StackOverflowError with Scala on IntelliJ

Question

I am trying to build a Scala project on IntelliJ using Gradle. I am able to make but compile keeps failing with a stack overflow error.

I looked through other posts with similar issues which suggested increasing heap/stack size (this and this). So far I have tried setting these in JAVA_OPTS and idea64.exe.vmoptions.

-Xss512m -Xms512m -Xmx2048m -XX:ReservedCodeCacheSize=64m -ea

I also tried including -XX:MaxPermSize=2048m which didn't work either (believe it is not supported in Java 8 anyway).

The same code builds for another person with the same configuration. Can anyone please shed some light on what I am missing?

Details:

IntelliJ Ultimate 2016.1
Scala 2.10.3
Java 1.8.0_92

This exception is from the compiler process, not the process of IDEA itself. Try to increase -Xss in Settings -> Languages & Frameworks -> Scala Compile Server -> JVM Parameters. Also check that Scala compile server is enabled. — niktrop, Apr 04 '17 at 13:17

The exception is from the compiler that IntelliJ employs, hence you need to change the compiler build process' heap size. Go to

File -> Settings -> Build, Execution, Deployment -> Compiler -> Build process 
heap size (Mbytes)

Increase this property to a higher value.

I've solved this via:

Preferences -> Build, Execution, Deployment -> Compiler -> Scala Compiler -> Scala Compile Server

And updated JVM options to use a bigger stack size, eg: -Xss8m

Restart for the changes to take effect.

Adding -Xss100m in eclipse.ini worked in my case, probably adding similar property in intellijJ may help.

Here is what worked for me:

From Windows Powershell, $env:SBT_OPTS="-Xss1024m" and then ran sbt compile
Also in IntelliJ v2020.2, following also worked: Settings -> Build, Execution, Deployment -> Build Tools -> SBT -> JVM : VM Parameters : -Xss1024m

I had same issues and done lots changes in intellij but non of them work.
