Answer 1

You can only get groups you manage, and you have to authorize with the user_managed_groups permission.

Most likely, you don´t manage any groups or the Access Token does not include the permission.

Answer 2

As this answer describes, it is unlikely you will ever get permission to do what you want to do.

In short: Facebook will no longer approve user_groups permission for most developers starting from 30 Apr 2015.

How to get posts from Facebook groups using RestFB in Java?

I'm using apptoken to get posts in pages, but when I create the connection using groupeId+"/post" the program says:

    Command execution failed. Process exited with an error: 1 (Exit value: 1) -> [Help 1]
