Java spark中的maven依赖项向我显示了什么缺少的工件错误？

我想从Maven Central安装Spark，并包含以下依赖项：

<dependency>
  <groupId>org.apache.spark</groupId>
  <artifactId>spark-core_2.10</artifactId>
  <version>1.0.2</version>
</dependency>

如果您在代理之后，可能必须在settings.xml中指定代理。从错误消息来看，您的maven实例似乎无法连接到maven central。 有关设置代理的信息，请参见：

请，请将这一错误切碎为一个代表性错误，并在发布时将其格式设置得更好。我也遇到了这个错误，非常混乱。在我的例子中，从（可能部分损坏的）本地存储库中删除受影响的工件“工作”。。。在我的例子中，FUSE挂载（它是NTFS分区）是混乱的，所以我挂载并重新挂载了分区。
