我正在尝试构建 Apache Spark 2.1.0 源代码，但下面出现的这些错误令我感到困惑...
Hadoop 2.8.0 已安装并正在运行 在执行 Spark 安装之前安装了 Scala 2.12.1(这似乎会自动安装 Scala 2.11.8？!？)
我的构建线是:
build/mvn -Pyarn -Phadoop-2.7 -Dhadoop.version=2.7.0 -DskipTests clean package
有人知道我为什么得到:
user@server:/usr/local/share/spark/spark-2.1.0$ sudo /usr/local/share/spark/spark-2.1.0/build/mvn -Pyarn -Phadoop-2.7 -Dhadoop.version=2.7.0 -DskipTests clean package

我测试了手动下载(以查看是否是导致错误的原因)，下载没有问题:
https://repo1.maven.org/maven2/org/apache/apache/14/apache-14.pom
我还测试了访问下面的 URL，它也显示了内容:
https://repo1.maven.org/maven2
希望聪明的人知道如何解决这个...
最佳答案
我发现了问题所在:
我必须在目录中的 SETTINGS.XML 中配置我们的代理设置:
/usr/local/share/spark/spark-2.1.0/build/apache-maven-3.3.9/conf
编辑文件后，构建没有任何问题:)
希望这可以帮助遇到同样问题的其他人...
编辑:需要特别说明的是，仅在 bash 中具有有效的代理配置不足以使 Maven 构建成功。我能够手动从 bash 下载所有文件，但 Maven 还需要 SETTINGS.XML 文件中的代理配置...
