Today is my first day with Finch.
I am unable to find the right set of SBT dependencies for finch and finagle.
I have tried all the dependencies as shown in Image 2
You are using Scala 2.12 but your dependencies are for Scala 2.11.
This is the correct way to write what you need:
libraryDependencies += "com.github.finagle" %% "finch-core" % "0.13.0"
Build.scala, % and %% symbols meaning
I want to use AkkaSpec in (Akka 2.3.14)
I'm trying to make TCP-file-IO using actor, sbt, intellij.
I wrote the dependency in build.sbt like below code
libraryDependencies ++= Seq(
"com.typesafe.akka" %% "akka-testkit" % "2.3.14",
)
They can import "akka.testkit" but when I "import akka.testkit.AkkaSpec" in my scala file, it can't.
How to use AkkaSpec in akka??? Please help me. Thx.
AkkaSpec is not part of the released artifacts (see here), but you could copy the source.
I would like to use AnormCypher in my Scala project (with SBT).
I am not using Play! Framework. Can I use AnormCypher anyway?
If yes, how can I install the library. There is no .jar file or something.
As the official github page said, I added
resolvers ++= Seq(
"anormcypher" at "http://repo.anormcypher.org/",
"Typesafe Releases" at "http://repo.typesafe.com/typesafe/releases/"
)
libraryDependencies ++= Seq(
"org.anormcypher" %% "anormcypher" % "0.6.0"
)
to my build.sbt.
But Intellij produces Unresolved Dependencies errors.
I am new to scala and neo4j and I am seriously lost. If someone can help and tell me what to do.
Thank you.
I want to use some of the Play2 libraries (for example, Json API and WS API) in separate scala project. Is there any way to add libs to a libraryDependency list at built.scala. Or may be I need to do something else.
Thanks a lot!
To depend on play-core we need to add in build.sbt:
scalaVersion :="2.10.0"
libraryDependencies ++= Seq("play" % "play_2.10" % "2.1.0")
resolvers ++= Seq("Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/")
this for scala and play version 2.1.

I want to develop a rather simple web application in Scala, with Lift or Play framework, using Eclipse as an environment and some simple webserver like Jetty. However, to my inexpressibly great surprise, I cannot setup the whole thing to work together. I also could not find any sensible simple and clear guide on how to do this. After a half day of searching, I came to an opinion that everyone around seem to use a mix of sbt/maven and feel it ok migrating from one to another and writing project config files manually just to get a simple blank project to begin with.
There is no plain simple way to create even an empty project. With Java I remember that it was a couple of clicks - to integrate a webserver into Eclipse, create a simple web app project and run it right from there. Where had gone the power and simplicity of Scala in this case? And that's only if I want to try Lift. What if I would like to try Play also, should I travel the same path again?
Is there anywhere a simple and complete guide that describes how to setup the environment so that it is possible to start developing the apps right away?
UPDATE: I have reached a successful Play project integration with Eclipse, with all the capabilities that Play has out-of-the-box, thanks to the advice of Peter Gwiazda. I am using this setup for developing right now. However, my question of interest remains: what are other ways to acheive similar functionality with other frameworks such as Lift, Scalatra and others?
With Playframework 2.0 it's pretty simple. Just follow the tutorial
http://www.playframework.org/documentation/2.0/ScalaTodoList
With Play you don't need anything else - Play already contains a server.
IMHO Play is way easier to work with than Lift.
EDIT
OK, you asked for it ;-)
Here's a bleeding edge setup for Scalatra with SBT Coffeescript & LESS (see HERE for SBT-Eclipse dependency management)
1) eclipsify a test project
2) in project root create "build.sbt" file:
import AssemblyKeys._
import Keys._
name := "your project name"
version := "1.0"
scalaVersion := "2.9.1"
fork in run := true
resolvers ++= Seq(
"Sonatype OSS Snapshots" at "http://oss.sonatype.org/content/repositories/snapshots/",
"Typesafe repository" at "http://typesafe.artifactoryonline.com/typesafe/ivy-releases/"
)
seq(webSettings :_*)
seq(assemblySettings: _*)
seq(coffeeSettings: _*)
seq(lessSettings:_*)
(LessKeys.mini in (Compile, LessKeys.less)) := false
libraryDependencies ++= Seq(
"org.scalatra" %% "scalatra" % "2.1.0-SNAPSHOT",
"org.scalatra" %% "scalatra-scalate" % "2.1.0-SNAPSHOT",
"org.scalatra" %% "scalatra-lift-json" % "2.1.0-SNAPSHOT",
"org.scalatra" %% "scalatra-anti-xml" % "2.1.0-SNAPSHOT",
"org.scalatra" %% "scalatra-fileupload" % "2.1.0-SNAPSHOT",
"org.eclipse.jetty" % "jetty-webapp" % "8.1.0.RC2" % "test;container;provided",
"javax.servlet" % "javax.servlet-api" % "3.0.1" % "provided"
)
unmanagedBase <<= baseDirectory { base => base / "/src/main/webapp/WEB-INF/lib/" }
3) create folder "project" in root with plugins.sbt file:
libraryDependencies <+= sbtVersion(v => "com.github.siasia" %% "xsbt-web-plugin" % (v+"-0.2.10"))
resolvers += Resolver.url("sbt-plugin-releases", new URL("http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases/"))(Resolver.ivyStylePatterns)
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.0.0-M3")
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.7.2")
addSbtPlugin("me.lessis" % "coffeescripted-sbt" % "0.2.2")
addSbtPlugin("me.lessis" % "less-sbt" % "0.1.9")
4) from terminal/command prompt start sbt & enable code reloading:
# sbt
> ~;container:start;container:reload /
Open up the Scalatra Book and start hacking ;-)
ORIGINAL
Have to mention it, but a micro framework a la Scalatra, Spray, or Unfiltered might be of interest as well.
That is, if you're not looking for the kitchen sink that Lift and Play provide; if you are looking for the kitchen sink and want to get rolling quickly, Play 2.0 does indeed look quite nice.
Disclaimer: I'm a member of the Vaadin team.
You could also try out Vaadin which works perfectly with Scala, HOWTO here. You can also use Maven or SBT if you want. You should also check out Scaladin, the semi-official Scala wrapper for Vaadin.
Vaadin is a component based library (just one JAR with no dependencies) and it allows you to create your Ajax and HTML5 enabled UI in pure Scala without any HTML templates, RPC, XML or JavaScript.
You could use my Maven prototype for Scalatra, then simply import the maven project into Eclipse. Quite nice and you're not forced to use SBT.

You can have a look on my Github repo where I have a project that uses Lift and Jetty (as an embedded server). It's not well documented yet but is small enough to grasp how it's working
P4G Server Repo
The server starts from com.p4g.Server object (which is called within com.p4g.Main Application object )
My Lift boostrap object is located in boostrap.liftweb package
BTW, I'm also using ScalaQuery and ScalaZ
