object xml is not a member of package scala

Question

The following code in the compiler:

abstract class query {def get: Unit => scala.xml.Elem}

gives me the error: "object xml is not a member of package scala"

however when I use scala.xml.Elem in sbt through the command line it works just fine,

how do I fix this?

Thanks in advance

Answer 1

Scala-XML has been factored out into a separate library as of Scala 2.11, so it is not included in Scala projects by default. To include it in your project via sbt add this dependency:

libraryDependencies += "org.scala-lang.modules" %% "scala-xml" % "1.0.2"

Answer 2

(This is for Windows at least)

In Eclipse go to

Project > Properties

On the windows that appears (should be on Java Build Path on the left) choose the "libraries" section and click on "Add External JARs".

Navigate to your installation folder and then to the "lib" folder (usually

C:\Program Files (x86)\scala\lib

or

C:\Program Files\scala\lib

)

and add

scala-xml_2.11-1.0.2

or whatever version you have.

Answer 3

Update the dependency

// https://mvnrepository.com/artifact/org.scala-lang.modules/scala-xml_2.12
libraryDependencies += "org.scala-lang.modules" % "scala-xml_2.12" % "1.0.6"
