How do you use external Scala compiler with IDEA 12? -


how use external scala compiler idea ? seem have randomly appearing errors saying "scala: cannot connect compile server @ localhost/127.0.0.1:3200"

sometimes works. doesn't. can't find pattern.

here have in log

9:20:58 pm auto make completed errors 9:21:09 pm using new (sbt-based) scala compiler.            in case of compilation problems may enable previous (internal) compiler clearing:            project settings / compiler / use external build 9:21:10 pm scala compile server            error: not create java virtual machine.            error: fatal exception has occurred. program exit.  9:21:12 pm compilation completed 1 error , 0 warnings in 3 sec

i'm using

  • idea 12.1 (129.161)
  • scala compiler 2.10.1
  • scala plugin 0.7.213
  • jdk 1.7
  • windows 7

in project settings / compiler / use external build checked. in ide settings / scala / run compile server checked.

do need launch compiler server manually ? else ?

upd: looks bug me. posted jira ticket http://youtrack.jetbrains.com/issue/scl-5523

you need lower heap size 1024 512 or something. compile server can created , started. tried intelij 13.0.2 (133.331) , scala plugin 0.26.361
