Test-Dependencies in Multiprojects

[atais]

Hello,

I have a cross-compiled project common which contains classes in src/test/scala that I want to share with other modules (in tests).

Following SO: https://stackoverflow.com/questions/8193904/sbt-test-dependencies-in-multiprojects-make-the-test-code-available-to-dependen

I wanted to make it as such:

lazy val common = (project in file("common"))
  .settings(...)
  .cross

lazy val common_2_11 = common("2.11.8")
lazy val common_2_10 = common("2.10.6")

lazy val project1= (project in file("project1"))
  .settings(...)
  .dependsOn(common_2_11 % "compile->compile;test->test")

But later I have also

lazy val main = (project in file("."))
  .aggregate(project1, project2, project3)
  .settings(
    ...
  )

And I get a following error:

[info] Loading project definition from 
/home/project
/home/project/build.sbt:194: error: type mismatch;
 found   : com.lucidchart.sbtcross.BaseProject
 required: sbt.ProjectReference
  .aggregate(project1, project2, project3)
                ^
sbt.compiler.EvalException: Type error in expression

How can I solve this?

I ran into this issue and was able to fix using following code:

.dependsOn(new sbt.Project.Constructor(common_2_11).%("compile->compile;test->test"))

this killed me, spent 3 hours on this today!
