I installed Scala 2.8 and NetBeans 6.9 on Fedora 14 (64-bit) by using repository versions (yum install scala netbeans). Then I downloaded Scala 2.8 plugin for Nb6.9 from source-forge. I installed it successfully by using Tools --> Plug-ins menus from NetBeans.

But now problem. When I start Scala project and try to compile little "helloworld" example (in order to see if compiler works), I get this:

/home/user/NetBeansProjects/ScalaApplication1/nbproject/build-impl.xml:42: You must set SCALA_HOME or environment property and append "-J-Dscala.home=scalahomepath" property to the end of "netbeans_default_options" in NetBeansInstallationPath/etc/netbeans.conf to point to Scala installation directory. BUILD FAILED (total time: 0 seconds)

I also noticed that Tools-->Scala Platforms show this http://i56.tinypic.com/110x72x.png

So probably that is part of the problem, too.

I searched for an answer prior asking here, but all tutorials seem to be outdated or dealing with completely another issue.

Do what Netbeans tells you to do. This solves the problem. :-)

  • Edit your .profile/.bashrc/.zshrc/... (whatever you use/prefer) and add an enviroment variable pointing to the directory with Scala in it.

  • Edit your netbeans.conf and add "-J-Dscala.home=scalahomepath" to the end. (Be sure to replace "scalahomepath" with the actual path.

    That's the thing, I don't know where is scala installed. It has files in /usr/share/scala/lib , /usr/bin and maybe few other places. Also, if I set Scala Platfrom (from picture) to /usr/share/scala/lib, it says it isn't valid scala directory. – user499981 Nov 07 '10 at 19:02
