Run `mvn clean package -Prelease,docker -Dmaven.javadoc.skip=true -Dmaven.test.skip=true` from a fresh ShenYu checkout to reproduce the failure. Inspect the Maven release and Docker build configuration involved in that command; done means the command completes successfully and builds the Docker image.
