If you have something like the following where you accidentally list a plugin twice:

  dependencies:
    - "mvn://ca.vanzyl.concord.plugins:concord-k8s-plugin:0.0.1-SNAPSHOT"
    - "mvn://com.walmartlabs.concord.plugins:terraform-task:1.16.0"
    - "mvn://com.walmartlabs.concord.plugins:git:1.16.0"
    - "mvn://com.walmartlabs.concord.plugins:terraform-task:1.19.1"

We might want to warn or probably just fail fast and now allow it. Not sure how the plugin retriever or plugin classloader works but if can allow the random ordering of the plugins and how they are loaded it might lead to unexpected results.
