Question

I'm trying to set up a scala sbt project with the lift web framework. I'm using

  • scala 2.9.0-1
  • sbt 0.10.1
  • lift 2.3
  • xsbt-web-plugin 0.1.1 (which is only on scala 2.8.1, see end of question)

(quite recent versions I know). I followed http://d.hatena.ne.jp/k4200/20110711/1310354698 and https://github.com/siasia/xsbt-web-plugin/blob/master/README.md to obtain the following sbt configuration files:

project/build.properties

sbt.version=0.10.1

project/plugins/build.sbt

resolvers += "Web plugin repo" at "http://siasia.github.com/maven2"

libraryDependencies <+= sbtVersion(v => "com.github.siasia" % "xsbt-web-plugin_2.8.1" % ("0.1.1-"+v))

project/Build.scala

import sbt._

object BuildSettings {
  val buildOrganization = "xbaz"
  val buildScalaVersion = "2.9.0-1"
  val buildVersion      = "0.0.1"

  val buildSettings = Defaults.defaultSettings ++ Seq (
    organization := buildOrganization,
    scalaVersion := buildScalaVersion,
    version      := buildVersion)
}

object Resolvers {
  val webPluginRepo = "Web plugin repo" at "http://siasia.github.com/maven2"
  val jettyRepo = "Jetty Repo" at "http://repo1.maven.org/maven2/org/mortbay/jetty"

object Dependencies {

  val logDeps = Seq(grizzled, log4j_over_slf4j, logback_core, logback_classic)
}


object MyBuild extends Build {
  import com.github.siasia.WebPlugin._ // web plugin
  import BuildSettings._
  import Dependencies._
  import Resolvers._

  //End dependencies

  lazy val root = Project("root", file(".") , settings = buildSettings ++
    Seq( name := "foo")
  ) aggregate(core, cli, web)
    //  mainClass:= Some("Main"))

  lazy val core : Project = Project("core", file("core"), delegates = root :: Nil, settings = buildSettings ++
    Seq(
    name := "foo-core",
    libraryDependencies ++= logDeps ++ Seq(scalaTest, apacheHttpClient, apacheHttpCore)

  lazy val cli: Project = Project("cli", file("cli"), settings = buildSettings ++

    libraryDependencies ++= logDeps ++ Seq(apacheHttpClient),
    fork in run := true,
    javaOptions in run += "-Djava.library.path=/home/jolivier/Projets/asknow/lib/jnotify-lib-0.93"
  )) dependsOn(core) settings(
  )

  lazy val web: Project = Project("web", file("web"), settings = buildSettings ++
    Seq (resolvers := Seq(webPluginRepo, jettyRepo),
    name := "foo-http",
    libraryDependencies ++= logDeps ++ webPluginDeps ++ liftDeps
    ) ++ 
    webSettings
  ) dependsOn(core)
}

When I try sbt jetty-run I get the following error message:

[error] Not a valid command: jetty-run
[error] Not a valid project ID: jetty-run
[error] Not a valid configuration: jetty-run
[error] Not a valid key: jetty-run (similar: jetty-port, jetty-context, run)
[error] jetty-run
[error]

So I noticed that some jetty-* commands do exist, but not the one I want, so I printed webSettings which is supposed to contain all these new settings and it contains jetty-context and jetty-port, as well as jetty-configuration and others, but not jetty-run :s.

What did I go wrong to not have jetty-run?

I tried switching to scala-2.8.1 since the web plugin is currently only on scala 2.8.1, by changing my buildScalaVersion variable but that didn't change anything. Do you have any idea?

Thanks in advance for your help

Was it helpful?

Solution

Tasks are aggregated; commands are not.

jetty-run is a command. It is only available in the context of the sub-project with the web plugin settings.

> project web
> jetty-run

Once it is running, you can use the prepare-webapp task to redeploy the webapp. This can be run from the context of the root project, because it aggregates the web project.
