Currently(sbt 1.4.1) if sbt is not run manually the work on a large project is not possible with bsp.
if bsp server is not run intelliji idea will run it by the following command(from .bsp/sbt.json):
usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java -Xms100m -Xmx100m -classpath /usr/share/sbt/bin/sbt-launch.jar xsbt.boot.Boot --bsp
The running server always uses the default jvm options:
ps -a -o pid,user,%mem,command | grep java 76504 admin 5.3 java -Xms2048M -Xmx2048M -Xss2M -jar /usr/share/sbt/bin/sbt-launch.jar
So a compilation for a large project is not possible because of out of memory.
I have tried to use:
- build.sbt(sbt Reference Manual — Forking)
Global / javaOptions += "-Xmx8G" Zero / javaOptions += "-Xmx9G" run / javaOptions += "-Xmx10G" javaOptions += "-Xmx11G"
Currently I have not managed to find a work solution.
It seems that sbt must always be run manually currently.
