Scala In Uni Labs

Sorting out environment variables

• To get Scala and Netbeans working in the University labs, first add these lines to your ~/.bashrc file:

export SCALA_HOME=/opt/scala-2.8.1.final
export PATH=$PATH:/opt/scala-2.8.1.final/bin
alias netbeans='netbeans J-Dscala.home=/opt/scala-2.8.1.final/
 

• Reload your ~/.bashrc file in the usual way:

$ source ~/.bashrc
 

• From now on you MUST start Netbeans from the command line, like this:

$ netbeans
 

not from the Applications menu. Also, you may see an error message about the Scala directory, just ignore this.

Installing the plugins

• Get the Scala plugins from here: http://sourceforge.net/projects/erlybird/files/nb-scala/6.9v1.1.0/
• Save them somewhere and unzip them (right click on the .zip file and select Extract here).
• Open Netbeans from the command line:

$ netbeans
 

Ignore any error messages about the Scala directories.

• Go to Tools -> Plugins on the menu.
• Select the Downloaded tab.
• Click on the Add plugins button.
• In the dialog box that opens up, go to the directory where you unzipped the Scala plugins. Select ALL the files in the directory and press OK.
• Say yes to all the questions and install.
• Close Netbeans and open it up again (from the command line!).
