I think it's enough to use a bin distribution type instead instead of all one for Gradle wrapper

A new big fix release is available 8.1.1 and the release notes mention: "We recommend users upgrade to 8.1.1 instead of 8.1."

I would suggest to discard this PR and instead review #13625

[ijuma]

It's a little odd to create a new PR instead of simply updating the one that's open...

[bmscomp]

@ijuma Apologies, may be it's more wise to close the one I created and keep updating this one, I'll update my pull request since it contains also some Gradle plugin upgrades

[ijuma]

In the future, please try to work with the contributor who submitted a PR instead of creating your own. In this case, I went ahead and merged your PR and closed this one.

[bmscomp]

@ijuma Yes of course, I'll do that , this is the first PR ever for me in this repo, I'll keep learning from all of you

[divijvaidya]

Thank you for making this is a teaching moment @ijuma. I will try to do better reviews, keeping in mind your suggestion in future.
