使用nailgun时Scala编译服务器错误

Question

我目前正在使用IntelliJ Idea 13.0 Build 132.197,我在构建任何Scala项目时经常遇到这个问题

6:08:42 PM Scala compile server: java.net.BindException: Address already in use: JVM_Bind
    at java.net.DualStackPlainSocketImpl.bind0(Native Method)
    at java.net.DualStackPlainSocketImpl.socketBind(DualStackPlainSocketImpl.java:106)
    at java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:376)
    at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:190)
    at java.net.ServerSocket.bind(ServerSocket.java:376)
    at java.net.ServerSocket.(ServerSocket.java:237)
    at com.martiansoftware.nailgun.NGServer.run(Unknown Source)
    at java.lang.Thread.run(Thread.java:724)

当我只打开一个项目,并且在任何其他进程中不使用nailgun时,会发生此错误.关闭并重新打开项目不起作用.退出IntelliJ并重新启动后,我仍然遇到相同的错误.

在Windows任务管理器中,我看到一个java.exe包含以下详细信息的进程:

E:\Dev\Java\bin\java -cp "E:/Dev/Java/lib/tools.jar;C:/Program Files (x86)/JetBrains/IntelliJ IDEA 132.197/lib/jps-server.jar;C:/Program Files (x86)/JetBrains/IntelliJ IDEA 132.197/lib/trove4j.jar;C:/Program Files (x86)/JetBrains/IntelliJ IDEA 132.197/lib/util.jar;C:/Users/hanxue/.IntelliJIdea13/config/plugins/Scala/lib/scala-library.jar;C:/Users/hanxue/.IntelliJIdea13/config/plugins/Scala/lib/scala-plugin-runners.jar;C:/Users/hanxue/.IntelliJIdea13/config/plugins/Scala/lib/jps/nailgun.jar;C:/Users/hanxue/.IntelliJIdea13/config/plugins/Scala/lib/jps/sbt-interface.jar;C:/Users/hanxue/.IntelliJIdea13/config/plugins/Scala/lib/jps/incremental-compiler.jar;C:/Users/hanxue/.IntelliJIdea13/config/plugins/Scala/lib/jps/jline.jar;C:/Users/hanxue/.IntelliJIdea13/config/plugins/Scala/lib/jps/scala-jps-plugin.jar" -Xmx1024m -server -Xss1m -XX:MaxPermSize=256m org.jetbrains.plugins.scala.nailgun.NailgunRunner 3200

这是因为Nailgun设置的问题吗？

Answer 1

以下是这种情况的手动解决方案:

• 找到在端口3200上侦听的进程(PID)(在设置> scala> tcp端口中检查它)
  • 在Mac(Linux)上: lsof -i :3200
• 检查那个过程
  • 在Mac(Linux)上: ps axu |grep <PID>
  • 在我的情况下,它结束了 org.jetbrains.plugins.scala.nailgun.NailgunRunner 3200
• 杀死这个过程,这是一个旧的过程,IDEA将启动新的过程
  • 在Mac(Linux)上: kill -9 <PID>
