fabric8-maven-plugin - Generator for Dropwizard app (java-exec?)

Question

I'm new to fabric8-maven-plugin.

I have a Dropwizard fat jar which I'd like to containerize for OpenShift/okd. It seems the recommended way would invoke the java-exec generator: http://maven.fabric8.io/#generator-java-exec

Problem is that Dropwizard apps have a config file argument that must be provided, but I'm not sure how to instruct the generator to do so.

Correct invocation should be:

java -jar hello-world-0.0.1-SNAPSHOT.jar server hello-world.yml

The generator does the following, which is missing arguments:

java -jar hello-world-0.0.1-SNAPSHOT.jar

Answer 1

The following seems to be the simplest approach:

Use the exec-maven-plugin in your build configuration. Supply the needed arguments: one for the command and another for the configuration file location.

The following example is a random search result: https://github.com/christian-posta/microservices-by-example-source/blob/master/hola-dropwizard/pom.xml#L103-L114.

It seems to implement the approach described here: https://www.oreilly.com/ideas/microservices-for-java-developers/page/3/dropwizard-for-microservices#chapter-3-dropwizard-for-microservices
