I'm trying to setup a play2.5 app with slick but i'm getting an error on app startup, any clue how to fix it?
I have created the project from Play Scala Seed activator and I'm trying to add slick to the project, but for now unsuccessfully
The error :

I am wrestling with importing required jar files and deploying them into scala projects after writing build.sbt script. Resolvers deny downloading any scala libraries from neither sonar and maveen 2 resolvers. My scala version is 2.13.0 and sbt is 1.6.1
after compiling sbt builds the program yields errors stated below.
download error: Caught java.io.IOException (Server returned HTTP

Here is my build.sbt script which means error does'nt stem from syntax error.

Look's like you've got an extra whitespace in your version number:
https://repo1.maven.org/maven2/org/scala-lang/scala-library/2.13.0/scala-library-2.13.0 .pom
Fix the Scala version in your build.sbt and it should be it.
I want to use spring-data-neo4j with play framework 2.6 in Scala. But when I add the library dependency I have a compilation error:
object neo4j is not a member of package org
for
import org.neo4j.ogm.annotation.{GraphId, NodeEntity}
I think I don't have good resolvers:
name := """Project-name"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayScala)
resolvers += Resolver.sonatypeRepo("snapshots")
scalaVersion := "2.12.2"
libraryDependencies ++= Seq(
guice,
"org.scalatestplus.play" %% "scalatestplus-play" % "3.0.0" % Test,
"com.h2database" % "h2" % "1.4.194",
"org.springframework.data" % "spring-data-neo4j" % "4.2.6.RELEASE"
)
The classes you are trying to import import org.neo4j.ogm.annotation.{GraphId, NodeEntity} is part of neo4j-ogm-core artifact. so you must include it as shown below to able to access those classes.
libraryDependencies += "org.neo4j" % "neo4j-ogm-core" % "3.0.0-RC1"
I am trying to create a Play application with a back end and a front end(using Scala.js). I separated the code into client and server folders.
For creating a Multi Project Build I looked at this http://www.scala-sbt.org/release/docs/Multi-Project.html and make my build.sbt like this:
name := """ScalaWeb"""
version := "1.0-SNAPSHOT"
lazy val commonSettings = Seq(
scalaVersion := "2.11.7",
libraryDependencies ++= Seq(
jdbc,
cache,
ws,
specs2 % Test
),
libraryDependencies ++= Seq(
"org.sorm-framework" % "sorm" % "0.3.19",
"org.scala-lang" % "scala-compiler" % scalaVersion.value force(),
"com.h2database" % "h2" % "1.3.148"
),
libraryDependencies += "com.typesafe.scala-logging" %% "scala-logging" % "3.1.0",
/*libraryDependencies += "com.typesafe.scala-logging" %% "scala-logging" % "3.1.0",
libraryDependencies += "org.slf4j" % "slf4j-api" % "1.7.12"
libraryDependencies += "ch.qos.logback" % "logback-classic" % "1.1.3"*/
resolvers += "scalaz-bintray" at "http://dl.bintray.com/scalaz/releases",
// Play provides two styles of routers, one expects its actions to be injected, the
// other, legacy style, accesses its actions statically.
routesGenerator := InjectedRoutesGenerator,
scalacOptions += "-Ylog-classpath",
// use this if you just want jawn's parser, and will implement your own facade
libraryDependencies += "org.spire-math" %% "jawn-parser" % "0.8.3",
// use this if you want jawn's parser and also jawn's ast
libraryDependencies += "org.spire-math" %% "jawn-ast" % "0.8.3",
//for reading Json libraries
libraryDependencies += "org.scalaj" %% "scalaj-http" % "2.2.1"
)
lazy val server = (project in file("server")).settings(
commonSettings: _*
).enablePlugins(PlayScala)
lazy val client = (project in file("client")).settings(
commonSettings: _*
).enablePlugins(PlayScala)
fork in run := true
So basically I placed all dependencies into commonSettings and the imported that into the client and server projects.
However, I am getting this error:
[error] (scalaweb/compile:backgroundRun) No main class detected.
Why is this occuring?
Have I set up my build.sbt incorrectly?
That's because your root project (scalaweb) doesn't have a main class.
You can either:
run server's run command by doing: server/run
aggregate client and server under root project
(http://www.scala-sbt.org/0.13/docs/Multi-Project.html#Aggregation)
This might do what you wish.
Runtime classpath according to 'show runtime:fullClasspath' contains only target/scala-2.11/classes and ~/.ivy2/cache/org.scala-lang/scala-library/jars/scala-library-2.11.7.jar.
compile:fullClasspath contains all libraryDependencies jar locations under ~/.ivy2/cache. Why is this? I am getting java.lang.NoClassDefFoundError on sbt run.
build.sbt:
name := "my-server"

scalaVersion := "2.11.7"
libraryDependencies ++= List(

sbt run results:

sbt version 0.13.8
Removing "provided" was the fix here - I was using it incorrectly to resolve ambiguous subversions of dependencies (credit to pfn from freenode #scala)
My build.sbt file (sbt version is 0.13.8):
lazy val commonSettings = Seq(
version := "1.0.0",
scalaVersion := "2.11.6"
)
resolvers += "Typesafe Repo" at "http://repo.typesafe.com/typesafe/releases/"
lazy val root = (project in file(".")).
settings(commonSettings: _*).

)
)

I get this error when trying to compile my project:
[trace] Stack trace suppressed: run last *:update for the full output.
[error] (*:update) sbt.ResolveException: unresolved dependency: com.typesafe.play#play-json_2.11;2.3.4: not found
[error] Total time: 0 s, completed Apr 17, 2015 5:59:28 PM
How can I get this play-json library for my scala 2.11.6?
You need to tell sbt which scala version should use.
You can either be explicit:
"com.typesafe.play" % "play-json_2.11" % "2.3.4",
Or use %% (sbt doc) as follows to tell sbt to use scalaVersion :
"com.typesafe.play" %% "play-json" % "2.3.4",
You can see all of com.typesafe.play's play-json versions here. They don't have a 2.3.4 version; try using 2.4.0-M3 instead.
"com.typesafe.play" %% "play-json" % "2.4.0-M3"
Mind the double %% so scalaVersion is used properly to resolve the dependency.
