Which would be the workflow to debug with IntelliJ's IDEA ?

[Alberto Yanez]

I have managed to modify the code and have it reload by JRebel when running Jetty from SBT. However, that way the breakpoints in IDEA do not work. So I added an Embedded Jetty Object to run Jetty from withing IDEA

object JettyEmbedded {

  def main(args: Array[String]) {

    val server = new Server(9080)

    val context: WebAppContext = new WebAppContext();

    context.setServer(server)

    context.setContextPath("/");

    context.setWar("src/main/webapp")

    server.setHandler(context);

    try {

      server.start()

      server.join()

    } catch {

      case e: Exception => {

        e.printStackTrace()

        System.exit(1)

      }

    }

  }

}

Now I have 2 problems: 

• the JRebel plugin within IDEA does not reload the modified classes. 
  
• I am having problems getting the Embedded Jetty to pick some Jade Templates 
  

I am new to JRebel and Scalatra so probably there are several things that I am missing.  Please provide suggestions on how to improve my debugging workflow.

-Thanks

I found that setting IDEA for remote debugging is easier:

http://stackoverflow.com/questions/4150776/debugging-scala-code-with-simple-build-tool-sbt-and-intellij

1. Setup as instructed.
   
2. Go to command window and set JAVA_OPTS environment variable: "set JAVA_OPTS=-javaagent:/stools/jrebel/jrebel.jar %JAVA_OPTS% -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005"
3. Start sbt
4. Start Jetty: container:start
5. Set sbt to monitor sources: "~ ;copy-resources;aux-compile"

Everything is working except I get a JRebel error whenever I change the source code:

[2013-03-31 00:06:32] JRebel: Class 'org.fusesource.scalate.support.ScalaCompiler' could not be processed by org.zeroturnaround.jrebel.s...@java.net.URLClassLoader@13109a54

org.zeroturnaround.bundled.javassist.CannotCompileException: [source error] askShutdown() not found in scala.tools.nsc.Global

So far the error doesn't seem to have an impact....but if anybody knows how to fix this it would be great.

Thanks,
