Document how to use the checkstyle plugin provided by JOSM in Eclipse

[GerdP]

See #16938#comment3 and #16938#comment7

I tried to put the file \josm\core\tools\checkstyle\checkstyle-all.jar into dropins\plugins as well as
plugins,each time followed by a start with eclipse -clean. I saw no effect.

Maybe I have to uninstall the "normal" checkstyle plugin?

Thanks for the reminder. I need to document this and without a ticket, I forgot :)

I just noticed that you fixed some of "my" formatting warnings. Maybe you can give me a short hint where I might find a solution?

[Don-vip]

The warnings I fixed recently were related to:

• we use only spaces characters, no tabs
• the shortcuts are parsed by a script to generate DevelopersGuide/ShortcutsList and thus must remain on a single line

Oops, seems I changed your reply instead of quoting it. Sorry for that.
I looked at DevelopersGuide/ShortcutsList and it still shows a parsing error. I also found several sources where the registerShortcut statement spans multiple lines and the list shows them.
BTW: I did not find the script in the svn repo.

Hmm, again and again I find that my Eclipse Editor adds Tabs instead of blanks when I change plugin sources. Since nobody seems to know how to make the customized checkstyle plugin work in Eclipse maybe someone can tells me how I can configure the Editor correctly for all plugins?
I have another project which prefers tabs and that really messes up my work flow.
