sbt未解析依赖: scala解析器组合器

Question

我正在我的scala项目中尝试使用scala解析器组合器。我项目中唯一的.sbt文件是.sbt文件。

libraryDependencies += "org.scala-lang.modules" %% "scala-parser-combinators" % "1.0.4"

我尝试将这一行添加到build/project.sbt中

    resolvers += "Typesafe Repo" at "http://repo.typesafe.com/typesafe/releases/"

但我也得到了同样的错误。

当我从项目根目录中的终端执行sbt时，会获得以下依赖错误(这是错误之前的最后一行)：

[warn]  ::::::::::::::::::::::::::::::::::::::::::::::

[error] (*:update) sbt.ResolveException: unresolved dependency: org.scala-lang.modules#scala-parser-combinators_2.10;1.0.4: not found

有几行代码似乎是sbt试图在几个不同的存储库中解析插件：

为了编写我的project/build.sbt文件，我遵循scala解析器组合器的github储存库提供的指令。

当然，当我没有在project/build.sbt中指定任何内容时，我会从sbt那里得到编译时错误，它不知道Parser类源文件在哪里。

我可以在其中配置project/build.sbt以便使用Scala的解析器组合器库吗？

基于这部分错误：

[warn]  Note: Unresolved dependencies path:
[warn]      org.scala-lang.modules:scala-parser-combinators_2.10:1.0.4 
                                                             ^

看起来您正在使用Scala2.10，其中解析器组合器是标准库的一部分。它们是从Scala2.11的标准库中分离出来的，所以您要寻找的jar不存在。如果您坚持使用2.10，只需删除该依赖项，就可以在标准库中得到它。
