Anyone using incremental kapt in multi-module setup? I’m noticing that it actually makes build times worse if one of core modules is invalidated. For example, changing a feature module causes 70-90 second kapt in the main app module. (Project has over 50 modules)

Are you sure that all your APs are incremental? Maybe some root module has non-incremenral AP

I’ve run with `kapt.verbose` on and didn’t see any non incremental processors.

Usually main module kapt is ~15 seconds without incremental enabled, curious why it would jump to 70-90  seconds with it enabled.

I’ve noticed that with incremental kapt enabled, abi compatible change in a upstream module will cause kapt stubs to invalidate in downstream module. With incremental turned off, it does not invalidate the downstream.
