NoClassDefFoundError running tests in SBT with scoverage plugin - scala

Question

I have an SBT project with structure like here: https://orrsella.com/2014/09/24/integration-and-end-to-end-test-configurations-in-sbt-for-scala-java-projects/. It includes standard main and test directories and additionally it and e2e. There is also a task "test-all" which runs all tests. Everything works correctly unless I run e2e or test-all together with coverage plugin. I'm getting: java.lang.NoClassDefFoundError: scoverage/Invoker$
Using show it:dependencyClasspath and show e2e:dependencyClasspath, I can see that e2e classpath is missing scoverage plugin jars. Any idea what's wrong and how to solve it?

Answer 1

It seems that you need to add a setting to your sbt project:
works for me, with "org.scoverage" % "sbt-scoverage" % "1.5.0"
coverageEnabled in Test := true
and I have found that for version <1.4.0 there was another solution:
coverageEnabled.in(ThisBuild ,Test, test) := true
