Building apache hadoop 2.6.0 throwing maven error

Question

When i try to build hadoop 2.6.0 with command

mvn package -Pdist,native,docs -DskipTests -Dtar

I see the below error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.8.1:jar (module-javadocs) on project hadoop-annotations: MavenReportException: Error while creating archive:

 * </ul>

If i go to the source and remove that tag then the build proceed a little further and then again some other tag issue. This is my first ever source compilation. Kindly suggest.

Answer 1

As @Raghuveer already figured it out, a workaround shown below is suggested on their JIRA link https://issues.apache.org/jira/browse/HADOOP-11449

mvn clean package -Pdist -Dtar -Dmaven.javadoc.skip=true -DskipTests -fail-at-end -Pnative

FYI, this issue doesn't happen with hadoop-2.7.0.
