[cortinico]

This fixes the failures on the PR #3727 such as:

    > Could not resolve all files for configuration ':child1:detekt'.
       > Could not resolve io.gitlab.arturbosch.detekt:detekt-cli:1.17.0-RC2.
         Required by:
             project :child1
          > Cannot choose between the following variants of io.gitlab.arturbosch.detekt:detekt-cli:1.17.0-RC2:
              - runtimeElements
              - shadowRuntimeElements
            All of them match the consumer attributes:
