When running gradle multiplatform builds in CI (GitHub Actions), I get the warning

Daemon will be stopped at the end of the build after running out of JVM memory

, then the build hangs. Does anyone know how to enable more memory, and is there any official documentation about how much memory is required by the Multiplatform plugin? Builds without KMP work just fine.

Add

org.gradle.jvmargs=-Xmx4096M

to the root gradle.properties file. Or whatever (larger) amount of memory you want to use.

Thanks Erik, it worked.
