Configuration option to use other code formatters

[tfield]

Hi. First post.

I am interested in exploring the possibility of using a different formatter than the default Eclipse formatter with this tool.

There are a few other formatters that are popular that warrant consideration (google-java-formatter and prettier-java for starters). Initially, my interest is with google-java-formatter but the capability is just as important.

A few questions for those in the know:

1. Is this philosophically a non-starter?
2. Has there been consideration about this in the past? I would love to follow up on the discussion. I saw a draft PR that has been in limbo for a few years, but beyond that, anything?
3. What would be involved? At first glance, it seems that we'd want to either configure a different FormatterHandler (and options) or educate the FormatterHandler to delegate to a formatter of choice. Perhaps either create a plugin (which gets messy) or else expose an interface that contributors can extend (i.e. internal plugin) as part of the standard distribution?

I'm completely new to this project, so I do face a steep learning curve, but would be willing to contribute. My daily driver IDE is IntelliJ but I teach students using vscode and have been experimenting with zed, both of which would benefit from this proposed extension.

Thanks - looking forward to learning more.
