Setup development evironment for SCALA 2.9 and Netbeans 7.0 in linux (Ubuntu 11.04)

• Go to https://www.scala-lang.org/downloads and get the tgz package for Unix, MacOS X, Cygwin. The current latest stable release is scala 2.9.1
• Suppose that the downloaded package is in your home directory, open the terminal and type these lines:

  $> tar -xvf scala-2.9.1.final.tgz
  $> sudo mv scala-2.9.1.final/ /usr/share/scala/

  Remember to replace the 2.9.1 by your scala version

• The next thing to do is register the SCALA_HOME and PATH environment variable. To do this, open the ~/.profile file and add these new lines to the end of the file

  export SCALA_HOME=/usr/share/scala
  export PATH=$PATH:$SCALA_HOME/bin

• Log out and the log in again. Test you installation by typing this command in the terminal. If the terminal change to scala> then you have successfully installed scala.

  $> scala

I use the nbscala plugin to develop scala projects. To use this plugin in Netbeans 6, you can use the Netbeans plugin management in Tools > Plugins. For Netbeans 7.0, you can do as below:

• Go to https://github.com/dcaoyuan/nbscala to get the latest version of this plugin source code or https://sourceforge.net/projects/erlybird/files/nb-scala/ to get the built package.
• Extract your downloaded package to the local storage
• In Netbeans, go to Tools > Plugins choose the Downloaded tab and click Add plugins … button
• Select your new nbm files and click OK, continue to follow what the wizard says.
• Restart the IDE

Now, you can create your first scala project in Netbeans. Just create a new project and keep the default settings, you will have a Hellow world scala application. Click Run. If the the string Hello world is printed in the output then your Netbeans is ready.
