Conflicting key types 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, they both define a key dockerCmd with different types (String and Seq[String] respectively), so loading the project fails:

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 modifying the plugins to agree on the types?

Answer 1

See Plugins Best Practices:

Key naming convention: Use prefix

Sometimes, you need a new key, because there is no existing sbt key. In this case, use a plugin-specific prefix.
