Somebody help me .
         After I successful deploy sakai 2.6.2 from the source package with mysql config , I tried out SakaiAppBuilder . So I got Eclipse galimede jee and follow this instruction Development Environment Setup Walkthrough - WG: Programmer's Cafe (with slight differences) . But when I create a new project in Sakai-source folder , I got these error :

and ... missing ... common-logging 1.1.jar -> I firgued out the reference was wrong so I edit it to the right one in my .M2\repository and it seems to work(this error disappear)
but there r 2 more
Project 'HelloWorld' is missing required Java project: 'user-api'   (Type = Build Path Problem)
Project 'HelloWorld' is missing required Java project: 'entity-api' (Type = Build Path Problem)

I saw there's a folder user/user-api inside sakai-source but IT"S EMPTY . I thought there must be some mistake so I issue
"svn co https://source.sakaiproject.org/svn/user/"
 to download the user folder from the repository . Then I checked . And for Sakai 2.6.2 the user/user-api is really empty so I copied all file from the same folder of sakai 2.5 to my 2.6/user/user api and then go to eclipse >project>properties>buildpath>project to make sure the reference is right . Then I refreshed , problem remain, nothing seemed to change .
Plzz SOMEBODY HELP
THANKS
