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:

抽象类查询 {def get: Unit =>scala.xml.Elem}

给我错误:对象xml不是scala包的成员"

但是，当我通过命令行在 sbt 中使用 scala.xml.Elem 时，它工作得很好，

我该如何解决这个问题?

提前致谢

解决方案

Scala-XML 已被分解为一个单独的库

a> 从 Scala 2.11 开始，因此默认情况下它不包含在 Scala 项目中.要通过 sbt 将其包含在您的项目中，请添加此依赖项:

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

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

解决方案

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"
