The annotation processing errors have been eliminated. In the POM, I changed <springdoc.version>1.6.0</springdoc.version> to <springdoc.version>1.8.0</springdoc.version>. One of my coworkers found this fix. I'm not sure where he came up with it, so I can't point to a source. I'm receiving many new errors, but at least these ones are fixed. Thanks to everyone who responded.
