The Java platform used, prior to Java 9, was a build system riddled with duplicate code, redundancies, and other inefficiencies. The build system has been reworked for Java 9 based on the build-infra framework. In this context, infra is short for infrastructure. The overarching goal for JEP 284 was to upgrade the build system to one that was simplified. Specific goals included:
- Leverage existing build system
- Maintainable code
- Minimize duplicate code
- Simplification
- Support future enhancements
