Helidon: Java Libraries for Microservices

Project Helidon is a set of Java Libraries for writing microservices. Helidon supports two programming models:

  • Helidon MP: MicroProfile 1.1 plus Health Check and Metrics
  • Helidon SE: a small, functional style API

In either case your application is just a Java SE program.

Documentation

Latest documentation and javadocs are available at https://helidon.io/docs/latest.

Get Started

See Getting Started at https://helidon.io.

Downloads / Accessing Binaries

There are no Helidon downloads. Just use our Maven releases (GroupID io.helidon). See Getting Started at https://helidon.io.

Build

You can build Helidon using JDK 8 or 9. 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/.
