运行Scala项目时出错 - 未找到编译器镜像中的类scala.deprecatedInheritance

Question

我是java和Scala的新手。 我已经下载了IntelliJ 13.1，我试图按原样运行这个项目（Goose文本提取器）：https://github.com/GravityLabs/goose

我使用JDK 1.7.0_67进行这些项目结构设置：

当我试图运行文件TalkToMeGoose.scala我得到这个错误：

Answer 1

所以要恢复我的评论：

您应该使用的编译器库是：Maven: org.scala-lang:scala-compiler-bundle:2.9.0-1

我不知道为什么在打开Goose项目时没有创建它。

但你可以自己创建它：

打开库设置，点击例如：Maven: org.scala-lang:scala-library:2.9.0-1，找到系统下载maven库的位置。

然后点击New Project Library，并添加Maven: org.scala-lang:scala-library:2.9.0-1和Maven: org.scala-lang:scala-compiler:2.9.0-1。文件选择器有一个显示隐藏目录的选项，这可能很有用。

然后进入Module设置并将Scala编译器更改为刚刚创建的库。 （出现在库列表中可能需要几秒钟）。 它应该工作正常。

Answer 2

我可以在命令行上使用maven编译goose。它需要Scala 2.9.0。请检查IDEA 13.1使用的Scala编译器的版本。如果存在版本差异，则可能会出现此类错误。请参阅http://grokbase.com/t/gg/scala-ide-user/143ntm6n3p/switching-scala-library-version-to-match-project
