How to disable Javadoc warnings in Maven Javadoc Plugin?

Since version 3.0.0 of the maven-javadoc-plugin you can use the doclint configuration parameter. If you just want to disable the “missing” warnings, use all,-missing:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>3.0.1</version>
    <configuration>
        <doclint>all,-missing</doclint>
    </configuration>
</plugin>

For more information see the doclint parameter documentation.
