我正在尝试在 Windows 上构建 Hadoop-24。 突然一切正常:
[INFO] Apache Hadoop HttpFS .............................. FAILURE [8.568s]
相关错误是这样的:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7: run (dist) on project hadoop-hdfs-httpfs: An Ant BuildException has occured: java.net.ConnectException: Connection refused: connect

一切似乎都表明连接错误。然而:
- 其他包下载顺利(通过 Maven 和 Ant)
- 代理配置良好(请参阅第一点)
- 我可以通过 Firefox 下载上述文件。
现在，我通过手动下载文件并将其放在预期的位置来避免这个问题。但是，我想了解为什么这不能自然地发挥作用。大家能看出原因吗？
最佳答案
这是由于代理设置所致。理论上，maven应该检查/.m2下的settings.xml文件，但由于某种原因，maven ant run插件不会这样做。所以你必须在maven命令中指定它，如下所示
mvn package -Dhttp.proxyHost=<your proxy host> -Dhttp.proxyPort=8080
