ROS2 Following basic service/client tutorial, executables doesn't seems to install

edit

For a bit of context, I am using Ubuntu 20.04 with ROS2 Foxy. I followed this tutorial : https://docs.ros.org/en/foxy/Tutorial...

To recap everything I have done :

- open new terminal :
source /opt/ros/foxy/setup.bash
mkdir -p dev_ws/src
cd dev_ws/src 
ros2 pkg create --build-type ament_python py_srvcli --dependencies rclpy example_interfaces

python py_srvcli --dependencies rclpy example_interfaces
going to create a new package
package name: py_srvcli
destination directory: /home/user/Stage_ros/test/dev_ws/src
package format: 3
version: 0.0.0
description: TODO: Package description
maintainer: ['user <bastian.muratory@gmail.com>']
licenses: ['TODO: License declaration']
build type: ament_python
dependencies: ['rclpy', 'example_interfaces']
creating folder ./py_srvcli
creating ./py_srvcli/package.xml
creating source folder
creating folder ./py_srvcli/py_srvcli
creating ./py_srvcli/setup.py
creating ./py_srvcli/setup.cfg
creating folder ./py_srvcli/resource
creating ./py_srvcli/resource/py_srvcli
creating ./py_srvcli/py_srvcli/__init__.py
creating folder ./py_srvcli/test
creating ./py_srvcli/test/test_copyright.py
creating ./py_srvcli/test/test_flake8.py
creating ./py_srvcli/test/test_pep257.py

cd .. (now i am in /dev_ws) :

rosdep install -i --from-path src --rosdistro foxy -y

#All required rosdeps installed successfully

colcon build --packages-select py_srvcli

Starting >>> py_srvcli
--- stderr: py_srvcli                   
listing git files failed - pretending there aren't any
---
Finished <<< py_srvcli [2.44s]

Summary: 1 package finished [2.89s]
  1 package had stderr output: py_srvcli

My question is why is there an error with git meanwile I never used git anywhere in this tutorial ?

Furthemore, i then sourced the install directory :

. install/setup.bash

and ran :

ros2 run py_srvcli service

which then told me no executables found ... Am I missing something ?

EDIT : I have already added the entry points, here is my setup.py as it might help

from setuptools import setup

package_name = 'py_srvcli'

setup(
    name=package_name,
    version='0.0.0',
    packages=[package_name],
    data_files=[
        ('share/ament_index/resource_index/packages',
            ['resource/' + package_name]),
        ('share/' + package_name, ['package.xml']),
    ],
    install_requires=['setuptools'],
    zip_safe=True,
    maintainer='user',
    maintainer_email='bastian.muratory@gmail.com',
    description='TODO: Package description',
    license='TODO: License declaration',
    tests_require=['pytest'],
    entry_points={
        'console_scripts': [
            'service = py_srvcli.service_member_function:main',
            'client = py_srvcli.client_member_function:main',
        ],
    },
)

and finally, here is the tree from the dev_ws
