There was a course, Software Development Environments, on the CS degree programme I studied that taught a lot of these things. I was very grateful for it.
I'm a compsci teacher in the school I finished my pre-uni education in. When I was applying for teacher training the school asked to have me as an intern. 6 months later they hired me on a permanent basis. So getting the intern placement there was largely because they knew me from when I was a student then that gave me the chance to show them what I can do.
I fondly remember being introduced to this library as part of the first project I worked on at my first development job. I was lucky there it was the right challenge at the right time.
