@nedtwigg If you don't mind, I do this all in one PR. I would appreciate if you could use this branch to provide new versions for:

• spotless-eclipse-cdt
• spotless-eclipse-groovy
• spotless-eclipse-wtp

I don't think that we need a new spotless-eclipse-jdt version. The behaviour has changed (actually some versions ago). Have a look at my comments on the UTs if you are interested.
Anyhow, don't see a need to change the code. Would propose to wait with a new versions when I (finally) finished my work on #292.

In the change logs I left a few TBDs. Will fill the blanks as soon as we have the new versions.

This PR will provide fix for #422 .

Looks great! In progress...

All three have been published to jcenter and mavencentral.

@nedtwigg Tested the new defaults with some projects, including JUnit. Since I used old code versions, nothing changed except for Groovy (see also changes in 1c44cda ).

FYI: I came across a known WTP JSON bug. Since it is already part of 3.8, I see no reason not to upgrade the default.

Released in x.24.0
