Building from Source

Prerequisites

• Java 25 (see https://sdkman.io/ for installing java locally)
• Git
• Docker and Docker-Compose
• Your favorite IDE

Building Jikkou

We use Maven Wrapper to build our project. The simplest way to get started is:

For building distribution files.

$ ./mvnw clean package -Pdist -DskipTests

Alternatively, we also use Make to package and build the Docker image for Jikkou:

$ make

Running tests

For running all tests and checks:

$ ./mvnw clean verify

Code Format

This project uses the Maven plugin Spotless to format all Java classes and to apply some code quality checks.

Bugs & Security

This project uses the Maven plugin SpotBugs and FindSecBugs to run some static analysis to look for bugs in Java code.

Reported bugs can be analysed using SpotBugs GUI:

$ ./mvnw spotbugs:gui
