我正在尝试构建ApacheSpark2.1.0源代码，但是下面的错误让我很困惑。。。
hadoop2.8.0已经安装并正在运行scala2.12.1是在执行spark安装之前安装的（它似乎自动安装scala2.11.8？！？）
我的产品线是：

build/mvn -Pyarn -Phadoop-2.7 -Dhadoop.version=2.7.0 -DskipTests clean package

有人知道我为什么会得到：

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（看看这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，其中也显示了内容：

https://repo1.maven.org/maven2

希望聪明人知道怎么解决这个问题。。。
