+             As a workaround we shall use maven-antrun-plugin to copy the Dockerfile and apply filters to
+             replace the parameterized base-image version. The fabric8.io docker-maven-plugin shall use this filtered file
+             to build the image. After the image is built we perform a cleanup to remove the filtered file.-->
