Uses the javadoc tool for generating javadocs for the specified project.

Plugin coordinates:

• Group Id: org.apache.maven.plugins
  
• Artifact Id: maven-javadoc-plugin
  

Plugin Prefix: javadoc

The javadoc plugin has the following goals:

• help: Display help information on maven-javadoc-plugin.
  
  
• jar: Bundles the Javadoc documentation for main Java code in an NON aggregator project into a jar using the standard Javadoc Tool.
  
  
• test-jar: Bundles the Javadoc documentation for test Java code in an NON aggregator project into a jar using the standard Javadoc Tool.
  
  
• javadoc: Generates documentation for the Java code in an NON aggregator project using the standard Javadoc Tool.
  
  
• test-javadoc: Generates documentation for the Java Test code in an NON aggregator project using the standard Javadoc Tool.
  
  
• javadoc-no-fork: Generates documentation for the Java code in an NON aggregator project using the standard Javadoc Tool. Note that this goal does require generation of sources before site generation, e.g. by invoking mvn clean deploy site.
  
  
• test-javadoc-no-fork: Generates documentation for the Java Test code in an NON aggregator project using the standard Javadoc Tool. Note that this goal does require generation of test sources before site generation, e.g. by invoking mvn clean deploy site.
  
  
• aggregate-jar: Bundles the Javadoc documentation for main Java code in an aggregator project into a jar using the standard Javadoc Tool.
  
  
• test-aggregate-jar: Bundles the Javadoc documentation for Java Test code in an aggregator project into a jar using the standard Javadoc Tool.
  
  
• aggregate: Generates documentation for the Java code in an aggregator project using the standard Javadoc Tool.
  
  
• test-aggregate: Generates documentation for the Java Test code in an aggregator project using the standard Javadoc Tool.
  
  
• aggregate-no-fork: Generates documentation for the Java code in an aggregator project using the standard Javadoc Tool.
  
  
• test-aggregate-no-fork: Generates documentation for the Java Test code in an aggregator project using the standard Javadoc Tool.
  
  
• resource-bundle: Bundle AbstractJavadocMojo.javadocDirectory, along with javadoc configuration options.
  
  
• test-resource-bundle: Bundle TestJavadocJar.testJavadocDirectory, along with javadoc configuration options.
  
  
• fix: Fix Javadoc documentation and tags for the Java code for the project.
  
  
• test-fix: Fix Javadoc documentation and tags for the Test Java code for the project.
  

The goal help gives general information about the javadoc plugin and lists its goals.
The parameter detail gives detailed information about the parameters of the goals of the javadoc plugin.
$ mvn javadoc:help $ mvn javadoc:help -Ddetail=true
If you need to use the plugin's coordinates instead of its prefix, you can do that as following:
$ mvn org.apache.maven.plugins:maven-javadoc-plugin:3.4.1:help $ mvn org.apache.maven.plugins:maven-javadoc-plugin:3.4.1:help -Ddetail=true
You can also use the goal describe of the help plugin to get information about the javadoc plugin and lists its goals:
$ mvn help:describe -Dplugin=javadoc $ mvn help:describe -Dplugin="org.apache.maven.plugins:maven-javadoc-plugin:3.4.1" $ mvn help:describe -Dplugin="org.apache.maven.plugins:maven-javadoc-plugin:3.4.1" -Ddetail=true
The parameter goal gives information about a goal of the javadoc plugin:
$ mvn javadoc:help -Dgoal=javadoc -Ddetail=true $ mvn help:describe -Dplugin=javadoc -Dgoal=javadoc -Ddetail=true

Adjust your pom file with the following:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <version>3.4.1</version> <executions> <execution> <id>javadoc</id> <phase>package</phase> <goals> <goal>jar</goal> <goal>test-jar</goal> </goals> </execution> </executions> </plugin>
