[Building Sakai] how to build appbuilder project in eclilpse?

[wendy lee]

hi, all

I create a helloworld project with appbuilder0.88 in eclipse. Building and deploying successfully with mvn in commandline, and I can run in tomcat too.
Now I want to change the helloworld project to adding more codes. I realize that the .classpath has user-api and entity-api. Where does these two api projects exists? I can't find them in the src2.8   

thx
