spray-testkit, Scala 2.10, and shapeless 2.0.0

[Amir Mohammad Saied]

Hi,

Per spray 1.3.1 announcement email there are now two alternative builds of the `spray-routing` module.

I'm using `spray-routing-shapeless2` (because I depend on parboiled2), but it seems that `spray-testkit` is still pulling `spray-routing`, ergo there are conflicting cross-version suffixes. Is there a build of `spray-testkit` that depends on `spray-routing-shapeless2` instead of `spray-routing`? Actually, will there ever be another spray release? 

Cheers,

Amir

Hi Amir,

your observation is basically correct.

I cannot remember exactly but I think we figured that spray-testkit
should actually be binary compatible with both of spray-routing and
spray-routing-shapeless2. Since spray-testkit defines spray-routing
only as a provided dependency as far as we know everything should work
if you combine it with either of the routing dependencies.

In which way are you currently experiencing the conflict?

Hi Johannes,

Thanks for the prompt reply. I stripped down my `build.sbt` to this:

scalaVersion := "2.10.4"

resolvers ++= Seq(

  "spray repo" at "http://repo.spray.io"

)

libraryDependencies ++= {

  val sprayV    = "1.3.2"

  Seq(

    "io.spray"        %% "spray-routing-shapeless2" % sprayV,

    "org.parboiled" %% "parboiled"                        % "2.0.1",

    "io.spray"        %% "spray-testkit"                   % sprayV % "test"

  )

}

And I'm getting:

[info] Set current project to foo (in build file:/tmp/foo/)

[error] Modules were resolved with conflicting cross-version suffixes in {file:/tmp/foo/}foo:

Hi Amir,

this is a known issue (I forgot about). The cause is that
spray-testkit has a dependency on specs2 which should be marked
"provided" but isn't. See the comment in
https://github.com/spray/spray/issues/947 about how to work around it
for now.

Btw: The workaround is declaring the spray-testkit dependency as:

"io.spray" %% "spray-testkit" % "1.3.2" % "test" exclude("org.specs2",
"specs2_2.10")

Hi Johannes,

Thanks! The workaround worked.
