I m doing simple Http GET request by using dispatch library in SBT.
My Code:
def getReq(){
val svc = url(GlobalObjects.BASE_GET_REQUEST_URL);
val response : Future[String] = Http(svc OK as.String)
response onComplete {
case Success(content) => {
println("Successful response" + content)
}
case Failure(t) => {
println("An error has occurred: " + t.getMessage)
}
}
}
}
When I run from SBT console it shows the following unKnown Error. Someone has any idea what is wrong here?

Seems to be the same issue as with your other question.
net.databinder.dispatch is using 2.11 instead 2.10.

I have created a simple project in Graphx, as soon as I am trying to run this test project, I am getting AbstractMethodError, error is comming inside this method edgeListFile, looks like something related to logger which I am not abe to see, Please help.
Here is my .scala file
object graphtest extends App {

val spark = SparkSession.builder.master("local").appName("learning spark").getOrCreate
val sc = spark.sparkContext
val graph1 = GraphLoader.edgeListFile(spark.sparkContext, "E:\\code\\Cit-HepTh.txt")
val res: (VertexId, Int) = graph1.inDegrees.reduce((a, b) => if (a._2 > b._2) a else b)
graph1.edges.collect().take(10).foreach(println)
}
Here is my build.sbt file

I'm tring to setup a project with play framework and postgres with slick-codegen. My project is compiling without errors And the Tables class generated is correct. But when I run the project it give me the play.api.UnexpectedException: Unexpected exception[NoClassDefFoundError: slick/backend/DatabaseConfig].

I have my project split in 2 subprojects. The Play project and the codegen project that is used to generate the Tables class.
My build.sbt looks like this:
import sbt.Keys._
val slickVersion = "3.2.0"
scalaVersion := "2.11.8"
// The Play project itself
lazy val root = (project in file("."))
.settings(
libraryDependencies ++= List(

"net.codingwell" %% "scala-guice" % "4.1.0",

"com.typesafe.play" %% "play-slick-evolutions" % "2.0.2"
)
)
.settings(sharedSettings)
.enablePlugins(Common, PlayScala)
.settings(
name := """Play app"""
)
.dependsOn(codegen)
lazy val codegen = project
.settings(sharedSettings)
.settings(
libraryDependencies ++= List(
"com.typesafe.slick" %% "slick-codegen" % slickVersion
)
)
lazy val sharedSettings = Seq(
scalaVersion := "2.11.8",
scalacOptions := Seq("-feature", "-unchecked", "-deprecation"),
libraryDependencies ++= List(

"org.slf4j" % "log4j-over-slf4j" % "1.7.23", // for any java classes looking for this
"ch.qos.logback" % "logback-classic" % "1.2.1",

"joda-time" % "joda-time" % "2.9.7",
"org.joda" % "joda-convert" % "1.8"
)
)
I also tried removing all the code that use database and the Tables class but i still get this error.
I use a custom postgres driver and it is in the codegen project but is i add the dependsOn(codegen) in the root project, it should not be a problem. Also it is compling without problems with sbt compile.
EDIT:
After some testings, i changed the slick version to 3.1.1 and com.github.tminglei versions to 0.14.3 and it now works for me.
I had the same classapth problem and in the end used the following versions in a play-2.5.x and scala-2.11 project:
libraryDependencies ++= List(
"com.typesafe.play" %% "play-slick" % "2.1.0",
"com.typesafe.play" %% "play-slick-evolutions" % "2.1.0",
"com.typesafe.slick" %% "slick" % "3.2.0",
"com.github.tototoshi" %% "slick-joda-mapper" % "2.3.0"
}
The slick.backend.DatabaseConfig comes from slick-3.1.0 that was needed by play-slick-2.0.2. Since you wanted slick-3.2.0 you need to use play-slick-2.1.0 see https://github.com/playframework/play-slick and https://github.com/tototoshi/slick-joda-mapper .
Getting started with sbt.
I am getting this error during sbt assembly

any idea why am getting that and how can I solve it ?

I did managed to solve it by adding

case x => MergeStrategy.first
}
assemblyMergeStrategy in assembly := {
case PathList("META-INF", xs # _*) => MergeStrategy.discard
case x => MergeStrategy.first
}
The ScalaTest and Scalactic version numbers need to match. You have a ScalaTest 2.2.6 trying to use a Scalactic 3.0.0, so that's the problem. One of your dependencies is perhaps using Scalactic 3.0.0.

What options do I have to fix it?
Thanks
The issue as it seems transitive dependency of the dependency is resulting with two different versions of metrics-core. The best thing to do would be to used the right library dependency so that you end up with a single version of this library. Please use https://github.com/jrudolph/sbt-dependency-graph , if it is difficult to figure out dependencies.
If it is not possible to get to a single version then you would most likely to go down exclude route . I assume, this only work, if there is compatibility between the all required versions.
