spark mllib配置pom.xml错误 Multiple markers at this line Could not transfer artifact net.sf.opencsv:opencsv:jar:2.3 from/to central (https://repo.maven.apache.org/maven2): repo.maven.apache.org

  刚刚spark mllib,在maven repository网站http://mvnrepository.com/中查询mllib后得到相关库的最新dependence为:

<dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-mllib-local_2.11</artifactId>
        <version>2.1.0</version>

</dependency>

但是遇到错误:

Multiple markers at this line
- Failure to transfer
net.sf.opencsv:opencsv:jar:2.3
from https://repo.maven.apache.org/maven2
was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced.
Original error: Could not transfer artifact
net.sf.opencsv:opencsv:jar:2.3
from/to central (https://repo.maven.apache.org/maven2):
repo.maven.apache.org

查找后尝试过得方法有:

方案1:认为有的库没有下载完整,因此删除~/.m2/repository下所有内容——>重启eclipse——>让eclipse自动下载新的包;

  结果:不好使,没有解决掉;

方案2:(误打误撞的方法,见笑了)也认为没有下载完整,更改其他版本的mllib库为:

  <dependency> <!-- Spark dependency -->
      <groupId>org.apache.spark</groupId>
      <artifactId>spark-mllib_2.10</artifactId>
      <version>1.6.1</version>
      <scope>provided</scope>
  </dependency>
然后,eclipse自动下载库文件,等待完成(中间不要终止),然后错误消失。甚至更改为最新版本库也没有出现原来错误。

总结:

应该还是库文件不完整造成的问题,但是也还不确定,希望以后可以慢慢理解其中原理。
