Plugin becomes very heavy with large projects

[borissmidt]

Dear,

It seems that this plugin becomes super heavy for projects with 50+ modules, the key references grows per scala version added to the project.

Maybe there are some plugins i could cut but it seems that i have to fall back to the vanilla cross compilation or i can't import the project anymore.

or i can't import the project anymore.

Could you clarify what you meant here? Are you saying that IDE import becomes too slow to be usable? If so which IDE is it?

[borissmidt]

I'm using intellij,
The heaviness i'm talking about is that i already need a 3GB of ram to import a project with 120 projects and this plugin enabled to compile fo scala 2.12, 2.13, 3

The only extra plugin i have enabled is the sbt.protoc plugin.

I'll spend some time to take a heapdump to find what consumes all the memory.

I've made a heapdump and it is mainly Scopes. So i think the project just became exponentially too big with this plugin.
I.e. i had to cross build between 3 scala versions for 100 projects. Where the basic project with normal crossbuild configuration already uses 95068 settings keys.

Maybe it would be a good idea to dynamically calculate the settings keys for each scala version. But this would probably be slow and not fitting the sbt model.
