用eclipse执行kafka-stream示例，由于librocksdbjni.dll出现UnsatisfiedLinkError而失败(找不到依赖项) [英] Executing kafka-stream example with eclipse, fails with UnsatisfiedLinkError for librocksdbjni.dll (Can't find dependency)

问题描述

我正在尝试使用Eclipse IDE运行kafka-stream wordcount示例，但出现以下错误:我在pom文件中添加了0.10.1.0 kafka-client和0.10.1.0 kafka-stream作为依赖项.我还检查了依赖关系树，它使用的是rocksdbjni-4.9 jar.根据互联网上的一些阅读，此问题已在kafka的0.10.1.0版本上得到修复，但我仍在获取.有帮助吗?

I am trying to run a kafka-stream wordcount example with eclipse IDE but getting following error: I have added 0.10.1.0 kafka-client and 0.10.1.0 kafka-stream as dependency in my pom file. I have also checked the dependency tree and it's using rocksdbjni-4.9 jar. Based on some read on internet, this issue has been fixed on 0.10.1.0 version of kafka but I am still getting. Any help?
