The code is written mostly in Java (currently, source level 1.8). IntelliJ IDEA is recommended for coding (Community Edition is fine): Import as Gradle project.

Projects supports building for Linux, Windows and Mac OS X.

Use Gradle for building a package for your desired platform:

./gradlew or make in the project dir for the list of available targets.

./gradlew current would build the app for your current platform

The resulting binaries will be put into the build/libs directory. Run jar files with java -jar <jar-file>.

Deb and rpm packages can only be built on Linux (tested on Ubuntu). Building of Windows installer can be done on Linux as well.

./gradlew all will build packages for all OS (tested on Ubuntu only, see dependencies below).

On Ubuntu install the following packages:

sudo apt install openjdk-11-jdk rpm fakeroot wine-stable

Note: wine is needed for building of Windows installer.

Install OpenJDK on other platforms as you usually do it.
