scalastyle-sbt-plugin 0.4.0 is messing up other plugins classpath

[sslavic]

I'm trying to use scrooge-sbt-plugin (3.12.3, still not released) and scalastyle-sbt-plugin (0.4.0) in same project. As soon as scalastyle-sbt-plugin is just added to plugins.sbt, build starts crashing, scrooge-sbt-plugin execution fails with:

Yes, we use version 3.2.0 of scopt and they use 2.1.0. We upgraded as part of 0.4.0. I'll have to have a think about the best way to sort this out. Ping me in a week or so if I haven't responded.

[sslavic]

Sounds like design issue in sbt itself, if all plugins share classpath, and thus cannot use different versions of a dependency.

[matthewfarwell]

I've removed the dependency on scopt, see commit https://github.com/scalastyle/scalastyle/commit/cecc7091f025b5ba977a718406f3f2dd5c2c4b49 Can you check if the latest build of the sbt plugin and see if you still have the problem. Thanks.

When the next public release (0.5.0) will be available?

[matthewfarwell]

This should have been fixed by 0.5.0. Closing this issue
