java.lang.NoClassDefFoundError：org / apache / spark / streaming / kafka / KafkaUtils

我正在使用以下pom.xml来构建我的项目 . 当我用spark提交生成的jar时，它会出现以下错误 .

java.lang.NoClassDefFoundError：org / apache / spark / streaming / kafka / KafkaUtils

但是，如果我包含--packages“org.apache.spark：spark-streaming-kafka-0-8-assembly_2.11：2.0.2”选项，它会像往常一样运行 . 当我的依赖项作为pom.xml的一部分包含在内时，我不明白为什么必须提供此选项 .
