How to detect which gradle project that contains classes that have dependency on an updated class?

Question

For example if I have class A1 in project A, B1 in project B, C1 in project C, and D1 in project D. Both class A1 and C1 have dependency on class D1. When I updated class D1 I want to track which projects contains A1 and C1. The objective is that I want to only build project A, C, and D on my CI.

PS: I use monorepo
