Pypi plugin not working

I am currently trying to use the pypi plugin with drone 1.0.0, but get the following error again and again:

InvalidDistribution: Cannot find file (or expand pattern): 'dist/*'
: exit status 1 

The .drone.yml looks like this:

kind: pipeline
name: default

steps:
- name: pypi
  image: plugins/pypi
  settings:
    repository: https://my-private-pypi.com
    setupfile: setup.py
    distributions:
    - sdist
    - bdist_wheel

For testing I used the following project:

Do you have any idea what I’m doing wrong?
I would appreciate any answer that would help me.

Best regards


Edit:
There was a bug with skip_build, which got fixed.
