Let's consider updating the checkstyle version in that case.

only later version of checkstyle support the """ style (java 15+), and had to exclude this file since the error thrown was parsing error. in the later version of checkstyle a bunch of other things failed as well, so prefer to make checkstyle a separate pr besides this one.

Okay, thanks for the details.
I think you can also use
// CHECKSTYLE.OFFto turn off checkstyle without having to exclude the entire file in pom. e.g. seeStringUtilsclass.There was a problem hiding this comment.

it still complains about error, i think parsing was before style check

I see, thanks for checking. Let's just exclude it in the pom until we upgrade the checkstyle version in the follow up PR.
