Problems with per-configuration classpath dependencies

[oschrenk]

I have troubles with per-configuration classpath dependencies. I want not only the compile phase to rely on the other project, but also on the test phase.

As soon as I specify the configuration, for example replace dependsOn(commonSpark) with
dependsOn(commonSpark % "compile->compile") compilaton will fail with
the following error:

~/multiproject/build.sbt:90: error: type mismatch;
 found   : com.lucidchart.sbtcross.BaseProject
 required: sbt.ProjectReference
  aggregate(commonConfig_2_11, commonConfig_2_12, commonSpark, consumer, console, dashboard)
                                                               ^
sbt.compiler.EvalException: Type error in expression
[error] sbt.compiler.EvalException: Type error in expression

My end goal is to have not only the compilation but also the test phase depend on the other project,
eg. dependsOn(commonSpark % "compile->compile;test->test") which is what I want)

build.sbt snippet that fails:

...
lazy val root = (project in file(".")).
  settings(settings: _*).
  aggregate(commonConfig_2_11, commonConfig_2_12, commonSpark, consumer, dashboard)

lazy val commonConfig = (project in file("config")).cross

lazy val commonConfig_2_11 = commonConfig("2.11.8").
  settings(libraryDependencies ++= (config ++ specs2))

lazy val commonConfig_2_12 = commonConfig("2.12.2").
  settings(libraryDependencies ++= (config ++ specs2))

lazy val commonSpark = (project in file("common-spark")).
  dependsOn(commonConfig_2_11).
  settings(settings: _*).
  settings(libraryDependencies ++= (config ++ logging ++ spark ++ specs2))

lazy val consumer = project.
  dependsOn(commonSpark % "compile->compile").
  settings(settings: _*).
  settings(mainClass in assembly := Some("consumer.consumerRunner")).
  settings(assemblyOption in assembly := (assemblyOption in assembly).value.copy(includeScala = false)).
  settings(sparkAssembly).
  settings(libraryDependencies ++= (config ++ logging ++ kafka ++ specs2))
...

Is there another way to depend also on the test configuration of another project?

PS
Using sbt-cross 3.0, sbt 0.13.15

[oschrenk]

I found a way by referring to the underlying project

-  aggregate(commonConfig_2_11, commonConfig_2_12, commonSpark, consumer, console)
+  aggregate(commonConfig_2_11, commonConfig_2_12, commonSpark, consumer.project, console)

and

-  dependsOn(commonSpark % "compile->compile;test->test").
+  dependsOn(commonSpark % "compile->compile;test->test").project.

I ran into something similar to this (or perhaps the same issue) where adding sbt-cross seems to hijack the default Project type that is returned by calling project(...) in an SBT file, even if not using .cross on that particular project or one of its dependencies.

The error I got was

error: value settings is not a member of com.lucidchart.sbtcross.BaseProject
possible cause: maybe a semicolon is missing before `value settings'?
  .settings(commonSettings:_*)

And I fixed it by chaining a .project call onto my initial definition like @oschrenk mentioned.
