maven - 无法使用 Java8 构建 Hadoop 2.4.1

Question

这个问题很简单。我正在尝试使用以下命令在 Windows 上编译 Hadoop2.4.1:

mvn clean package -Pdist,native-win -DskipTests -Dtar

使用 JAVA_HOME=C:\Program Files\Java\jdk1.7.0_51，它工作正常。

使用 JAVA_HOME=C:\Program Files\Java\jdk1.8.0_05 时，它不会并失败，并给出以下错误:

如前所述，除了 JAVA_HOME 外，我没有做任何更改。错误消息似乎表明错误与代理相关，但我不知道为什么。

在这两种情况下，我都有

C:\hadoop-src>javac -version
javac 1.8.0_05

和

C:\hadoop-src>java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

你们能知道发生了什么事吗？

替代 Stuarts 的建议(我很难找到放置附加参数的位置):为了完全跳过 javadoc 生成，只需运行

mvn clean package -Pdist,native-win -DskipTests -Dtar -Dmaven.javadoc.skip=true
