Sample code to create a site in liferay (don't do this)

SiteCreator.java

public class SiteCreator {

    public static void createGroup() throws Exception {

        // Don't do this!

        long groupId = CounterLocalServiceUtil.increment(Group.class.getName());

        Group group = GroupLocalServiceUtil.createGroup(groupId);
        group.setName("Test Site");
        group.setDescription("This is a test site");
        group.setFriendlyURL("/test-site");
        // Set a bunch of other properties

        GroupLocalServiceUtil.addGroup(group);

        long layoutSetId = CounterLocalServiceUtil.increment(LayoutSet.class.getName());

        LayoutSet layoutSet = LayoutSetLocalServiceUtil.createLayoutSet(layoutSetId);
        layoutSet.setGroupId(groupId);
        layoutSet.setPrivateLayout(false);
        layoutSet.setThemeId("classic");
        layoutSet.setColorSchemeId("01");
        // Set a bunch of other properties

        LayoutSetLocalServiceUtil.addLayoutSet(layoutSet);

        long resourcePermissionId = CounterLocalServiceUtil.increment(ResourcePermission.class.getName());

        ResourcePermission resourcePermission = ResourcePermissionLocalServiceUtil.createResourcePermission(resourcePermissionId);
        resourcePermission.setName(Group.class.getName());
        resourcePermission.setPrimaryKey(groupId);
        // Set a bunch of other properties

        ResourcePermissionLocalServiceUtil.addResourcePermission(resourcePermission);

        // Continue on with other objects, properties as needed until you get the job done...
    }

}

Why did you write "don't do this"?
Is there a better way to create a site/group programmatically?
