¿Usando maven para convertir a TwelveMonkeys de Git en un proyecto de Eclipse java?

He importado TwelveMonkeys en eclipse desde git https clone, https://github.com/haraldk/TwelveMonkeys . Y me gustaría convertirlo en un proyecto de Java, para poder build los flasks. Después de la búsqueda, ejecutar "mvn eclipse: eclipse" en el directory raíz del proyecto debería hacer el truco? Pero tengo esto:

Ejecute mvn clean install primero en el package e instale las jarras en su repository local y luego mvn eclipse:eclipse funcionará.

El post de error es explícito: no puede encontrar la imageio-core:jar , porque aún no lo ha instalado.
