deploy scalatra app on heroku error plugin not found

Question

I followed the guide of deploying a Scalatra app on Heroku [lien] http://www.scalatra.org/guides/deployment/heroku.html#toc_177 and I get the following error:

  > [error] (*:update) sbt.ResolveException: unresolved dependency: >com.typesafe.startscript#xsbt-start-script-plugin;0.5.3: not found 

My version of SBT is 0.13.0..

For information I'm debutante with scalatra and sbt,Please can you help me..

Answer 1

As you already mentioned your sbt version is 0.13.0 so:

on https://github.com/sbt/sbt-start-script

there are instructions for 0.13.0 version. So we need to:

1. Use com.typesafe.sbt.SbtStartScript.startScriptForClassesSettings: _* instead of com.typesafe.startscript.StartScriptPlugin.startScriptForClassesSettings: _* in build.scala and
2. In project/plugins.sbt we need to add start script plugin like addSbtPlugin("com.typesafe.sbt" % "sbt-start-script" % "0.10.0") instead of ddSbtPlugin("com.typesafe.startscript" % "xsbt-start-script-plugin" % "0.5.3")

And as a bonus: don’t forget to change servlet name in src/main/scala/JettyLauncher.scala to one you have e.g. com.blog.BlogServlet instead of one in tutorial com.example.app.MyScalatraServlet
