Scalatest say this plugin is still in beta so they haven't published any final release so i had to add their plugin repo to the module, but it seems to work. Run completed in 257 milliseconds. Total number of tests run: 16 Suites: completed 3, aborted 0 Tests: succeeded 16, failed 0, ignored 0, pending 0 All tests passed. -d > > > On Fri, Jul 26, 2013 at 8:35 AM, Jake Mannix <[email protected]> > wrote: > > > I'm on your branch (dev-0.9.x-scala) but only doing a "mvn install" > inside > > of the new module - maybe I need to do it from the top level? > > > > > > On Fri, Jul 26, 2013 at 7:23 AM, Dmitriy Lyubimov <[email protected] > >wrote: > > > >> On Jul 26, 2013 12:57 AM, "Jake Mannix" <[email protected]> wrote: > >> > > >> > Woohoo!
