title: AspectJ not compiling
body: <p>I'm trying to use the metrics-aspectj library (<a href="https://github.com/astefanutti/metrics-aspectj" rel="nofollow noreferrer">https://github.com/astefanutti/metrics-aspectj</a>) to get annotated metrics working in my Dropwizard app, but I am seeing the following exception on startup:</p>
  
  <pre><code>[ERROR] Failed to execute goal org.codehaus.mojo:aspectj-maven-plugin:1.8:compile (default) on project app: AJC compiler errors:
  [ERROR] error Missing message: configure.incompatibleComplianceForSource in: org.aspectj.ajdt.ajc.messages
