title: lein jar to contain both project.clj and pom.xml
body: <p>When I run <code>$ lein jar</code> the created jar file contains a <code>META-INF/maven/groupId/artifactId/project.clj</code> file.</p>
  
  <p>When I run <code>$ mvn package</code> the created jar file contains a <code>META-INF/maven/groupId/artifactId/pom.xml</code>.</p>
  
  <p>How can is setup Leiningen so that both files would be available inside the created jar file? Thank you in advance.</p>
