How do I register a "ProjectCustomizer" to multiple project types?

Use the @Registrations annotation to group the multiple @Registration annotations.

For example

@ProjectCustomizer.CompositeCategoryProvider.Registrations({
    @ProjectCustomizer.CompositeCategoryProvider.Registration(projectType = "org-netbeans-modules-java-j2seproject"),
    @ProjectCustomizer.CompositeCategoryProvider.Registration(projectType = "org-netbeans-modules-web-project"),
    @ProjectCustomizer.CompositeCategoryProvider.Registration(projectType = "org-netbeans-modules-maven")
})
public class MyPluginPanelProvider implements ProjectCustomizer.CompositeCategoryProvider {
//...
}
