我正在運行一個scala程序，在下面。我正在使用maven進行構建，並且我已經正確設置了依賴關係，並且maven安裝成功。但是當運行jar文件時，我得到java.lang.NoClassDefFoundError。找不到類的錯誤 - scala
計劃：
package RasterDataIngest.RasterDataIngestIntoHadoop
import geotrellis.spark._
import geotrellis.spark.ingest._
import geotrellis.spark.io.hadoop._
import geotrellis.spark.io.index._
import geotrellis.spark.tiling._

import com.quantifind.sumac.ArgMain
import com.quantifind.sumac.validation.Required
class HadoopIngestArgs extends IngestArgs {
@Required var catalog: String = _
def catalogPath = new Path(catalog)
}
object HadoopIngest extends ArgMain[HadoopIngestArgs] with Logging {
def main(args: HadoopIngestArgs): Unit = {
System.setProperty("com.sun.media.jai.disableMediaLib", "true")
implicit val sparkContext = SparkUtils.createSparkContext("Ingest")
val conf = sparkContext.hadoopConfiguration
conf.set("io.map.index.interval", "1")
val catalog = HadoopRasterCatalog(args.catalogPath)
val source = sparkContext.hadoopGeoTiffRDD(args.inPath)
val layoutScheme = ZoomedLayoutScheme()
Ingest[ProjectedExtent, SpatialKey](source, args.destCrs, layoutScheme, args.pyramid){ (rdd, level) =>
catalog
.writer[SpatialKey](RowMajorKeyIndexMethod, args.clobber)
.write(LayerId(args.layerName, level.zoom), rdd)
}
}
}

請讓我知道我走錯了.. 由於事先在哪裏！
