Hi Today - Maven 3.8.6 both exception generate the same message: BUILD FAILURE
We have some inconsistencies in javadocs descriptions [1]. We also have the wrong description on guide page [2]. There was a discussion about it, some on slack, some on GitHub [3] and connected issue MNG-7351 [4] As I remember we want one exception for Mojo in Maven 4. So it will be good to make a decision about it and fix mentioned place to be consistent.
