There's been an API change between 6.8 and 6.9 that makes Kojo not work with Netbeans 6.9.

I haven't had a chance to dig into this (I'm expecting that I'll have to dive into the Netbeans API wormhole to figure the incompatibility out; something that I'm hoping that I can delay till the release of the next version of Netbeans, to make the effort worth it).

It couldn't clean-build kojo. Final error was

/Applications/NetBeans/NetBeans 6.9.1.app/Contents/Resources/NetBeans/harness/build.xml:168: Cannot compile against a module: /Applications/NetBeans/NetBeans 6.9.1.app/Contents/Resources/NetBeans/ide/modules/org-netbeans-modules-csl-api.jar because of dependency: org.netbeans.modules.csl.api/1 > 1.11.1.1.1.1.1
BUILD FAILED (total time: 12 seconds)

I'll try again and follow the instructions this time :-).

Works like a charm now. StupidSexyMercurial named it peterlewerin-staging and I didn't change it.

Thanks!

Well, back to polluting the clone with my own code and creating my very own troubles… :)

That's the problem.

Take a look at the installDir method in net.kogics.kojo.util.Utils. The exception is coming out of there. Maybe your source root dir is not called kojo or Kojo?

These are known rough edges in the Netbeans Scala Plugin.

Ah. I usually my own configuration first and the tool last, but the plugin is of course still being developed.

Do you still see this (if so, please provide a stacktrace)?

Yep, unfortunately.

I get several problem tasks that report missing symbols (e.g. Point, method instance() in Singleton subclasses

These are known rough edges in the Netbeans Scala Plugin.

the build succeeds and I can run Kojo, but I almost immediately get an NPE or Illegal State Exception

Do you still see this (if so, please provide a stacktrace)? Or can you run Kojo successfully now?

When I try to build Kojo I get several problem tasks that report missing symbols (e.g. Point, method instance() in Singleton subclasses). Most of these disappear if I open the source file that defines the class or symbol, but others remain. Still, the build succeeds and I can run Kojo, but I almost immediately get an NPE or Illegal State Exception.

I've made a slight change to ScalaCodeRunner.scala; in Builtins I changed the declaration of Random and added two methods:

 private val Random = new scala.util.Random import scala.math._ def random[A] (upperBound: A)(implicit n: Numeric[A]): A = { val ub = n.toDouble(upperBound) if (upperBound.isInstanceOf[Int]) (Random.nextInt(ub.toInt)).asInstanceOf[A] else if (upperBound.isInstanceOf[Float]) (Random.nextFloat * ub.toFloat).asInstanceOf[A] else (Random.nextDouble * ub).asInstanceOf[A] } def random[A] (lowerBound: A, upperBound: A)(implicit n: Numeric[A]): A = { val lb = n.toDouble(lowerBound) val ub = n.toDouble(upperBound) - lb val r = lb + random(ub) if (upperBound.isInstanceOf[Int]) r.toInt.asInstanceOf[A] else if (upperBound.isInstanceOf[Float]) r.toFloat.asInstanceOf[A] else r.asInstanceOf[A] }

If I can't get it to work I'll try reverting the change, but it doesn't seem likely that the above should be causing the problems mentioned.

Any ideas?

EDIT: I've reverted to revision 175 of KojoEnv now, and that actually made the reports about Point go away, but NB still can't find RunContext or CodeRunner unless I open core/codeRunner.scala in a window. And nothing I do makes the instance method visible, apparently. Curious.
