Can't run ./bin/scala-petstore.sh as instructed at README

[ngocdaothanh]

I have Java 1.7 and Scala 2.11.1:

java -version
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b12)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

scala -version
Scala code runner version 2.11.1 -- Copyright 2002-2013, LAMP/EPFL

I clone swagger-codegen and run ./sbt assembly. It says:

./bin/scala-petstore.sh
Please set scalaVersion := "2.11.1" in build.sbt and run ./sbt assembly

I set scalaVersion to 2.11.1 in build.sbt and run ./sbt assembly again. This time there will be error:

Suggestions:

• Why not include Scala runtime when doing the "assembly", so that you only need Java to run?
• Prerequisites at README list many things, including Scala. Why the prerequisite is not only Java? For example, if there's technical difficulties, you can preinclude SBT and Maven .jar files in swagger-codegen.

[fehguy]

you need either scala 2.9.1 or 2.10.0

[ngocdaothanh]

Just commented at #208.

[ngocdaothanh]

you need either scala 2.9.1 or 2.10.0

Why not preinclude a Scala runtime into swagger-codegen? Also, why not release a runable version of swagger-codegen so that users of swagger-codegen can run it right away without having to compile and assemble anything?

Actually it doesn't work for Scala 2.9.1 either:

Propose fix for this PR #303

[webron]

#303 is merged, and the scala version is no longer really version.
