Executed NoClassDefFoundError tests in SBT with plugin with plugins

I have an SBT project with a structure like here: https://orrsella.com/2014/09/24/integration-and-end-to-end-test-configurations-in-sbt-for-scala-java-projects/ ... It includes the standard main and test directories and additionally it and e2e . There is also a " test-all" task that runs all tests. Everything works correctly unless I run e2e or test-all along with the coverage plugin. I get: java.lang.NoClassDefFoundError: scoverage / Invoker $

Using show this: dependencyClasspath and show e2e: dependencyClasspath , I can see that there is no plugin pool with extension in e2e class . Any idea what is wrong and how to solve it?
