⁠OpenShift S2I Builder for Java Docker image

This Source-to-Image Builder let's you create projects targetting Java OpenJDK 8 and built with:

• gradle
• maven

This builder/runtime s2i image can be used with SpringBoot, Vert.X, Wildfly Swarm, DropWizard and many other microservices frameworks.

⁠BUILD ENV Options

• GRADLE_ARGS: Allows you to specify options to pass to gradle (Default: build)
• MAVEN_ARGS: Allows you to specify options to pass to maven (Default: install)
• BUILD_ARGS: Allows you to specify options to pass to gradle or maven (will be replaced by GRADLE_ARGS or MAVEN_ARGS)
• ARTIFACT_DIR: Path to find where the jar files are created when build.

⁠RUN ENV Options
