Lots of false positive under "Unused dependencies" : project doesn't compile anymore when removed

BUILD SUCCESSFUL in 18s

Describe the bug

To Reproduce Steps to reproduce the behavior:

1. Use ./gradlew buildHealth
2. Get advice :

Advice for :core-network:core-network
Unused dependencies which should be removed:
  implementation(libs.rxjava2.rxjava)
  implementation(libs.threetenabp)

3. Follow advice, remove the 2 lines
4. Rebuild (./gradlew :core-network:core-network:assembleDebug)
5. Build fails :

> Task :core-network:core-network:compileDebugKotlin FAILED
e: file:///C:/Work/lapresse/LaPresse/core-network/core-network/src/main/kotlin/org/openapitools/client/infrastructure/LocalDateAdapter.kt:8:12 Unresolved reference: threeten
(...)

Expected behavior Build should not fail after follow an advice

Is that all of the advice? Or is there more, like used transitive advice?

[MJ-Hayden]

I'd guess this is because ignoring used transitive dependencies doesn't seem to be taken into account by the unused dependency reporting. In this case, the report states that a dependency is unused because the module is using a transitive but doesn't report the transitive info because it's turned off.

Would it be possible to update the unused dependency report to consider whether used transitives are ignored?
