Fabric8 Docker Maven plugin not working for compose.yml on Multi module project - maven

Question

I trying to use Fabric8 docker-maven-plugin, though I was successful in configuring plugin for individual module and run docker:build docker:start Maven goal without using docker-compose.yml, however I needed externalize ports and link the different module, hence I intended to use docker-compose.yml. Below is my project structure.
--kp-parent
|
--- docker-compose.yml
--- pom.xml
|
---- rest1
| |
| -- .maven-dockerignore
| -- pom.xml
| -- Dockerfile
---- rest2
| |
| -- .maven-dockerignore
| -- pom.xml
| -- Dockerfile
Here are my configurations
Dockerfile[both rest1 and rest2 use identical file except the different port]
FROM openjdk:8-jdk-alpine
MAINTAINER 'Karthik Prasad'
ARG IMAGE_VERSION
ARG JAR_FILE
ENV JAVA_OPTS=""
LABEL version = IMAGE_VERSION
VOLUME /tmp
ADD /maven/${JAR_FILE}.jar app.jar
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
EXPOSE 8000
.maven-dockerignore[In both child modules identical file]
target/**
pom.xml [Both rest1 and rest2 pom files are same except the artifcatid and name of the project]

And finally docker-compose.yml
version: '2'
services:
rest1:
image: kp-ms/rest1:0.0.1-SNAPSHOT
ports:
- 8000:8000
rest2:
image: kp-ms/rest2:0.0.1-SNAPSHOT
ports:
- 8001:8001
links:
- rest1
When I run the docker:build docker:start I get below error.
[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.22.1:start (default-cli) on project rest1: I/O Error: Unable to pull 'kp-ms/rest2:0.0.1-SNAPSHOT' : repository kp-ms/rest2 not found: does not exist or no pull access (Not Found: 404) -> [Help 1]
[ERROR]
However If I remove rest2 section in docker-compose.yml, build goes fine and I'm able to find the container start successfully.
Another problem I noticed is that even if do not give image name in docker-compose.yml build fails with error image is null. However I'm not sure why I need to provide image can't the plugin map from plugin configuration as I had provided alias. As you can notice I'm trying to generate image name dynamically.
