[All] Build commands for all supported langs

Description

I'm attempting to improve the user experience with building the packages for all langs that swagger-codegen supports. At the moment, each user of the generated code would be left with the task to figure out how to build the package, multiply this with the number of swagger-codegen users, this becomes a repeated effort that can be simplified.

I have a node.js CLI tool that contains the commands (currently only on few languages) needed to build the packages, e.g. https://github.com/cliffano/swaggy-c/blob/master/conf/tasks.yml#L496

In order to complete the commands list, I need to find out the commands to perform the following tasks for each of the generated langs?

• resolve dependencies
• run unit tests
• build the package
• install the package locally
• generate code documentation
• publish the package to an artifact repository

Is there a documentation or build script that lists the commands? If not, should I be asking the maintainers of each template/lang?

Also, what do you think about adding a Makefile that contains the targets to perform the above tasks? for each language. At least that could be self contained within the generated code.
I understand that a Makefile might not be OS-neutral enough, or perhaps it's not necessary within a given language. Please let me know what you think.

Start with the existing commands in conf/tasks.yml and compare them with the generated language templates supported by swagger-codegen. Determine whether each language has documented commands for dependency resolution, tests, builds, local installation, documentation, and publishing. Done means a decided, maintainable approach for covering those tasks, including whether a generated Makefile is appropriate.
