Energy Systems - Building Energy Monitoring - Java
Published by sfeilmeier about 6 years ago

Common

Update all dependencies
Improve documentation in Antora and JavaDocs
Improve Gradle build:
- gradlew antora to build the Antora docs inside /build/www directory. 40df39dad57dd8dfa5c8bf54279ec401b4f4c7ff
- gradlew buildEdge to build an OpenEMS Edge fat-jar at /build/openems-edge.jar
