对象xml不是包scala的成员 [英] object xml is not a member of package scala

问题描述

编译器中的以下代码：

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

给我的错误：object xml不是包scala的成员

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

然而，当我通过命令行在sbt中使用scala.xml.Elem时，它工作正常，

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

提前感谢

推荐答案

Scala-XML已作为Scala 2.11的单独库计算出来，因此默认情况下不包括在Scala项目中。要通过sbt将其包含在项目中，请添加此依赖项：

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"
