The Solution

Your build.gradle file is defining a task with the name wrapper, likely to pin the gradle version, like:

task wrapper(type: Wrapper) {
    gradleVersion = '5.6.4'

But you have already the gradle wrapper defined in the gradle/wrapper/ file, like:


If you have your gradle wrapper checked-in to source control, you can safely remove the wrapper task from the build.gradle file. Otherwise, remove the file.
