fail to run reviewdog: XML syntax error on line 10: expected attribute name in element

@niladrix719 I see that you recreated your PR and it ran fine. That error from reviewdog:

XML syntax error on line 10: expected attribute name in element

indicates it was asked to parse XML, but was passed differently-formatted text. Perhaps the output from bundle exec undercover-checkstyle -c origin/master included some error logging, but reviewdog ate it & so you didn't see it.

The -tee option is very helpful in these cases, as reviewdog will echo out what it was passed. You could add this to your Run reviewdog step definition in .github/workflows/rubyonrails.yml. If you want to revisit a 6-month old PR… reviewdog has had a few releases since then (it was v0.15.0), but hasn't had any significant changes to how it parses XML.

I managed to get a similar error out of reviewdog when my Bundler setup was crummy, and bundle exec printed extra logging. So my guess is that the cache from the ruby/setup-ruby action was corrupted somehow? Quite difficult to tell without the logs from the run.
