StormCrawler maven打包报错

Question

我正在尝试设置运行 Storm Crawler 并关注 http://digitalpebble.blogspot.co.uk/2017/04/crawl-dynamic-content-with-selenium-and.html 博客 post。

StormCrawler 的资源集和配置在我的电脑上/Users/deividas/git/selenium-tutorial

在运行ning 命令 "mvn clean package" 之后弹出以下错误：

"Could not resolve dependencies for project com.digitalpebble.crawl:selenium-tutorial:jar:1.0-SNAPSHOT: Could not find artifact ring-cors:ring-cors:jar:0.1.5 in central (https://repo.maven.apache.org/maven2)"

我该如何解决这个问题？

提前致谢！

不确定为什么在您的案例中没有下载。我删除了我的本地缓存和运行下面的命令

    mvn clean package | grep cors

    Downloading: https://repo.maven.apache.org/maven2/ring-cors/ring-cors/0.1.5/ring-cors-0.1.5.pom
    Downloading: https://clojars.org/repo/ring-cors/ring-cors/0.1.5/ring-cors-0.1.5.pom
    Downloaded: https://clojars.org/repo/ring-cors/ring-cors/0.1.5/ring-cors-0.1.5.pom (4 KB at 5.0 KB/sec)
    Downloading: https://repo.maven.apache.org/maven2/ring-cors/ring-cors/0.1.5/ring-cors-0.1.5.jar
    Downloading: https://clojars.org/repo/ring-cors/ring-cors/0.1.5/ring-cors-0.1.5.jar
    Downloaded: https://clojars.org/repo/ring-cors/ring-cors/0.1.5/ring-cors-0.1.5.jar (6 KB at 24.4 KB/sec)

如您所见，它是从 clojars.org

下载的

此依赖项继承自 storm-core

 mvn dependency:tree | grep -C 20 cors

如果您查看 storm pom，您可以看到已定义 clojar 存储库。作为解决方法，您可以将存储库部分复制到项目的 pom 中。希望那时可以下载 jar。
