如何構建使用Scala（2.9.1.RC3）和PDE（Eclipse Helios）的OSGi包。我正在使用Scala IDE（2.0.0-beta）構建項目並將其轉換爲PDE項目。 我的MANIFEST.MF是這樣的：使用Eclipse PDE和Scala IDE構建OSGi模塊和Scala
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
項目構建沒有錯誤，但是當開始出現此異常的束（使用Apache 3.2.2菲利克斯）：

和代碼：
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!");
}
}
該過程出了什麼問題？如何正確映射類Activator？
在此先感謝
您的激活器類是否實現了java接口BundleActivator？所有類型都是由包中的激活器類引用的，還是導入了包中的？ –
@ bj-hargrave是的。我也會發布代碼。 – adelarsq
您的包似乎並未導入Scala標準庫包。不幸的是，我不知道這會是什麼，但可能至少需要'scala'包。看起來你正在使用scala集合，所以你需要導入'scala.collection'，並且你可能還需要'scala.runtime'。 –
