java - 编译 Hadoop native - 在 Maven 插件中发现错误

Question

我正在尝试编译 Hadoop，但在 ant 插件中出现 Maven 错误。我从未使用过 Maven 或 ant，错误似乎没有给出任何错误所在的指示。错误输出在文章末尾。

我在 pom 文件中搜索了 maven-antrun-plugin(有 54 个 pom.xml 文件带有该字符串)。该错误表明它位于 hadoop-common 下的文件中，但在该文件中出现了多个 maven-antrun-plugin。我不知道哪一个是问题所在，Maven 错误掩盖了任何命令失败给出的实际错误消息。

我如何:

1. 准确找出导致错误的行
2. 获取实际的错误输出而不是Maven的无用错误

这是错误:

确保你已经在你的机器上安装了 cmake。如果您使用的是 Ubuntu，则可以使用以下命令安装 cmake

sudo apt-get install cmake

安装完成后，尝试编译...
