FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':minifyReleaseWithR8'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.R8Task$R8Runnable
   > Compilation failed to complete

Solution

From the POM it looks like there's an outdated dependency on androidx viewmodel 2.0.0, because adding:

implementation("androidx.lifecycle:lifecycle-viewmodel:2.8.7")

fixes the issue. The CreationExtras class the API is non-existent on the default classpath coming from the POM. I wonder if there might be a compileOnly dependency when places is getting built. From the release notes it looks like minimum 2.5.0 is needed.

Workaround

If you want to keep viewmodel dependency low, the probably it's worth adding a -dontwarn class com.google.android.libraries.places.internal.zzls rule to the places consumer proguard file.
