Excluding Packages

To exclude specific packages, use <excludePackageNames/> parameter as shown below. The parameter accepts wildcard (*) characters in its value but the wildcards should either be at the start or the end of the package name. If more than one package is to be excluded, each package name must be separated either with a colon (':'), a comma (',') or a semicolon (';'). (similar to the Javadoc Tool)

For instance, with the following packages:

com.mycompany.myapp
com.mycompany.myapp.package1
com.mycompany.myapp.package1.subpackage1
com.mycompany.myapp.package1.subpackage2
com.mycompany.myapp.package1.subpackage3
com.mycompany.myapp.package1.util
com.mycompany.myapp.package2
com.mycompany.myapp.package2.subpackage4
com.mycompany.myapp.package2.subpackage5
com.mycompany.myapp.package2.util
com.mycompany.myapp.package3
com.mycompany.myapp.package3.subpackage6
com.mycompany.myapp.package3.subpackage6.subsubpackage1
com.mycompany.myapp.package3.subpackage6.subsubpackage2
com.mycompany.myapp.package3.subpackage7
com.mycompany.myapp.package3.util

You could have the following configuration:

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-javadoc-plugin</artifactId>
 <version>3.12.0</version>
 <configuration>
 <!--
 Exclude packages:
 com.mycompany.myapp.package1.subpackage1
 com.mycompany.myapp.package1.subpackage2
 com.mycompany.myapp.package1.subpackage3
 com.mycompany.myapp.package1.util
 com.mycompany.myapp.package2
 com.mycompany.myapp.package2.subpackage4
 com.mycompany.myapp.package2.subpackage5
 com.mycompany.myapp.package2.util
 com.mycompany.myapp.package3.util
 BUT include the packages:
 com.mycompany.myapp
 com.mycompany.myapp.package1
 com.mycompany.myapp.package3
 com.mycompany.myapp.package3.subpackage6
 com.mycompany.myapp.package3.subpackage6.subsubpackage1
 com.mycompany.myapp.package3.subpackage6.subsubpackage2
 com.mycompany.myapp.package3.subpackage7
 -->
 <excludePackageNames>com.mycompany.myapp.package1.*:com.mycompany.myapp.package2:com.mycompany.myapp.package2.*:*.util</excludePackageNames>
 </configuration>
</plugin>
