When running play compile, I get a compile-time error.
[error] test.scala:14: object BOMInputStream is not a member of package org.ap
ache.commons.io.input
[error] import org.apache.commons.io.input.BOMInputStream
[error] ^
[error] test.scala:80: not found: type BOMInputStream
[error] val bomIn = new BOMInputStream(fileInpStream, false)
[error] ^
[error] two errors found
However, I successfully ran a scalatest test using the BOMInputStream in the same play project within the /test directory.
When I comment out the offending lines in the above compile-time error, the test succeeds.
Note that I've updated my /project/Build.scala appropriately:
"org.apache.commons" % "commons-io" % "1.3.2"
After deleting a JAR, which contained the BOMInputStream class, from my PLAY-PROJECT/lib/ directory, I was able to compile.

While upgrading from play 2.4 -> 2.5 I hit an issue where
Symbol 'type <none>.iteratee.Iteratee' is missing from the classpath
I checked the migration guide and included the dependency "com.typesafe.play" % "play-iteratees_2.11" % 2.5.18 into sbt. From the new play-iteratees repo, I was under the impression that package play.api.libs.iteratee is where I'd find what to import. But it doesnt seem to work?
Error log:

Learning Scala since yesterday, I've build a project to interact with a MongoDB index (which works fine) and another one using ScalaJS to do the same thing.
Here is my build.sbt :
enablePlugins(ScalaJSPlugin)
name := "demographics"
version := "1.0"
scalaVersion := "2.12.1"
libraryDependencies += "org.mongodb.scala" %% "mongo-scala-driver" % "1.2.1"
libraryDependencies += "be.doeraene" %%% "scalajs-jquery" % "0.9.1"
libraryDependencies += "org.scala-js" %%% "scalajs-dom" % "0.9.1"
skip in packageJSDependencies := false
jsDependencies +=
"org.webjars" % "jquery" % "3.1.1" / "3.1.1/jquery.js"
and my main file:
package demographics.webapp
import org.mongodb.scala._
import scala.scalajs.js.JSApp
object DemographicsApp extends JSApp {
def main(): Unit = {
// connect to the bdd
val mongoClient: MongoClient = MongoClient()
val database: MongoDatabase = mongoClient.getDatabase("demographics")
val collection: MongoCollection[Document] = database.getCollection("demographics")
}
}
Very basic: just connect to the collection.
Sadly, when I launch a "fastOptJS" on the sbt shell, the following error appears:

The same code (with adaptations in the main file) is working on the vanilla Scala project, why this error appears?
It appears because you use a JVM-only library. mongo-scala-driver is not published for Scala.js. It it were, you could use a %%% dependency to depend on the Scala.js version of that library, which would work with Scala.js. But you cannot use a JVM-only library in a Scala.js project.
(Conversely, you cannot use a Scala.js-only library in a Scala/JVM project, for example, scalajs-dom.)
I am getting a bunch of linker errors when trying to link to FastParse in a Scala project which I've just tried to build a ScalaJS web app in.
I added the ScalaJS dependency for FastParse into my build.sbt: here's approximately the relevant line (full file here):
libraryDependencies ++= Seq(
"com.lihaoyi" %%% "fastparse" % "0.4.1"
)
My errors are voluminous, but here's a representative one:

What am I doing wrong?
The problem was that I was requiring the JVM version of FastParse two lines up in my build.sbt. This broke my build apparently. I removed that line and cleaned my build and now both the ScalaJS and ScalaJVM versions of the project are building nicely.
(Thanks heaps to Li Haoyi for spotting the problem for me)
I'm having my apis in play 2.3 with reactive mongo. Recently, i tried to cleaned the project and during the process, some things got updated. Later, when i tried to run or compile that, i'm getting these errors. Apart from clean, i didn't do anything. Kindly help me.

Thanks,
Your version of Play is not compatible with the newest Snapshot of Play Reactive Mongo. You could just use Version 0.10.5.
Add this to your Library Dependencies
"org.reactivemongo" %% "play2-reactivemongo" % "0.10.5.0.akka23"
I have the following spec:
import org.specs2.mock.Mockito
import org.specs2.mutable.Specification
class LinkUserServiceSpec extends Specification with Mockito {
val linkUserService = mock[LinkUserService]
"The 'LinkUserService' isUserLinked method" should {
"return false when a previously unlinked userId is passed in for a given service" in {
linkUserService.isUserLinked("nobody", "YT") returns false
linkUserService.isUserLinked("nobody", "YT") must beFalse
}
}
}
And the following dependency in my build.sbt:
"org.specs2" %% "specs2" % "2.2" % "test"
However I get this error when I type test into the sbt console:
[error] bad symbolic reference. A signature in MocksCreation.class refers to type MockSettings
[error] in package org.mockito which is not available.
[error] It may be completely missing from the current classpath, or the version on
[error] the classpath might be incompatible with the version used when compiling MocksCreation.class.
[error] bad symbolic reference. A signature in MockitoStubs.class refers to term stubbing
[error] in package org.mockito which is not available.
[error] It may be completely missing from the current classpath, or the version on
[error] the classpath might be incompatible with the version used when compiling MockitoStubs.class.
[error] two errors found

Anyone know what this could be?
Apparently if you want to use Mockito with Specs2 you have to provide the dependency yourself, I added the following to my build.sbt and things started working:
"org.mockito" % "mockito-all" % "1.9.5"
