Projectless Application

This repository demonstrates JeKa's ability to build, dockerize, and publish applications with zero build configurations or project structure.

The application is a simple command line tool displaying OpenJDK distributions managed by foojay-disco, by requesting the foojay-disco REST API.

Here, we don't create a project structure but rely solely on the JeKa scripting engine. Sources and tests are all located in the jeka-src directory, which allows declaring dependencies directly in Java code.

By convention, the _dev package (and its sub-packages) contains code and dependencies that are excluded from the production JAR.

This structure is suitable for small to medium-sized applications but can be trivially moved to a project structure later on.

Note:
This application can be easily moved into a plain project structure without requiring build configuration (only dependencies need to be externalized in a dependency.txt file).
