object xml is not a member of package scala
提问by zunior
The following code in the compiler:
编译器中的以下代码：
abstract class query {def get: Unit => scala.xml.Elem}
gives me the error: "object xml is not a member of package scala"
给了我错误：“对象 xml 不是包 scala 的成员”
however when I use scala.xml.Elem in sbt through the command line it works just fine,
但是，当我通过命令行在 sbt 中使用 scala.xml.Elem 时，它工作得很好，
how do I fix this?
我该如何解决？
Thanks in advance
提前致谢

Scala-XML has been factored out into a separate libraryas 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:
自 Scala 2.11 起，Scala-XML 已被分解为一个单独的库，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"

(This is for Windows at least)
（这至少适用于 Windows）
In Eclipse go to
在 Eclipse 中转到
Project > Properties
项目 > 属性
On the windows that appears (should be on Java Build Path on the left) choose the "libraries" section and click on "Add External JARs".
在出现的窗口（应该在左边的 Java Build Path 上）选择“libraries”部分并点击“Add External JARs”。
Navigate to your installation folder and then to the "lib" folder (usually
导航到您的安装文件夹，然后导航到“lib”文件夹（通常是
C:\Program Files (x86)\scala\lib
C:\Program Files (x86)\scala\lib
or
或者
C:\Program Files\scala\lib
C:\Program Files\scala\lib
)
)
and add
并添加
scala-xml_2.11-1.0.2
scala-xml_2.11-1.0.2
or whatever version you have.
或您拥有的任何版本。

Update the dependency
更新依赖
// https://mvnrepository.com/artifact/org.scala-lang.modules/scala-xml_2.12
libraryDependencies += "org.scala-lang.modules" % "scala-xml_2.12" % "1.0.6"

I have the same error, I tried lots of ways. Finally, I found it is the Java Loading dependencies order issue. If I move it to the last one. it works fine for me.
我有同样的错误，我尝试了很多方法。最后发现是Java加载依赖顺序问题。如果我把它移到最后一个。这对我来说可以。
I modify it in my IntelliJ Idea:
cmd-; Project Settings -- Modules -- Dependencies
click + in bottom-left -- 2 Library -- From Maven
我在我的 IntelliJ Idea 中修改它： cmd-; 项目设置——模块——依赖项点击左下角的+——2库——来自Maven
