feat(custom generators): added '--custom-generator' parameter fixes #237

[mcaden]

usage:

--custom-generator=path/to/my/generator.jar

It handles the difference in the classpath delimiter on windows and other systems.

Should fix #237

Tested in Windows and Ubuntu.

Does it work on your machine? I tried:

npm run build
npm run cli -- --custom-generator=/path/to/extensions.jar list

I get error: unknown option '--custom-generator=...'

[mcaden]

This works:

npm run cli -- list --custom-generator=/path/to/extensions.jar

The difference is simply that list is before the --custom-generator

I also tested using npm link in the dist/apps/generator-cli directory and used it on an actual project with a real custom generator. Worked beautifully.

yarn openapi-generator-cli generate -i swagger.json -g my-generator -o out --additional-properties=supportsES6=true,withInterfaces=true --custom-generator=path/to/my-generator.jar

[SardarNL]

Indeed, it works!

I managed to do the same by simply cloning this repo and building our own cli wrapper. But the official solution is way better.

@kay-schecker Please let me know if there's anything else I need to do in order to make this eligible for merge.

Hi, please fix the linting errors: https://github.com/OpenAPITools/openapi-generator-cli/pull/335/files

[mcaden]

@kay-schecker Ah, fixed. I'm too used to that being a part of the build/commit process and didn't run lint separately.
