[yocto] How to do the specified tasks instead of many default ones

[Liu]

Hi all,
     I'm compiling a test package  "helloworld",then I just want to do the standard tasks of "do_fetch","do_unpack" until the task "do_compile",and I do not want to the next tasks like "do_build","do_package". I think there exist the task dependency chain,but can hardly find how to remove the tasks I do not want to do.Can anyone tell me something detailed about this question ?
 Best wishes,
 --------------Liu
