To do a clean build, issue the following command:

$ ./gradlew clean build

This runs the unit tests and compiles a new kse.jar into build/libs. You can then update an existing KSE installation by replacing its kse.jar with this one.

The build.gradle file contains further instructions for building the platform specific distribution packages. In a nutshell:

For the ZIP package:

$ ./gradlew zip 

For the Windows installer:

$ ./gradlew nsis

For the MacOS application:

$ ./gradlew appbundler
