Gradle wrapper not working without defining a wrapper task in 1.10

Trying to do gradle wrapper with 1.10 but I get the following error:

FAILURE: Build failed with an exception.

  • What went wrong: Task ‘wrapper’ not found in project ‘:blah’.

  • Try: Run gradle tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 4.84 secs

It works if a define a wrapper task and set the gradleVersion to 1.10

I thought you were suppose to be able to do just gradle wrapper since 1.7 without having to define a task. The docs for latest (1.10) suggests you need to define the wrapper task as well.
