spotless-cli version (if relevant)

No response

Describe the feature

i would like to see support for eclipse formatter because google formatter:

a) messes up /// and // formatting used by jbang :)
b) can't be configured with something I can use across all IDE's
c) its what I use in jbang so coupled with #10 could make easy formatting without relying on build specific limits.

:)

Motivation and use case

I use eclipse formatter, not google-java-format
