星火SBT编译问题

在我的编辑，即使我按在src /主/资源文件夹Twitter的jar文件，但SBT编译没有接他们，并编译和打包没有错误，但在运行时给了我错误的“类未找到twitterUtils”星火SBT编译问题

我的问题是，为什么SBT不包括在编译从资源文件夹中的jar文件？

人们告诉我要做所有这些复杂的步骤来获取Git实用程序，然后做一个sbt程序集，我做了，但因为iam后面的代理Git不工作，即使所有的http_proxy设置。我也试过把这些twitter jar文件放在CLASSPATH中，没有运气。我坚持这个问题，所以任何帮助，高度赞赏。请参阅下面

细节我的问题是，为什么SBT不包括在编译从资源文件夹中的jar文件？

因为这不是资源文件夹是。如果要手动管理依赖关系，请输入put them into lib folder instead。但在这种情况下，您还需要对这些依赖关系的所有依赖关系，它们的依赖关系等进行相同操作。正如链接文档中所述，使用托管依赖关系通常是一个更好的主意。

嗨Alexey我没有看到链接的文档可以请你张贴链接在这里？为什么不SBT下载Twitter的依赖JAR文件，因为它在build.sbt文件相关的列表“火花流，叽叽喳喳？请查看下面的” libraryDependencies ++ = SEQ（ ‘org.apache.spark’％ “spark-core”％sparkVersion，“ ”org.apache.spark“%%”spark-streaming“ –

对不起，我发现链接没关系，但我的问题仍然存在。为什么Twitter的罐子不被下载，即使他们是在依赖关系列表？或者他们正在下载和我找不到类错误是什么东西？ –

我将我的twitter jar文件放在lib文件夹和clean-compile-package中，但仍未找到“twitterUtils”[root @ hadoop1 lib]＃pwd /root/TwitterPopularTags/lib [root @ hadoop1 lib]＃ls -ltr total 360 -rw-r - r-- 1 root root 60808 Sep 16 11:18 twitter4j-stream-4.0.4.jar -rw-R - R-- 1根根290456 09月16日11时18分twitter4j核-4.0.4.ziptwitter4j核-4.0.4.jar -rw-R - R-- 1根根14115月16 11:18 dstream-twitter_2.11-0.1.0-SNAPSHOT.jar [root @ hadoop1 lib]＃ –
