----------------------------------------
Summary: Custom library setup.py fails airflow
Key: AIRFLOW-5466
URL: https://issues.apache.org/jira/browse/AIRFLOW-5466
Project: Apache Airflow
Issue Type: Bug
Components: cli
Affects Versions: 1.10.5, 1.10.4, 1.10.3
Reporter: Yegor Andreenko
I have created custom library to manage dags description. It's common used
functions like get configuration, slack_hook definition, etc.
For that library I created `setup.py` file inside my project(seems legit). This
project is supposed to be used like
```
<project>/
dags/
setup.py
dags_1.py
dags_N.py
config/.....
__init__.py
test/
```
And we usually deploy dags folder to airflow.
Airflow will crash `initdb`, `scheduler`, `webserver` commands if it encounters
`setup.py` file in `dags` folder with an error message:
```
usage: airflow [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: airflow --help [cmd1 cmd2 ...]
or: airflow --help-commands
or: airflow cmd --help
error: invalid command 'webserver'
```
Expected behaviour:
- airflow shouldn't fail on `setup.py` file
- or have a more clear message what went wrong
