在IntelliJ 10.5中配置Scala编译器？

Question

我试图让Scala在IntelliJ 10.5.1中正常工作。 我从“可用插件”设置安装了插件，然后尝试启动一个新的Java项目，在可用技术下选择“scala”。 但是当我尝试运行它时，Scala说我没有在scala方面定义一个scala编译器。 所以我去了那里，但我没有看到任何设置编译器的方法。 另外，我项目中的.iml文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
    <module type="JAVA_MODULE" version="4">
      <component name="FacetManager">
        <facet type="scala" name="Scala">
          <configuration>
            <option name="compilerLibraryLevel" value="Global" />
            <option name="pluginPaths">
              <array>
                <option value="$USER_HOME$/SDKs/scala/src/scala-compiler-src.jar" />
              </array>
            </option>
          </configuration>
        </facet>
      </component>
      <component name="NewModuleRootManager" inherit-compiler-output="true">
        <exclude-output />
        <content url="file://$MODULE_DIR$">
          <sourceFolder url="file://$MODULE_DIR$/src" isTestSource="false" />
        </content>
        <orderEntry type="inheritedJdk" />
        <orderEntry type="sourceFolder" forTests="false" />
        <orderEntry type="library" name="scala " level="application" />
      </component>
    </module>

请注意，它似乎确实指向正确的jar编译器目标。

我需要做什么？

编辑 -

编译器现在正在工作，但是当我运行时，我收到此错误：

Answer 1

转到项目设置（可以通过Ctrl + Alt + Shift + S调用）并在库列表中选择scala-compiler ，如下所示：

现在FacetManager组件如下所示：

<component name="FacetManager">
    <facet type="scala" name="Scala">
      <configuration>
        <option name="compilerLibraryLevel" value="Global" />
        <option name="compilerLibraryName" value="scala-compiler-2.9.0.1" />
      </configuration>
    </facet>
  </component>

请参阅“ 项目配置指南” 。

如果您使用SBT构建，我建议使用sbt-idea生成您的IDEA项目，并使用idea-sbt-plugin将IDEA中的项目编译委托给SBT。

我想你需要将scala编译器库添加到全局库中。 在模块设置 - >全局库 - >附加jar目录并选择scala安装目录下的lib文件夹，然后执行om-nom-nom建议以确保选择编译器。
