Proposal: source-fixes-maven-plugin

[Jochen Wiedmann]

Hi,

what is our stance with regard to new plugins? Because, I'd like to propose one:

The source-fixes-maven-plugin (Suggestions for a better name quite welcome.)
is kind of companion to the checkstyle-maven-plugin.
If there are issues, that the latter detects, and that can be fixed
automatically, then
the former will do just that. Examples:

- Replace leading spaces with tabs, or vice versa.
- Replace CRLF with LF, or vice versa.
- Remove trailing blanks.

Background: Working on commons-lang, I notice that I spend more time
fixing Checkstyle issues like the above than doing the actual work.

Jochen

Hi Jochen,

https://github.com/revelc/formatter-maven-plugin seems to support
already the things you've listed.

Cheers,

Hey,

I think the checkstyle team is working on sth similar.

The plugins "spotless" and "formatter" have limitations themselves. I was not able to get them working properly in every edge case (i.e. additional file types like groovy, xml, etc.).

if you are using an .editorconfig, then the editorconfig-maven-plugin's
format goal [1] should be able to accomplish this, at least for the
three properties you've listed above [2]. Hope this helps.

Best wishes,

Andreas
