Customising build.sub_commands directly from distutils has been deprecated and is about to be removed

[abravalheri]

The following feature in setuptools has been deprecated for almost 2 years and is about to be removed:

https://github.com/pypa/setuptools/blob/1ed759173983656734c3606e9c97a348895e5e0c/setuptools/command/build.py#L13-L27

It might be a good idea to import build directly from setuptools for the following code:

bpython/setup.py

Lines 131 to 139 in ca13bf5

	build.sub_commands.insert(0, ("compile_catalog", None))
	cmdclass["compile_catalog"] = babel.compile_catalog
	cmdclass["extract_messages"] = babel.extract_messages
	cmdclass["update_catalog"] = babel.update_catalog
	cmdclass["init_catalog"] = babel.init_catalog
	if using_sphinx:
	build.sub_commands.insert(0, ("build_sphinx_man", None))

(build is available directly from setuptools, starting on version v62.4.0)

Maybe they could stop changing everything all the time.

Maybe they could stop changing everything all the time.

To minimise the impacts of the changes in setuptools, one possibility is to cap the version of setuptools in pyproject.toml... This way the project will not be affected.

I am afraid this is only a temporary solution until distributions move to newer setuptools versions.
