Thanks for the report!

Root cause: versioned formulas (name@version.rb) were copies of the unversioned formula but kept the same class name, while Homebrew expects ClassNameATversion (e.g. MqCrawlAT0520). That mismatch is what caused the import error.

I've fixed the generator and corrected the class names across the tap. Could you try re-tapping to confirm it's resolved?

Sorry for the noise, and thanks for reporting it!

thank you for the response.

retapping: I ran brew tap harehare/tap and then brew update and all is clean.

on the other hand, i am not sure if this is a good enough test. I guess the next update is the real test?

thanks again for mq; I find it very useful.

Thanks for confirming.

​You're right that the next release is the real test, but I've updated the automation script to ensure future formulas are generated correctly. We should be all good.

​Thanks again for testing it out!
