[BEAM-3715] Explicitly exclude some troublesome optional deps

[kennknowles]

The optional dependencies of elasticsearch-hadoop, pulled in by hadoop-input-format, appear to be getting fetched by Gradle. For some reason we have explicitly excluded three of them (also in the Maven config) even though they should already be left out. To fix the build, this explicitly excludes those that I have seen flake.

• Write a pull request description that is detailed enough to understand:
  • What the pull request does
  • Why it does it
  • How it does it
  • Why this approach
• Each commit in the pull request should have a meaningful subject line and body.

I actually introduced flagrant style violations into master and it has no effect on the spotlessJavaCheck. From what I can tell spotless actually does not do anything in our build at the moment. The checkstyleMain and checkstyleTest are the things that actually check the formatting.

[kennknowles]

Thus having an empty spotless { java { } } versus just applying the plugin, or whatever, doesn't really matter. I would suggest removing the plugin for now unless you know something that is not obvious here.

I think your above comments are for the wrong PR.

Add a TODO with JIRA issue.

Done

Yea, got my tabs mixed up it seems. Lots of gradle fixes waiting.
