Open questions

• Document in CONTRIBUTING.md
• Can Maven reload Jenkins automatically once bundled files change? Answer
  • I can use nodemon to re-run the Maven process whenever the bundled files change, but Maven takes too long to fully initialize Jenkins, I'm not sure it's worth it.

@stuartrowe, @timja, @lewisbirks, what do you think?

[timja]

Looks fine (untested), definitely don't want maven to re-run on changes. It will live reload anyway for frontend changes like jelly, and some Java changes are hotswappable (compile again without restarting), like changing method bodies

By the way, there must be something wrong in this plugin's Jenkins setup. When pressing Enter to reload, it just throws a bunch of crashes and Jenkins never comes back.

Looks good to me, I don't use VS Code but they look right, one minor thing but I'm happy regardless

Yeah, I've never seen that work in this plugin (no experience with others to compare it to)

I've never seen it work in any plugin, you don't really want it running in an interactive terminal as its easy for that to happen, I run it intellij where it doesn't trigger.

[lewisbirks]

I'll play around with IntelliJ and see if I can create similar configurations for running (in a separate PR)

[lewisbirks]

should we include a maven wrapper 🤔

not one for this PR probably but something to think about @timja

[felipecrs]

I have no strong opinion about it.

[felipecrs]

Alright, I have no further changes for this PR. It can be merged whenever you guys feel like.
