As it was mentioned here:

Baseline profiles also participate in the obfuscation process.

This works well for application (app bundle), but it was turned out, this doesn't work for library (aar).

Please, check out the demo project. It contains 3 modules: app, sdk and baseline-profile. Modules app and sdk are both configured to be built with Baseline Profile.

Build App Bundle:

./gradlew :app:generateReleaseBaselineProfile :app:copyBaselineProfile
./gradlew :app:bundleRelease

Build AAR:

./gradlew :sdk:generateReleaseBaselineProfile :sdk:copyBaselineProfile
./gradlew :sdk:build

Then open ./app/build/outputs/bundle/release/app-release.aab in Android Studio and check two files - classes.dex and baseline.prof - both have obfuscated classes, everything is well, as expected.

Then open ./sdk/build/outputs/aar/sdk-release.aar in Android Studio and check two files - classes.jar and baseline-prof.txt - the first one has obfuscated classes, but the second one have not!

Expected state: classes & methods in baseline-prof.txt must be obfuscated according to classes.jar.
