Añadiendo .jar's a classpath (Scala)
Así que he estado tratando de trabajar con elrecoger la señal marco y he descargado el.jar Archivos y lo extrajo en una carpeta. Actualmente la estructura de carpetas se ve como:
<code>LICENSE.txt PageRank.scala core-1.1.1-sources.jar dependencies/ javaapi-1.1.1-sources.jar NOTICE.txt README.txt core-1.1.1.jar javaapi-1.1.1-javadoc.jar javaapi-1.1.1.jar </code>
DóndePageRank.scala Es el código de prueba de Scala que proporcionan, que es:
<code>import com.signalcollect._
object PageRank extends App {
val graph = GraphBuilder.build
graph.addVertex(new PageRankVertex(id=1))
graph.addVertex(new PageRankVertex(id=2))
graph.addEdge(new PageRankEdge(sourceId=1, targetId=2))
graph.addEdge(new PageRankEdge(sourceId=2, targetId=1))
graph.execute
graph.foreachVertex(println(_))
graph.shutdown
}
class PageRankVertex(id: Any, dampingFactor: Double=0.85)
extends DataGraphVertex(id=id, state=1-dampingFactor) {
type Signal = Double
def collect(oldState: Double, mostRecentSignals: Iterable[Double]): Double = {
1 - dampingFactor + dampingFactor * mostRecentSignals.sum
}
}
class PageRankEdge(sourceId: Any, targetId: Any)
extends DefaultEdge(sourceId, targetId) {
type SourceVertex = PageRankVertex
def signal(sourceVertex: PageRankVertex) = {
sourceVertex.state * weight / sourceVertex.sumOfOutWeights
}
}
</code>Soy un novato en lo que se refiere a JVM / Java / Scala, y este fue mi intento de agregar el.jar's al classpath para compilarPageRank.scala:
<code>$ scalac -classpath *.jar dependencies/*.jar PageRank.scala error: IO error while decoding core-1.1.1.jar with UTF-8 Please try specifying another one using the -encoding option error: IO error while decoding javaapi-1.1.1-javadoc.jar with UTF-8 Please try specifying another one using the -encoding option error: IO error while decoding javaapi-1.1.1-sources.jar with UTF-8 Please try specifying another one using the -encoding option error: IO error while decoding javaapi-1.1.1.jar with UTF-8 Please try specifying another one using the -encoding option error: IO error while decoding dependencies/je-3.2.76.jar with UTF-8 Please try specifying another one using the -encoding option error: IO error while decoding dependencies/scala-library-2.9.1.jar with UTF-8 Please try specifying another one using the -encoding option 6 errors found </code>
No puedo entender qué está mal ... ¿qué está pasando? ¡Gracias! Saludos, -kstruct
