如何使用IntelliJ Idea摆脱scalac ServerException

扬·莫桑（Yann Moisan）

此错误使我无法运行项目。

以下是版本信息：

~ ❯❯❯ java -version

Scala code runner version 2.12.1 -- Copyright 2002-2016, LAMP/EPFL and Lightbend, Inc.

我使用IntelliJ 2016.3

在外部终端和sbt中，它可以工作！

这个问题使我陷入困境

因此，我检查了JDK版本，令人惊讶的是IntelliJ和Nailgun没有在同一JDK上运行。

~ ❯❯❯ ps -ef | grep java
  501  2290  2017   0  4:12PM ??         0:01.81 /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/bin/java … org.jetbrains.plugins.scala.nailgun.NailgunRunner 3200 6a73f540-1a80-476d-96d2-83ab8faaad95
  501  2291  2017   0  4:12PM ??         0:02.15 /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home/bin/java …

因此，我搜索了IntelliJ首选项，发现Scala Compile Server配置了一个旧的JDK：1.8.0_11。im！

我刚刚取消选中了“使用外部编译服务器”复选框
