* Support mired units Mired are fairly common to describe the color temperature of lightbulbs (slightly less common than Kelvin), but are very useful for various calculations when adjusting the color temperature, as well as being necessary for various integerations that require mired units. This commit makes them a well-known unit (previously they were still usable, using "MK^-1"), as well as making them easier to work with on QuantityType. The hiccup is that Mireds aren't technically a Temperature dimension, because they're a reciprocal. So add a `inverse` method that delegates to javax.measure's same method, and then use it as necessary when doing unit conversions and comparisons. Unfortunately, because the dimension changes, the return value of a conversion won't necessarily be the same type, an additional method is added for callers that are willing to handle the change in dimension. This is implemented for all callers that can use it in core. Signed-off-by: Cody Cutrer <cody@cutrer.us> |

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 11
- 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_OPTSto-Xms512m -Xmx1024m - change into the openhab-core directory (
cd openhab-core) - run
mvn clean installto 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.
