Using Gradle version 4.0 is not allowed but using 6.1, fails to build

[maur0s]

When opening the QR code scanner sample, when opening with the minimum gradle supported version (6.1) fails with the following message:
Cause: org.jetbrains.plugins.gradle.tooling.util.ModuleComponentIdentifierImpl.getModuleIdentifier()Lorg/gradle/api/artifacts/ModuleIdentifier;

Running with 4.0 is not allowed.

Thank you for reporting the issue.

Gradle version in all samples has been updated. Please pull the changes and check if that fixed your problem.
