How to work around the stricter Java 8 Javadoc when using Maven

For now, the easiest way I know to work around the stricter Java 8 Javadoc when using Maven is deactivating it.

Since the parameter -Xdoclint:none only exists in Java 8, defining this parameter breaks the build for any other Java. To prevent this, we can create a profile that will be active only for Java 8, making sure our solution works regardless of the Java version.

<profiles>
    <profile>
        <id>disable-java8-doclint</id>
        <activation>
            <jdk>[1.8,)</jdk>
        </activation>
        <properties>
            <additionalparam>-Xdoclint:none</additionalparam>
        </properties>
    </profile>
</profiles>

Just add that to your POM and you're good to go.

For maven-javadoc-plugin 3.0.0 users:

Replace

<additionalparam>-Xdoclint:none</additionalparam>

by

<doclint>none</doclint>

Thanks @banterCZ!

If you are using the maven javadoc plugin, you can use the failOnError option to prevent it from stopping if it finds any html errors:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-javadoc-plugin</artifactId>
  <configuration>
    <failOnError>false</failOnError>
  </configuration>
</plugin>

Or you can deactivate the strict html options completely with:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-javadoc-plugin</artifactId>
    <configuration>
      <additionalparam>-Xdoclint:none</additionalparam>
    </configuration>
  </plugin>
</plugins>
