up subsequent builds.
