make gradle display_name property use full dependency name

closes #3353

Thanks for tackling this!

What you've got looks good, but I realized while reviewing that these can be quite verbose, so we'll probably need to cap a max length... should be trivial to implement, but gimme a day or two to collect more info for #3353 (comment).

@mrwhoknows55 want to pick one of these solutions and run with it?:

So there's a lot of variables there, but if we just cap max length of the full dependency name at 100 chars that's probably good enough.

For when it's over 100 chars, then if we want to get fancy, truncate the path, ie full-pa../package-name. But given that will be rare, the simpler option is to punt and if longer then 100 chars revert back to current behavior of only displaying package name. I'm personally fine either way, we can always further improve it later if needed.

Looks great, thanks!

Can you fix the lint failures? https://github.com/dependabot/dependabot-core/actions/runs/4025933944/jobs/6925118702

For the line too long, I'm fine if you disable that check for that line, IMO the point is to have a long package name...

method(argument) # rubocop:disable Layout/LineLength

I suspect the smoke test failure is because the smoke test needs updating to match the new expected behavior--I can handle that post merge.

[jeffwidman]

I went ahead and fixed the lints so we could land this.

I fixed the failing smoke test in dependabot/smoke-tests#27.
