Re: Getting NoSuchMethodError when using Actor

I did some more research and tests.
It looks like this is caused by different compiler options.

I tried running the same simple source (see below) with the same defined classpath, one compiled with Idea and the other compiled using Gradle's Scala plugin.
Both use the same version of the Scala compiler.
The one compiled by Idea works and the other not.
Now the only thing that I think might be different are the compiler options.
I don't know which options Gradle uses and which Idea but I'll investigate further.

Manfred

object SStarter {
def main(args: Array[String]): Unit = {
println("Hello World from main!")
new MyActor().start
}
}

class MyActor extends Actor {
def act: Unit = {
println("Hello world from act")
}
}

Best thing is to synchronize scala-compiler.jar and scala-library.jar between command level and IDE what works best for me is I rely on maven scala plugin to pull required jar's into local maven and then point IDE to very same local maven repository (.m2/repository)
Hope this helps:)

Well, yeah :)
But I don't want to start Idea just to compile my stuff. :)

Replying to myself.

Overriding the Gradle compileScala task and doing it with Ant works.
Now I guess I have to go to the Gradle guys. :|

i've been programming for about 15 years now and i NEVER ran a compiler
by myself even once except when i've been force to in school:
teacher: "javac"
me: "why?"
teacher: "so that you learn"
me: "you also want me to focus on breathing while living, yes?"

Master: Cut this plank to 58 cm in length.
Apprentice: Why?
Master: Because we need a 58-cm plank, you dumb-ass!
