Error while dexing

[michelesalvador]

Everything worked fine with the release 5 of the library.

Now I downloaded and successfully compiled the example app from this repo, using directly the library code release 7:

implementation project(path: ':library')

So I tried to build the same example app replacing the line above with:

implementation 'com.github.AndroidDeveloperLB:FastScrollerAndRecyclerViewFixes:7'

But this is not possible due to a compiling error:

Execution failed for task ':app:mergeExtDexDebug'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
   > Failed to transform FastScrollerAndRecyclerViewFixes-7.aar (com.github.AndroidDeveloperLB:FastScrollerAndRecyclerViewFixes:7) to match attributes {artifactType=android-dex, asm-transformed-variant=NONE, dexing-enable-desugaring=true, dexing-is-debuggable=true, dexing-min-sdk=24, org.gradle.category=library, org.gradle.dependency.bundling=external, org.gradle.libraryelements=aar, org.gradle.status=release, org.gradle.usage=java-runtime}.

         > Error while dexing.
