Project Helidon is a set of Java Libraries for writing microservices. Helidon supports two programming models:
- Helidon MP: MicroProfile 2.2
- Helidon SE: a small, functional style API
In either case your application is just a Java SE program.
Latest documentation and javadocs are available at https://helidon.io/docs/latest.
See Getting Started at https://helidon.io.
There are no Helidon downloads. Just use our Maven releases (GroupID io.helidon
).
See Getting Started at https://helidon.io.
You can build Helidon using JDK 8 or above. Building with 9+ results in jar files that are valid Java 9 modules containing Java 8 bytecodes.
You also need Maven. We recommend 3.5 or newer.
Building the documentation requires the dot
utility from Graphviz.
This is included in many Linux distributions. For other platforms
see https://www.graphviz.org/.
