Atlas-create-bitbucket-plugin-module hangs at "Enter Package Name"

I try to reproduce this tutorial:

to start with an Bitbucket pre repository hook.
The first step of call atlas-create-bitbucket-plugin was working fine.
But the second step call atlas-create-bitbucket-plugin-module fails.
I can enter the Hook type and the Classname for it.
But at the next step “Enter Package Name” the assistant hangs.
I can enter what I will, the question about the package name will only occurs again.

Has somebody an hint?
I use atlassian-plugin-sdk-8.0.7 on CentOS 7.7
