I have a fairly large multi-project (~ 70 projects) Kotlin and Gradle Kotlin DSL based project. I just updated to Kotlin

1.3.20

and now I'm getting

java.lang.OutOfMemoryError: Metaspace

exceptions from the Koltin compiler. I'm also using the

kotlin.parallel.tasks.in.project=true

flag. Is this a known issue & is there a workaround?

@jlleitschuh Yes, revert to 1.3.11 until 1.3.21 fixes it

Is there a youtrack issue?

@jlleitschuh You can find what is planned to be fixed in 1.3.21 there (look at the search query): https://youtrack.jetbrains.com/issues/KT?q=Target%20versions:%201.3.21%20 There's only three marked as critical (the red

C

), one mentioning

*.gradle.kts

Yes, revert to 1.3.11 until 1.3.21 fixes it

May be just disable

kotlin.parallel.tasks.in.project

?
