Smooth!

It should be possible to configure a global "Use FSC" so one doesn't have to loop thru all your modules enabling it for each one.

I tried enabling FSC for my fairly large multi-module Maven project, and once again I get the dreaded "Compiler internal error. Process terminated with exit code 1".

idea.log is useless:

I'm on 1407 already... This is a pretty old symptom, I've been seeing it for years but never managed to pin down a common cause.

not working for me:

Information:Compilation completed with 4 errors and 0 warnings
Information:4 errors
Information:0 warnings
Error: error while loading package, class file 'S:\tools\scala builds\scala-2.9.1.final\lib\scala-library.jar(scala/package.class)' is broken
Error:(class java.lang.NullPointerException)
Error: error while loading Class, class file 'S:\Program Files\Java\jdk1.6.0_20\jre\lib\rt.jar(java/lang/Class.class)' is broken
Error:

any ideas?

set everything to 2.9.1 final, but i still get:

http://ea.jetbrains.com/browser/ea_reports/296974

still not working, i'm back at the original NPE without stacktrace (used 2.9.1 everywhere). it doesn't seem to matter which jdk is set in the project settings. is there a log that i could switch on which tells me more?

i tried both 1.6 and 1.7 and different scala versions - same error everywhere

i'm getting the NPE, no matter what i do. anything i can do to get more information?

I just created a project from scratch with default options selected. I let the IDE create the global compiler library based on my Scala 2.9.1 home directory, enable FSC. But same error. I'm using a 64-bit JDK, could that be the problem?

I really like the internal fsc, but I don't need to be notified everytime it starts and stops

Please remove!

Thanks, Nick.

I’m finding it impossible to get rid of the “Compiler internal error. Process terminated with exit code 1″ error. Non-fsc compile works fine. idea.log has nothing useful in it. I’m on IntelliJ 10.5.2 with Scala plugin 0.4.1440. My project appears to be identically configured to that of a coworker who is using fsc just fine. I’m on Windows, he’s on OSX.

There is nothing on the net that offers any answers. I see a lot of you are using Scala 2.9, but it works fine on my coworkers computer with Scala 2.8.1.

Any thoughts?

Yes, that would help.

I will also try to repro with a fresh install in a virtual machine. At this point I've tried a billion variations of options and can't get it to work on my dev machine, so a fresh virtual machine would be a good approach.

I do have whitespace in my path. I will remove the whitespace and report on whether or not it fixed the problem.

I removed the whitespace, now it works! I'm excited, I finally get to use fsc

The problem is fixed.

I'm having mixed results with my Maven 2.9.1 projects. On a single module project I can start the FSC and get the compliation to work (really sweet). However on my larger project (with multiple modules, some in Scala, some in Java, some POM, and scala definition on the main POM), I can't start the compiler and get an every whenever at least one module uses FSC (internal):

Internal error (Plugin: org.intellij.scala): None.get

I have no white space on the path I'm running IDEA 10.5.2 with plugin 0.4.1461.

On the logs I see the following error:

My "apparent" configuration is the same, but I still fail to compile using FSC. All my modules have the scala facet (including the Parent which defines the scala versions).

I notices on the project's library list the scala-compiler-bundle is grayed. Don't know the meaning of this. I really don't get what is wrong. Is there any way to debug the FSC startup? When I click on the status bar icon and select Run nothing happens.

Thanks for any advice.

I just tested out the new FSC support, and it looks like it's working great. IDEA 10.5.2 on Win7 x64.  Thanks!
