jenkinsci/plugin-pom#869 or a subsequent pull (#465)

request that updates to 4.8.3 will need this change in the plugin to
resolve new spotbugs warnings that will be reported by spotbugs 4.8.2
and later.

Plugin pom 4.77 is likely to include that new version of spotbugs.

Confirmed that the spotbugs warnings are visible when using the
4.77-SNAPSHOT plugin pom before this change. With this change, the
spotbugs warnings are no longer visible.
