Increase build memory

[elevenfive]

Fixes build issue with JVM OOM, when user's build environment is not already setting these values to an increased memory amount in ~/.gradle/gradle.properties

In the GitHub action it has always set -Xmx2048m, I don't think it really need -Xmx3072m.

Isn't just this enough? org.gradle.jvmargs=-Xmx2048m

There's kotlin heap and regular heap, which is why it looks duplicated. Will try locally with 2048. Parallel GC is recommended these days, probably should keep that if no disagreement there.

Quote from here:

Currently Kotlin daemon uses the same JVM arguments as Gradle daemon. It is possible to override it in gradle.properties:
org.gradle.jvmargs=-Dkotlin.daemon.jvm.options=-Xmx1500m,-Xms=500m
but it is hard to discover.

So setting it with org.gradle.jvmargs=-Xmx2048m -XX:+UseParallelGC affect both Kotlin and Gradle (if I'm not wrong).

Neat - thank you, didn't realize that!

Confirmed ./gradlew build now works with this change.
