custom JForum, develop error

[Migrated From Jforum.net]

I want to custom JForum.

1. I can't connect to CVS, it said no "guest/jforum".

2. So, I build the Eclipse workspace manaully. I add some JBoss jar files into lib. But I still have one error.

[javac] C:\JForum-2.1.4\src\net\jforum\view\forum\PostAction.java:778: deleteTopic(int,int,boolean) in net.jforum.view.forum.common.TopicsCommon cannot be applied to (int,int)
    [javac] TopicsCommon.deleteTopic(p.getTopicId(), p.getForumId());

I find the declaration

public static void deleteTopic(int topicId, int forumId, boolean fromModeration) throws Exception

Why I have this error ?

Thanks
