The new Dockerfile has some problem?

Today I has update my gs-spring-boot-docker from yours, the file complete/Dockerfile has some changes and I encounter a problem.

When I build it on Jenkins, error like this...

Like you see.
I don't know why the ${DEPENDENCY} is /home/techgroup/docker/tmp/docker-builder059966854/target/dependency instead of target/dependency?
And this is a Spring-boot project, why the start script is ENTRYPOINT ["java","-cp","app:app/lib/*","hello.Application"] instead of ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]？
I am puzzled. Can you give me an answer? Thanks...

Sorry, I think I have find the reason because I annotated unpack...
