I have a problem on gradle build

[supercrystal]

FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':runClient'.

Resolving dependency configuration 'runtimeOnly' is not allowed as it is defined as 'canBeResolved=false'.
Instead, a resolvable ('canBeResolved=true') dependency configuration that extends 'runtimeOnly' should be resolved.

I can't find 'runclient' or 'runtimeonly' in build.gradle or settings.gradle
