Hi,

I've just commited a change to the github repo which should add luna support. I'll continue to use it over the next couple of days to see if there are any problems with it. I'll then put it on the update site.

See https://github.com/scalastyle/scalastyle-plugin/issues/18

If anyone is willing, they can build it and see if it works for them.

For info, it seems the classpath handling has changed slightly between kepler and luna.

Have fun,

Matthew Farwell.

Hi Matthias,

do you have working version of ScalaStyle on Luna? We would like to switch to Luna in our company and it'll be great to have working version of it.

Hmm, I don't know, yet what went wrong on my Windows laptop, but at my Linux box at home adapting the version restriction worked out of the box. Unfortunately it seems that more work is required to make this work with Luna, as this is what I got when attempting to open the preference page:

Matthew, I could look into this myself in the next few days if you are busy right now.
