Description

I created a plugin to automatically format Java source files with import order rules.
I ran and tested it on Accumulo and it worked well, aside from a few malformed files.

(NOTE: each group is sorted within its section)

I tested using Eclipse default import order rules, which are:

static *

java.*

javax.*

org.*

com.*

* - everything else

These are a bit unnecessary, I think. A saner and more useful ordering might be:

static *

org.apache.accumulo.*

java.*

javax.*

* - everything else

Alternatively, I do like the simplicity of:

static *
(with or without blank line?)
* - everything else

The plugin can handle any of these, so we just need to pick what we like.
