在 IntelliJ IDEA 中使用 fsc 编译服务器永远不会完成构建

Question

我一直在尝试使用 FSC 构建 IntelliJ，如下所述：

http://grahamhackingscala.blogspot.com/2010/10/turn-fsc-fast-scala-compiling-on-in.html

我已完全按照所有说明进行设置启动运行配置。当我运行时，会发出此命令。

/usr/bin/java -verbose -Denv.classpath="%CLASSPATH%" -Denv.emacs="%EMACS%" -Dfile.encoding=UTF-8 -classpath /opt/local/share/scala-2.8/lib/scala-compiler.jar:/opt/local/share/scala-2.8/lib/scala-library.jar scala.tools.nsc.CompileServer

我传递了 -verbose 参数，然后我就可以看到正在加载的内容。以下是最后 10 行输出：

[Loaded java.net.Socket from /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Classes/classes.jar]
[Loaded com.apple.java.Usage$3 from /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Classes/classes.jar]
[Loaded com.apple.java.Application from /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Classes/classes.jar]
[Loaded com.apple.java.Application$1 from /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Classes/classes.jar]

[Loaded java.util.Collections$UnmodifiableMap from /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Classes/classes.jar]

即使在一小时之后，它也不会超出此点。我对Scala完全陌生，而且对Java几乎一无所知，所以我在这里没有任何线索。如果有帮助的话，我很乐意提供更多信息，但目前，这就是我能提供的全部信息。

也许您遇到了已知错误 http://youtrack.jetbrains.net/issue/SCL-2271

解决方法是手动启动 fsc，

您也有可能会被 http://youtrack.jetbrains.net/issue/SCL-2409

对于这个，你最好设置一个脚本，每半小时重新启动一次 fsc
