openHAB Core

This project contains core bundles of the openHAB runtime.

Building and running the project is fairly easy if you follow the steps detailed below.

Please note that openHAB Core is not a product itself, but a framework to build solutions on top. It is picked up by the main openHAB distribution.

This means that what you build is primarily an artifact repository of OSGi bundles that can be used within smart home products.

1. Prerequisites

The build infrastructure is based on Maven. If you know Maven already then there won't be any surprises for you. If you have not worked with Maven yet, just follow the instructions and everything will miraculously work ;-)

What you need before you start:

• Java SE Development Kit 21
• Maven 3 from https://maven.apache.org/download.html

Make sure that the mvn command is available on your path

2. Checkout

Checkout the source code from GitHub, e.g. by running:

git clone https://github.com/openhab/openhab-core.git

3. Building with Maven

To build this project from the sources, Maven takes care of everything:

• set MAVEN_OPTS to -Xms512m -Xmx1024m
• change into the openhab-core directory (cd openhab-core)
• run mvn clean install to compile and package all sources

If there are tests that are failing occasionally on your local build, run mvn -DskipTests=true clean install instead to skip them.
