I am trying to create a REST service using Spray Servlet, but does not compile.
Below you can find my build.sbt:
name := "someservice"
version := "0.0.1"
scalaVersion := "2.10.0"
resolvers += "spray repo" at "http://repo.spray.io"
libraryDependencies += "io.spray" % "spray-servlet" % "1.0-M3"
libraryDependencies ++= Seq(
"io.spray" % "spray-servlet" % "1.0-M3",

"org.eclipse.jetty.orbit" % "javax.servlet" % "3.0.0.v201112011016" artifacts Artifact("javax.servlet", "jar", "jar")
)
There error I get com 'sbt update compile' is:
[error] bad symbolic reference. A signature in package.class refers to term Either

Do I have to add the scala library to the sbt build file as well or am I missing something else?
tld;dr: try replacing 1.0-M3 with 1.1-M7
It looks like the Spray artifacts you're using were compiled against Scala 2.9.2, which is not binary compatible with Scala 2.10. Usually, Scala artifacts contain the Scala binary version in the artifact name, precisely because major Scala versions are not binary compatible.
Later spray-util milestones were compiled against Scala 2.10.0-RC5 (based on the pom), which technically should work.
Solved by using all the same spray versions (1.1-M7) and upgrading to Scala 2.10.1

I am new to the Scala env and trying to build a test project using play with 'scalikejdbc' for SQL integration. Here is my build.sbt following the documents at http://scalikejdbc.org/documentation/playframework-support.html

However while trying to update the application before running i am getting the below issue
[error] (update) found version conflict(s) in library dependencies; some are suspected to be binary incompatible:

following are relevant versions :

version conflict(s) in library dependencies; some are suspected to be binary incompatible
This means that you have at least two dependencies that are needing a 3rd one but they need 2 different versions which are supposed to be incompatible.
As only one can be included and used for your code, SBT is telling you: "I am going to pick one version but there are risks that this version won't work as you might have code that rely on the other version and this might be incompatible".
You have 2 options:
force a version (for scala-parser-combinators) with dependencyOverrides for instance if you know that actually there's no incompatibility, or at least on the way you use the libraries
upgrade or downgrade the libraries (scalikejdbc or play) so that all libraries depend on the same version of the conflicting one (scala-parser-combinators).
In this case, I would downgrade scalikejdbc because there's no newer play version (as of today)
I have installed Flink, Scala and sbt

Few points I want to mention here regarding the SBT dependencies issues are:
Please add scalaVersion := "2.12.11" in build.sbt file like this, which includes the Scala version in your SBT dependencies automatically due to this%%.
name := "flink-streaming-demo"
scalaVersion := "2.12.11"
val flinkVersion = "1.10.0"
libraryDependencies += "org.apache.flink" %% "flink-scala" % flinkVersion % "provided"
libraryDependencies += "org.apache.flink" %% "flink-streaming-scala" % flinkVersion % "provided"
If you want Scala version specific SBT dependencies then use % like this:
libraryDependencies += "org.apache.flink" % "flink-scala_2.12" % flinkVersion % "provided"
libraryDependencies += "org.apache.flink" % "flink-streaming-scala_2.12" % flinkVersion % "provided"
In worst case if all these does not work then simply delete or rename these existing .sbt and .ivy2 hidden folder in your system home directory, where your all dependecies and plugins get sotred after downloading from maven central and then refresh/build the SBT project.
SBT dependency format
libraryDependencies += groupID % artifactID % revision % configuration
Meaning of % and %%
%: A method used to construct an Ivy Module ID from the strings you supply.
%%: When used after the groupID, it automatically adds your project’s Scala version (such as _2.12) to the end of the artifact name.
NOTE: To get more details click here.
summing up the comments since perhaps it is a bit hard to know what you should do
In general, if you get an "Unresolved dependencies" error, look at mvnrepository.com, search for your artifact:
https://mvnrepository.com/artifact/org.apache.flink/flink-scala
This tells you (second column) which Scala versions are supported by it. In this case, the library is available for 2.11.x and 2.12.x.
Thus, you have to use a Scala version compatible with that in your build, in build.sbt:
ThisBuild / scalaVersion := "2.12.10"
I am new to scalatest and scalamock. Here is what I have it in my sbt file
name := "cakepattern"
version := "0.1"
scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
"org.scalatest" %% "scalatest" % "3.0.0" % "test",
"org.scalamock" %% "scalamock-core" % "3.1.1" % "test",
"org.scalamock" %% "scalamock-scalatest-support" % "3.1.1" % "test",
"org.scalacheck" %% "scalacheck" % "1.13.0" % "test"
)
And here is a class that I am trying to mock
package config
import dto.User
import services.AuthServiceComponent
import org.scalatest.mockito.MockitoSugar._
import services.impl.DefaultUserAuthServiceComponent
trait MockAuthServiceComponent extends AuthServiceComponent{
val x = mock[AuthServiceLike]
type AuthService = x.type
override val userAuthService = x
}
When I am do sbt test:compile I get the following error

What am I missing?
[Edit]
So the problem I was having before is resolved but now I get this
Error:scalac: missing or invalid dependency detected while loading class file 'AbstractMockFactory.class'.
Could not access type NoArgTest in trait org.scalatest.Suite,
because it (or its dependencies) are missing. Check your build definition for

A full rebuild may help if 'AbstractMockFactory.class' was compiled against an incompatible version of org.scalatest.Suite.
Any suggestions?
Try adding Mockito to your sbt file:
libraryDependencies ++= Seq(
"org.scalatest" %% "scalatest" % "3.0.0" % Test,
"org.scalamock" %% "scalamock-core" % "3.1.1" % Test,
"org.scalamock" %% "scalamock-scalatest-support" % "3.1.1" % Test,
"org.scalacheck" %% "scalacheck" % "1.13.0" % Test,
"org.mockito" % "mockito-all" % "1.10.19" % Test
)
Take care, it's a simple "%", not a double one (it's a java dependency)
Other versions here : https://mvnrepository.com/artifact/org.mockito/mockito-all if 1.10.19 is not compatible with your codebase
EDIT :
Not sure that will help your second problem, but try that in an SBT console :
> clean
> compile
Versions <3.3.0 are not compatible with Scalatest 3+.
I suggest updating to scalamock 3.4.2 (latest one as of writing).
You can always find the newest version on Maven Central.
Also, no need to specify scalamock-core, that gets pulled in automatically.
scalacheck 3.2 depend on scalatest 2.1.3, but you used scalatest 3.0.0, so they are not compatibal. remove the scalatest dependence will resolve the problem.
I was using sbt to compile a scala code, and got the following error message

I was using the play json library to parse json files in my main class. And the content of the build.sbt file is like the following:
name := "json_parser"
version := "1.0"
scalaVersion := "2.10.1"
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.6.1"
resolvers += "Typesafe Repo" at "http://repo.typesafe.com/typesafe/releases/"
libraryDependencies += "com.typesafe.play" %% "play-json" % "2.4.8"
I am totally new to scala and the play framework. Does anyone has any clue about this problem? Thanks!
I'm trying to add parboiled2 as a dependency to my project, and follow the Calculator example but it conflicts with spray.
My current build.sbt file includes:
"io.spray" %% "spray-json" % "1.3.1" withSources() withJavadoc(),
"io.spray" %% "spray-can" % sprayV withSources() withJavadoc(),
"io.spray" %% "spray-routing" % sprayV withSources() withJavadoc(),
"io.spray" %% "spray-testkit" % sprayV % "test" withSources() withJavadoc(),
When I add
"org.parboiled" %% "parboiled" % "2.0.1" withSources() withJavadoc(),
I get
[error] Modules were resolved with conflicting cross-version suffixes in {file:/blar/blar}blar-blar:
[error] com.chuusai:shapeless _2.10.4, _2.10
[error] org.scalamacros:quasiquotes _2.10, _2.10.3
java.lang.RuntimeException: Conflicting cross-version suffixes in: com.chuusai:shapeless, org.scalamacros:quasiquotes
So did some googling, and as usual people suggest using the exclude directive of SBT (which I don't believe makes logical sense as it will inevitably result in problems like ClassNotFoundException and NoSuchMethodError). I tried it nevertheless:
"org.parboiled" %% "parboiled" % "2.0.1" withSources() withJavadoc()
exclude("com.chuusai", "shapeless_2.10.4") exclude("org.scalamacros", "quasiquotes_2.10")
And surprise surprise when I try to run assembly I get
[error] java.lang.ClassNotFoundException: scala.quasiquotes.QuasiquoteCompat$
I also get a load more errors:
[error] bad symbolic reference

If I comment out the Spray dependencies (and code) I can successfully assembly a jar with the Calculator example.
This is a major show stopper for me using parboiled2. Is there some way other than exclude directives in order to make this stuff work? Does anyone have a working build file with both Spray and parboiled2? If someone has managed to get around dependency hell with onejar or ProGuard I'd love it if they could explain just how.
UPDATE:
My build file:
resolvers ++= Seq(

Scala 2.11
It seems "simply" moving 2.11 may solve this, but this isn't always that easy if one has some other libraries that are not 2.11 ready. Nevertheless I tried it, and the second I added parboiled2 as a dependency it broke my build again, sigh, here is the new problem: Parboiled2 causes "missing or invalid dependency detected while loading class file 'Prepender.class'"
The same answer as for Scala 2.11 should work here as well: replace spray-routing with spray-routing-shapeless2.
I would have to look at the whole build.sbt file to understand what is happening but I can use the dependencies you mention without problem with sbt 0.13.7 and scala 2.11.
What sbt version? What Scala version? 2.10 it seems. Why? Are you stuck with those versions?
For reference, here are the build.sbt, plugins.sbt and build.properties files I used to test this scenario.
