title: "IllegalStateException: No files nor directories matching" for non-existing JAR
body: <p>I recently tried to upgrade my Gradle build to SonarQube plugin 2.2 and encountered the following error:</p>
  
  <pre><code>Caused by: java.lang.IllegalStateException: No files nor directories matching '[/opt/bamboo-home/xml-data/build-dir/SPR-SONAR-JOB1/spring-core/build/libs/spring-cglib-repack-3.2.4.jar' in directory /opt/bamboo-home/xml-data/build-dir/SPR-SONAR-JOB1/spring-aop

  <p>This <code>spring-cglib-repack-3.2.4.jar</code> does exist in the <code>spring-core/build/libs/</code> folder, since my build is <a href="https://github.com/spring-projects/spring-framework/blob/518f3fab0192bfaa364b41e55c98d623259b2322/build.gradle#L466" rel="noreferrer">repackaging the cglib dependency</a> in a <a href="https://github.com/spring-projects/spring-framework/blob/518f3fab0192bfaa364b41e55c98d623259b2322/build.gradle#L341-L362" rel="noreferrer">custom jarjar task</a>.</p>
  
  <p>It seems the plugin is looking for that resource under the <code>spring-aop</code> folder, hence the exception.</p>
  
  <p>Note that the same configuration works with the 2.1 version.</p>
