It's failing because the first line of your generated file does not match
the license header (the first line is "Generated from ....").
Interestingly, when I look at my generated files, the first line _is_ the
license file, which is why spotless doesn't fail for me. What's more, I
assume the same is true on Jenkins, otherwise this would be failing on
Jenkins.
However, I think this does show that we're running spotless on generated
code, which is a bug in our spotless setup. It's fragile, and it probably
slows down our spotless runs a lot. I'll take a look right now at excluding
all generated code from spotless.
