Hey guys, has anyone faced java.lang.OutOfMemoryError: Java heap space when building for testflight on a ComposeMultiplatform project?

[Anton Lakotka [JB]]

Did you enable configuration cache?
if so, try disabling it and check again 🙏

I think I have already did that. this is my gradle.properties file if it helps.

we are just migrating to CMP for our ios client and we rely on some vendor SDKs and a bit of Swift wrappers to call those vendor methods. the project is fairly medium sized.

I have attempted to fix it by giving it 12 gigs of maximum heap size but still fails to build it. (I am on M1 16 gigs)

[Yohannes Tezera]

Anyone?

[Anton Lakotka [JB]]

Perhaps you can try reducing number of subprojects.
And provide memory profiler report

[Yohannes Tezera]

Alright

if anyone cares, I ended up upgrading the machine to a 32 gigs one and then maxxed out all the Java heaps as much as I can.
