How to disable Javadoc warnings in Maven Javadoc Plugin?

Question

I'm using the Maven Javadoc Plugin. It outputs warnings as follows:

[ERROR] /home/monperrus/spoon/src/main/java/spoon/visitor/CtVisitor.java:144:
      warning: no @param for <T>

How to display those warnings as [WARNING] (and not the confusing [ERROR])?

How to display those warnings as [WARNING] (and not the confusing [ERROR])? How to completely disable Javadoc warnings in Maven?

If you are talking about the javadoc lint warnings introduced in Java 8 then you should be able to do the following. There are multiple ways of specifying the parameters depending on which version of the javadoc plugin you are using.

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

See this good discussion about turning off doclint.

If you are instead just want to get rid of the missing jacadocs warnings then you can use:

<configuration>
   <additionalparam>-Xdoclint:all -Xdoclint:-missing</additionalparam>
   <additionalOptions>-Xdoclint:all -Xdoclint:-missing</additionalOptions>
   <additionalJOptions>
     <additionalJOption>-Xdoclint:all</additionalJOption>
     <additionalJOption>-Xdoclint:-missing</additionalJOption>
   </additionalJOptions>
</configuration>
