标签：lib tor 出现 scala 干货 lam cee 2.0 exec
不多说，直接上干货！
http://mvnrepository.com/
这里，怎么创建，见
这里， 我重点说下spark项目，因为，对于hadoop这样的，我已经写了大量博客了。
比如，我目前用得较多的spark-mllib。
这里spark-mllib_2.10 就是你的scala版本是2.10.X系列。比如我一般是使用scala-2.10.4。
这里spark-mllib_2.11 就是你的scala版本是2.11.X系列。
同时，大家要养成规范，http://mvnrepository.com里是示例如下
<!-- https://mvnrepository.com/artifact/org.apache.spark/spark-mllib_2.10 -->
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-mllib_2.10</artifactId>
<version>2.2.0</version>
<scope>provided</scope>
</dependency>
但是呢，我不建议这样。反而是把版本抽取出来，
以下是我的maven构建出来的spark项目的pom.xml，大家可以作为参考下。当然这不是最规范的。
