/**
 * Adds an entry to the jeka-src classpath where this annotation is declared.
 * Typically, the annotated element is a KBean class from 'jeka/def' source directory.
 * But when used on a public field of type  KBean within a KBean class,
 * the annotated field is injected with an initialised KBean instance of the imported project.
 *
 * Example :
 * 

 * public class FatJarBuild extends KBean {
 *
 *     @JkInjectRunbase
 *     ProjectKBean projectKBean;
 *
 *     @JkInjectRunbase("../anotherJekaProject")
 *     private AClassicBuild sampleBuild;
 *
 *     ...
