Cannot run spray examples

Question

I am starting a project with spray, and try to follow their wiki in order to run their example application (to start my project on them). However, I cannot have them working, it seems that the sbt configuration of spray has changed quite a lot since this documentation was written.

The instructions do not work for me when I sbt "project spray-example-simple" shell I got rejected like this:

~/.../spray/project # sbt "project spray-can-examples" shell

[info] Set current project to default-951202 (in build file:/home/jolivier/projects/external/spray/project/)
[error] Not a valid project ID: spray-can-examples
[error] project spray-can-examples
[error]                           ^

Although Build.scala (in the same folder), contains a project with this name:

  lazy val examples = Project("examples", file("examples"))
    .aggregate(sprayCanExamples, sprayClientExamples, sprayIoExamples, sprayServerExamples)
    .settings(exampleSettings: _*)

  lazy val sprayCanExamples = Project("spray-can-examples", file("examples/spray-can"))
    .aggregate(simpleHttpClient, simpleHttpServer)
    .settings(exampleSettings: _*)

So I'm quite disturbed on why I am rejected by sbt. I tried running the sbt project command on several other folders like examples but got the same error. What am I missing? I'm quite disturbed by the the Set current project to default-951202, this does not look good to me but I don't know how to fix that.

Thanks in advance.

Answer 1

You are supposed to run sbt from the cloned repo. root:

spray> sbt11 "project spray-can-examples" shell

spray is the folder where I cloned the repo. Here sbt11 invokes sbt-launch-0.11.2.jar.

It worked just fine.
