How to build Java packages with Gitlab CI.

What are Java packages?

Java is a general-purpose, concurrent, class-based, object-oriented programming language specifically designed to have as few implementation dependencies as possible. It lets application developers 'write once, run anywhere' (WORA), meaning that coders can write a single application and compile it on many platforms without rewriting it. These targeted applications include enterprise software systems, applets, browser plugins, J2ME apps, and other applications that have already driven the popularity of Java technology on the server and the embedded platform.

What is Gitlab CI?

GitLab CI/CD helps you automatically build, test, deploy, and monitor your code. Run tests before every merge (Continuous Integration) to make sure the code is continuously strong. Set up your git repository to automatically trigger builds when you push commits (Continuous Delivery). Integrate behavior-driven development (BDD) frameworks like Cucumber or jBehave into your workflow to write more comprehensive automated acceptance tests that communicate functionality more effectively than plain unit tests.

Packagecloud works with all kinds of packages, not only Java packages. As well, you can integrate with all kinds of CI/CD tools, not only Gitlab CI.
