Why is it that CI tools don't make warnings visible? Why are they ignored by default in the first place? Seems like that should be a rather high priority.
It isn't that easy. If you have a new warning on upgrade you probably want to work on it "next week", but that means you need to ignore it for a bit. Or you might still want to support a really old version without the new API and so you can't fix it now.
Most of the time they don't matter and aren't an immediate problem.
The Business doesn't care about warnings, they want working software NOW.
> Why is it that CI tools don't make warnings visible?
A developer setting up CI decides to start an ubuntu 24.04 container and run 'apt-get install npm'
This produces 3,600 lines of logging (5.4 log lines per package, 668 packages) and 22 warnings (all warnings about man page creation being skipped)
Then they decide "Nobody's going to read all that, and the large volume might bury important information. I think I'll hide console output for processes that don't fail."
Now your CI doesn't show warnings.
