[SOLVED] Compile Server with fsc in IntelliJ IDEA never finishes building

Compile Server with fsc in IntelliJ IDEA never finishes building

I've been trying to get IntelliJ building with FSC, as described here:

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

I've followed all the instructions exactly to set up the Run configuration. When I do Run, this command is issued.

/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

I passed the -verbose argument, then I get to see what's being loaded. Here are the last 10 lines of output:

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

It never progresses beyond this point, even after an hour. I'm completely new to Scala, and I know almost nothing about Java, so I don't have any clues here. I'll be happy to supply more information if that will help, but for now, this is really all I can offer.

Solution

perhaps you're hitting a known bug http://youtrack.jetbrains.net/issue/SCL-2271

the workaround is to start fsc manually

there is a chance that you'll also trip over http://youtrack.jetbrains.net/issue/SCL-2409

for this one you'd better setup a script which restarts fsc every hal an hour
