Хорошо компилируется ибыстро, и проблема возникла после того, как я изменил некоторые типы возврата нескольких функций.
Впервые проблема возникла:
- Debian Stretch
- scala 2.12.8
- sbt 1.2.8
- java 1.8 (как openjdk, так и oracle jdk)
Я пробовал несколько версий Scala и sbt, но та же проблема. Ошибка может быть воспроизведена на Travis и на Mac OS.
Я не думаю, что здесь проблема с памятью, так как я выделил много:
export SBT_OPTS="-Xms4G -Xmx8G -Xss8M -XX:MaxMetaspaceSize=2G -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC"
Любая идея, что может быть не так или как я мог бы устранить это?
