object xml is not a member of package scala
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"
(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.
Update the dependency
