在此之前,我遇到了通常的错误,它要求文件读/写访问.我通过chmod给了它所有权限,并手动更改了Windows上文件属性的权限设置.

wiki链接将我发送到一个页面,该页面基本上说明了插件的问题.不幸的是,没有任何东西可以指示如何解决问题.

我在Windows 7x64上,尝试使用src构建hadoop 2.5.0并使用最新版本的maven 3.2.3和jdk 1.8.0_20

Answer 1

在构建源代码时我遇到了类似的问题.而不是使用以下命令进行编译:

mvn package -Pdist,native -DskipTests=true -Dtar

我用了:

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

试试吧!
