Create baseline to detect diff

According to spotbugs this is still possible:
https://spotbugs.readthedocs.io/en/latest/running.html

-excludeBugs :
Exclude bugs that are also reported in the baseline xml output.

Do you think this is hard to add?
Otherwise I would like to give it a try

Hm.
I did this:

• run spotbugs: 100 results
• created baseline xml
• added one "error"
• run spotbugs html: see 101
• run spotbugs with baselineFile -> 0
  --> but here I would have expected 1, the one I added on purpose
