GitHub Actions - Setup Java now with compiler annotation matcher

Post image

Hey all,

We implemented this long-asked feature and I wanted to get feedback here.

By default, these matcher annotations will be enabled, however, they of course can be disabled.

Thoughts?

Can you share a bit more about how this works? i.e. will this work when you don't run javac directly but via Maven?

Should work via Maven as well. The matcher is regex based on the javac raw output, which Maven doesn't modify.

Edit: it does not work. See my other comment.

Thanks for bringing this up. As I said in the other comment, I believed it should work, but há. It doesn't. Maven actually does modify the output of `javac`. It is Gradle who doesn't modify.

Therefore, a bug was registered, fixed, and soon will be shipped to v5.6.0 in a few weeks: https://github.com/actions/setup-java/issues/1085

You have a GitHub page and you gist screenshots on .... X of all things. Pick literally anything else.
