Under The Hood

Jeka consists of a single zero-dependency JAR file, along with two shell scripts (one Powershell script for Windows and one Bash script for Linux/macOS).

Inside the Jeka JAR

The Jeka JAR is structured as follows:

  • dev.jeka.core.tool package:

    Contains classes for running Java externally, including the dev.jeka.core.tool.Main class and the component model.

  • dev.jeka.core.tool.builtin package:

    Contains KBeans bundled with JeKa, as ProjectKBean, DockerKBean or NativeKBean.

  • dev.jeka.core.api package:

Includes libraries for building projects. These classes can be easily used outside Jeka and embedded in your product.
