This website, https://cwiki.apache.org/MAVEN/maven-3x-plugin-compatibility-matrix.html, says that maven 3 needs the findbugs v2.3 plugin instead of 2.0.1. So I made that change (locally) and ran into this issue:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.0:site (default-site) on project accumulo: failed to get report for org.apache.maven.plugins:maven-javadoc-plugin: Unable to parse configuration of mojo org.apache.maven.plugins:maven-javadoc-plugin:2.5:javadoc: Setter org.apache.maven.plugin.javadoc.JavadocReport.setReportOutputDirectory( java.io.File ) threw exception when called with parameter '/home/medined/Desktop/Dropbox/david/workspace/accumulo/target/site/apidocs': null: InvocationTargetException: NullPointerException -> [Help 1] The directory in question (.../apidocs) did not exist. I created it (just in case) and re-ran the command. But the same error happened.
