This is an old issue: http://www.assembla.com/spaces/scala-ide/tickets/1919?utf8=%E2%9C%93&... However, it hasn't been fixed yet.
Here http://www.assembla.com/wiki/show/scala-ide/Eclipse_Plugin_Developmen... I found something useful for deployment but it seems a little awkward
Could anyone point me out some practical solution? Are the Scala IDE developers going to fix this issue (soon)?
