> h3. CURRENT BEHAVIOR:
> When using Java 11 (or newer versions) the Javadoc generation step fails with the error:
> {{[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.8.1:jar (build-and-attach-javadocs) on project mesos: MavenReportException: Error while creating archive:}}
> {{[ERROR] Exit code: 1 - javadoc: error - The code being documented uses modules but the packages defined in http://download.oracle.com/javase/6/docs/api/ are in the unnamed module.}}
> {{[ERROR]}}
> {{[ERROR] Command line was: /usr/lib/jvm/java-11-openjdk-amd64/bin/javadoc @options}}
> {{[ERROR]}}
> {{[ERROR] Refer to the generated Javadoc files in '/home/admin/mesos-deb-packaging/mesos-repo/build/src/java/target/apidocs' dir.}}
> {{[ERROR] -> [Help 1]}}
> {{[ERROR]}}
> {{[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.}}
> {{[ERROR] Re-run Maven using the -X switch to enable full debug logging.}}
> {{[ERROR]}}
> {{[ERROR] For more information about the errors and possible solutions, please read the following articles:}}
> {{[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException}}
> {{make[1]: *** [Makefile:17533: java/target/mesos-1.11.0.jar] Error 1}}
> {{make[1]: Leaving directory '/home/admin/mesos-deb-packaging/mesos-repo/build/src'}}
> {{make: *** [Makefile:785: all-recursive] Error 1}}
> *NOTE:* The error is at the Maven javadoc plugin call when it tries to include references to the non-existant old Java 6 documentation.
> h3. POSSIBLE SOLUTION:
> Just remove the old reference with adding <detectJavaApiLink>false</detectJavaApiLink> to the  javadoc maven plugin configuration section
