Grouping Packages

To set a grouping for different packages, use the <groups/> parameter as shown below. Each group will be consist of a <title/> and a <packages/> (as String). The <packages/> element supports wildcard (*) to allow subpackages. If more than one package is to be included, each package name must be separated colon (:) separated (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
