Setting in gradle.properties is ignored

[JaFiOriflame]

Hello. I want to ask where do I have the bug. I have compose multiplatform project with multiple modules. I applied all the steps described in the README.md to use flavors. However, the setting in gradle.properties is ignored. I still obtain defaultConfigs values :-( I suppose it is my bug, but I'm not able to find that.

/gradle.properties

#Kotlin
kotlin.code.style=official
kotlin.daemon.jvmargs=-Xmx2048M

#Gradle
org.gradle.jvmargs=-Xmx2048M -Dfile.encoding=UTF-8

#Android
android.nonTransitiveRClass=true
android.useAndroidX=true

buildkonfig.flavor=stg

I print the values into the log in my app:

...
Log.d("HERE env: " + BuildKonfig.env)
Log.d("HERE suffix: " + BuildKonfig.suffix)
Log.d("HERE appLabel: " + BuildKonfig.appLabel)
...

I still obtain this:

HERE env: test
HERE suffix: test
HERE appLabel: test

/gradle/libs.versions.toml

[versions]
...
# BuildKonfig
buildKonfig = "0.15.2"

[plugins]
...
# BuildKonfig
buildKonfig = { id = "com.codingfeline.buildkonfig", version.ref = "buildKonfig" }

Do you see where could be the problem?

I also tried to compile and run the app from command line and the same result:

./gradlew assembleDebug -Pbuildkonfig.flavor=stg
./gradlew installDebug 

Thank you very much.
