I just released mapjfx version 2.13.0, it will be available in maven central:

  <dependency>
    <groupId>com.sothawo</groupId>
    <artifactId>mapjfx</artifactId>
    <version>2.13.0</version>
  </dependency>

I switched back to use Java 11 (LTS) as SceneBuilder is only available for Java 11 (https://gluonhq.com/products/scene-builder/) and libraries built with version 12 or 13 cannot be used in SceneBuilder 11.
