How to exclude dependency from classpath?

[Steve Orelse]

Assume that we have scala maven projects A and B. Project B has project A as a compile dependency. The goal is to test project B solely.

I have chosen to copy project A, making a mock-module A1, which has the same packages and API, but returns only valid objects without any logical processing.

Mock-project A1 is added to B's pom as a dependency for test scope.

I've managed to replace project A with mock-project A1 using this configuration for maven-surefire-plugin:

<configuration>
  <classpathDependencyExcludes>
    <classpathDependencyExclude>AProjectGroupId:AProjectArtifactId</classpathDependencyExclude>
  </classpathDependencyExcludes>
</configuration>

But I can't seem to find such configuration abilities for scalatest-maven-plugin.

So, how do I exclude dependency from classpath for tests in scalatest plugin? I'm guessing it also can be done in scala-maven-plugin for testCompile goal, but I still can't find how to configure it.
