Eclipse PDE와 Scala IDE를 사용하여 Scala로 OSGi 모듈 빌드하기

Question

PDE (Eclipse Helios)에서 Scala (2.9.1.RC3)를 사용하는 OSGi 번들을 빌드하는 방법. Scala IDE (2.0.0-beta)를 사용하여 프로젝트를 빌드하고이를 PDE 프로젝트로 변환합니다.

Manifest-Version: 1.0 
Bundle-ManifestVersion: 2 
Bundle-Name: ScalaTest1 
Bundle-SymbolicName: ScalaTest1 
Bundle-Version: 1.0.0.qualifier 
Bundle-Activator: scalatest1.Activator 
Import-Package: org.osgi.framework;version="1.3.0" 
Bundle-RequiredExecutionEnvironment: JavaSE-1.6 

오류없이 프로젝트 빌드 만이 예외가 나타납니다 번들을 시작할 때 (아파치 펠릭스 3.2.2 사용) : 내 MANIFEST.MF는 같다

그리고 코드를 :

package scalatest1 

import org.osgi.framework._ 

class Activator extends BundleActivator { 
    def start(context: BundleContext) { 
    println("Hello, World!"); 

    val bundleNames = context.getBundles() 
     .map(b => b.getSymbolicName()) 
     .filter(b => b != context.getBundle()); 
    println("Installed bundles: " + bundleNames.mkString(", ")); 
    } 

    def stop(context: BundleContext) { 
    println("Goodbye, World!"); 
    } 
} 

프로세스에 어떤 문제가 있습니까? Activator 클래스를 올바르게 매핑하는 방법은 무엇입니까?

미리 감사드립니다.

Answer 1

나는 어리석은 문제를 발견했습니다. "작업 공간에서 컴파일 된 클래스 파일 사용"필드를 내보낼 때 표시가 해제되었습니다. 작동하지만 .scala 파일이 내 보낸 .jar 파일에있는 또 다른 문제점이 있습니다.

Answer 2

.scala 개의 파일을 JAR로 내보내지 않고이 작업을 수행하는 방법은 http://www.michel-kraemer.com/scala-projects-with-eclipse-pde-build-2을 참조하십시오.
