Subject [jira] [Commented] (MJAVADOC-480) Javadoc generation broken on Java9 if there are references to javax.xml.bind.annontation.XmlElement and building code for java8
Date Mon, 08 May 2017 18:34:05 GMT

    [ https://issues.apache.org/jira/browse/MJAVADOC-480?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16001282#comment-16001282

Robert Scholte commented on MJAVADOC-480:
-----------------------------------------

Thanks for the confirmation. This would be a valid usecase to introduce a profile:

{code:xml}
<profile>
      <activation>
        <jdk>[9,)</jdk>
      </activation>
      <build>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-javadoc-plugin</artifactId>
            <configuration>
              <additionalparam>--add-modules ALL-SYSTEM ${additionalparam}</additionalparam>
            </configuration>
          </plugin>
        </plugins>
      </build>
    </profile>
{code}

I don't think we should do some magic in this plugin to resolve this, the developer should
be aware of this setup.
However, let's add a FAQ or example page for it.
