Build scalatest-eclipse-plugin for Scala-IDE 4.0.0 RC1

I upgraded Scala-IDE in Eclipse Luna to 4.0.0 RC1, but didn't find Scalatest plugin. It is inconvenient and time consuming to run "mvn test" every time I change the test. I decided to build Scalatest plugin by myself. It turns out pretty easy, here is how:

• Clone from github: git clone https://github.com/scalatest/scalatest-eclipse-plugin.git
• Use branch kepler-nightly-2.11: git checkout -b nightly-2.11 kepler-nightly-2.11
• Change luna profile in scalatest-eclipse-plugin/pom.xml: replace "ecosystem/next" with "sdk".

      
        scala-ide-4.0-2_11-luna
        
          2.11.2
          2_11
          2.11
          v-4
          ${repo.scala-ide.root}/sdk/lithium/e44/scala211/dev/site/
        
      
  

• Build: mvn clean package
• Install in eclipse, use "file:/${path}/scalatest-eclipse-plugin/org.scala-ide.sdt.scalatest.update-site/target/site/" in "Install new software ..."
