Key type conflict in different subprojects

Question

I have a project with two subprojects. In one I want to use sbt-docker , in the other, sbt-native-packager . However, both of them define the dockerCmd key with different types ( String and Seq[String] respectively), therefore the project is not loaded:

 java.lang.RuntimeException: Some keys were defined with the same name but different types: 'dockerCmd' (scala.collection.Seq[java.lang.String], java.lang.String) 

Is there a way around this easier than changing plugins for type matching?
