"object github is not a member of package com" for WeKanban2 example project in Scala in action book - scala

Question

I'm new in Scala so started from reading "Scala in Action" book 2013 year. But I cannot build plain sbt WeKanban2 project. I use newer version scala and sbt then in example.
I get error when run sbt:
error: object github is not a member of package com import com.github.siasia.WebPlugin._
my build.properties:
//was sbt.version=0.12.0
sbt.version=0.13.7
plugins.sbt
// was libraryDependencies <+= sbtVersion(v => "com.github.siasia" %% "xsbt-eb-plugin" (v+"-0.2.11.1"))
addSbtPlugin("com.earldouglas" % "xsbt-web-plugin" % "0.7.0")
build.sbt

println("Database started ! ")
case Some(_) =>
println("H2 Database already started")
}
}

val stopH2Task = stopH2 in H2 :={

case Some(_) =>
println("Stopping database...")
process.foreach{_.destroy()}
process = None
println("Database stopped...")
}
}
}
object MainBuild extends Build {
import H2TaskManager._
lazy val scalazVersion = "6.0.3"
lazy val jettyVersion = "7.3.0.v20110203"
lazy val wekanban = Project(
"wekanban",
file(".")) settings(startH2Task, stopH2Task)}
What should I do to fix this error? What should I do to start app from Idea 14 in debug mode?

Answer 1

Your import
import com.github.siasia.WebPlugin._
failed to find path github and below. In your plugins.sbt you wrote:
// was libraryDependencies <+= sbtVersion(v => "com.github.siasia" %% "xsbt-eb-plugin" (v+"-0.2.11.1"))
addSbtPlugin("com.earldouglas" % "xsbt-web-plugin" % "0.7.0")
The github-path probably existed in the outcommented com.github.siasia.xsbt-eb-plugin. However the com.earldouglas.xsbt-web-plugin have only the path com.earldouglas.xwp. You should check out if any of the classes there (https://github.com/earldouglas/xsbt-web-plugin/tree/master/src/main/scala) resembles what you need to import.

Probably not related exactly to this package but similar. The library was present in sbt and everything looked ok. But I still was unable to build the project so I went to my $HOME/.ivy2/cache located the dependency directory and deleted it, then went back the $PROJECT_HOME/ and executed sbt build
