Fluo-234 Sealing jars during release

Either the sonatype one or the apache one might be good. I just lookeda the sonatype one (https://repo1.maven.org/maven2/org/sonatype/oss/oss-parent/9/oss-parent-9.pom), though, and it seems very minimal. It looks like guava has its own parent which inherits from this one, but adds more stuff.
