Description

A NullPointerException is thrown in a constructor of StartRetrieveArtifactEvent. It crashes in addMridAttributes of IvyEvent.java.

    protected void addMridAttributes(ModuleRevisionId mrid) {
        addModuleIdAttributes(mrid.getModuleId());  //NPE because mrid is null
       //...
    }

because IvyPublish$PublishArtifact.getModuleRevisionId() returns null no matter what in addArtifactAttributes method .

    protected void addArtifactAttributes(Artifact artifact) {
        addMridAttributes(artifact.getModuleRevisionId()); //artifact.getModuleRevisionId() returns null from  IvyPublish$PublishArtifact.getModuleRevisionId()
       //...
    }
