Why does SBT compile just the last subproject? - scala

I'm getting crazy, really :-(
Given the following SBT build file...
import sbt._
import sbt.Keys._
object BrixBuild extends Build {
lazy val buildSettings = Project.defaultSettings ++ Seq(
organization := "com.mycompany",
version := "0.1-SNAPSHOT",
scalaVersion := "2.10.0-RC3",
scalacOptions in Compile ++= Seq("-encoding", "UTF-8", "-deprecation", "-feature", "-unchecked"),
resolvers += Resolvers.typesafe,
target := file("target")
)
lazy val util = Project(
id = "brix-util",
base = file("brix-util"),
settings = buildSettings ++ Seq(
libraryDependencies ++= Dependencies.util
)
)
lazy val slick = Project(
id = "brix-slick",
base = file("brix-slick"),
settings = buildSettings ++ Seq(
libraryDependencies ++= Dependencies.slick
)
)
}
object Resolvers {
val typesafe = "Typesafe Releases" at "http://repo.typesafe.com/typesafe/releases"
}
object Dependencies {
private object Compile {
val commonsCodec = "commons-codec" % "commons-codec" % "1.7"
val slick = "com.typesafe" %% "slick" % "1.0.0-RC1"
}
private object Test {
val specs2 = "org.specs2" %% "specs2" % "1.12.3" % "test"
val slf4j = "org.slf4j" % "slf4j-nop" % "1.6.4" % "test"
val h2 = "com.h2database" % "h2" % "1.3.166" % "test"
}
val util = Seq(Compile.commonsCodec, Test.specs2, Test.slf4j)
val slick = Seq(Compile.slick, Test.specs2, Test.slf4j, Test.h2)
}
... only the last subproject get compiled. Why? Am I missing something?
Any help would be really appreciated. Tx.

You should define a "parent" project that aggregates the subprojects. For an example see https://github.com/typesafehub/scalalogging/blob/master/project/Build.scala.

Scala Flink get java.lang.NoClassDefFoundError: scala/Product$class after using case class for customized DeserializationSchema

It work fine when using generic class.
But get java.lang.NoClassDefFoundError: scala/Product$class error after change class to case class.

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.

What should I do to fix this error? What should I do to start app from Idea 14 in debug mode?
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

Confused how to set up a multi-project sbt project

I'm using sbt .13 here.
I have this so far:
import sbt._
import Keys._
import play.Project._
object ApplicationBuild extends Build {
val appVersion = "1.0"
resolvers += "local maven" at "/Users/blankman/.m2/repository/"
val commonDependencies = Seq()

)
val serviceDependencies = Seq(

)
val webDependencies = Seq(

"mysql" % "mysql-connector-java" % "5.1.30",
"com.typesafe.slick" %% "slick" % "2.0.1"
)
lazy val common = Project(
id = "app-common",
base = file("app-common"),
dependencies = commonDependencies
)
lazy val models = Project(
id = "app-models",
base = file("app-models"),
settings(modelDependencies: _*)
)
).dependsOn(common)
lazy val services = Project(
id = "app-services",
base = file("app-services"),
settings = Seq(
libraryDependencies ++= serviceDependencies
)
).dependsOn(models, common)
lazy val web = play.Project("app-web", appVersion, webDependencies,
path = file("app-web"))
.settings(playScalaSettings: _*)
.dependsOn(services)
}
This doesn't work. For example, if I go into:
project app-models
and try and compile, it says compile isn't valid or something.
I'm really confused how to set up a project. What is the correct way?
Looking at this slide #10 here http://jsuereth.com/scala/2013/06/11/effective-sbt.html it says I can do:
lazy val web = (
Project("app-models", file("app-models"))
settings(
libraryDependencies += modelDependencies
)
)
But when I do this I get an error also.
I basically have a few projects inside of sbt:
common
models
services
web (which is play)
models depends on commons
services depends on commons + models
web depends on services
Can someone help me get this to work?
There are a few issues I found in your build definition, but since you bought up Josh's Effective sbt talk, I think we should go whole hog on the style.

notes
settings parameter vs settings method
For models and services, you're passing in settings sequence into Project(...) constructor, so the default settings are likely not loaded. You can pass in the default settings manually, or use settings(...) method on Project, which I would recommend.
lazy val appModels = (project in file("app-models")).
settings(
libraryDependencies ++= modelDependencies
).
dependsOn(appCommon)
Josh uses postfix notation using parenthesis, but I prefer using dot notation for this, so that's a slight deviation from the talk.
libraryDependencies ++=
As the above example, you have to pass modelDependencies to libraryDependencies. You had it calling directly into settings.
resolvers
The resolvers setting is not passed into anything, which likely is not correct.

How can I add jars from more than one unmanaged directory in an SBT .scala project configuration

I'm trying to get SBT to build a project that could have more than one unmanaged directory. If I had a single directory, I could easily do it like this:
unmanagedBase := file( "custom-libs" ).getAbsoluteFile
But since I have two directories with unmanaged jars, I need to be able to add them all. I have found some information in here, but still doesn't seem useful for my full .scala file build.
I have created a simple project that shows the issue in here. And below is my Build.scala file.
UPDATE
I've got some help form the sbt-users list and have been able to define the unmanaged-jars correctly, but the code still doesn't compile (but sbt show unmanaged-jars shows the files correctly).
import sbt._
import com.github.siasia._
import PluginKeys._
import Keys._
object Build extends sbt.Build {
import Dependencies._
val unmanagedListing = unmanagedJars := {
Dependencies.listUnmanaged( file(".").getAbsoluteFile )
}
lazy val myProject = Project("spray-template", file("."))
.settings(WebPlugin.webSettings: _*)
.settings(port in config("container") := 8080)
.settings(
organization := "com.example",
version := "0.9.0-RC1",
scalaVersion := "2.9.1",
scalacOptions := Seq("-deprecation", "-encoding", "utf8"),
resolvers ++= Dependencies.resolutionRepos,
libraryDependencies ++= Seq(
Compile.akkaActor,
Compile.sprayServer,
Test.specs2,
Container.jettyWebApp,
Container.akkaSlf4j,
Container.slf4j,
Container.logback
),
unmanagedListing
)
}
object Dependencies {
val resolutionRepos = Seq(
ScalaToolsSnapshots,
"Typesafe repo" at "http://repo.typesafe.com/typesafe/releases/",
"spray repo" at "http://repo.spray.cc/"
)
def listUnmanaged( base : RichFile ) : Keys.Classpath = {
val baseDirectories = (base / "custom-libs") +++ ( base / "custom-libs2" )
(baseDirectories ** "*.jar").classpath
}
object V {
val akka = "1.3"
val spray = "0.9.0-RC1"
val specs2 = "1.7.1"
val jetty = "8.1.0.v20120127"
val slf4j = "1.6.4"
val logback = "1.0.0"
}
object Compile {
val akkaActor = "se.scalablesolutions.akka" % "akka-actor" % V.akka % "compile"
val sprayServer = "cc.spray" % "spray-server" % V.spray % "compile"
}
object Test {
val specs2 = "org.specs2" %% "specs2" % V.specs2 % "test"
}
object Container {
val jettyWebApp = "org.eclipse.jetty" % "jetty-webapp" % V.jetty % "container"
val akkaSlf4j = "se.scalablesolutions.akka" % "akka-slf4j" % V.akka
val slf4j = "org.slf4j" % "slf4j-api" % V.slf4j
val logback = "ch.qos.logback" % "logback-classic" % V.logback
}
}
I just post the fragment from my build.sbt file, using sbt 0.11.x. It could probably be refactored a bit.
unmanagedJars in Compile <++= baseDirectory map { base =>
val libs = base / "lib"
val dirs = (libs / "batik") +++ (libs / "libtw") +++ (libs / "kiama")
(dirs ** "*.jar").classpath
}
You can add additional paths to the list of folders to scan for unmanaged dependencies. For example, to look in a folder called "config" in addition to "lib" for the run task, you can add the following. For the compile task change Runtime to Compile.
unmanagedClasspath in Runtime <+= (baseDirectory) map {
bd => Attributed.blank(bd / "config")
}
As answered by Eugene Vigdorchik, what made it work as the following code:

Here's a general solution to recursive loading of unmanaged JARs (for sbt 0.13.x): https://stackoverflow.com/a/29357699/1348306

sbt web plugin: Not a valid key: jetty-run (similar: jetty-port, jetty-context, run)

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
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.
