Question

我正在尝试在Windows上构建Hadoop-24。突然之间一切正常：

[INFO] Apache Hadoop HttpFS .............................. FAILURE [8.568s]

相关的错误是：

[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

一切似乎都表明了连接错误。但是：

其他软件包下载没有问题（通过Maven和Ant）
代理配置得很好（参见第一点）
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，我想理解为什么这不能自然地起作用。你们有人会看到原因吗？

Answer 1

这是由于代理设置。理论上，maven应该检查/.m2下的settings.xml文件，但由于某种原因，maven ant运行插件不会这样做。所以你必须在maven命令中指定它，如下面的那个

mvn package -Dhttp.proxyHost=<your proxy host> -Dhttp.proxyPort=8080

连接被maven + ant拒绝：
