当我尝试运行 mvn clean install -P embedded 时出现以下错误，我以前从未使用过 Maven，实际上几乎不明白它试图告诉我什么。有人可以帮我解决吗？

我遇到了同样的问题，但后来我找到了非常简单的解决方案。

step1 - 从http://maven.apache.org/download.cgi下载所需的 maven 文件夹（我已经下载了 Maven 2.2.1 (Binary tar.gz)）

第 2 步 - 提取 tar 并将文件夹放到您想要的位置（即 /usr/lib/）

step3 - 更新你使用它的maven路径（在我的例子中是.bashrc）

基本上问题是您的 Maven 已损坏，您需要按照上述步骤来解决它。:)

检查您是否正确设置了 M2_HOME 变量，如安装说明中所述。

您的 Maven 安装已损坏。卸载它，重新下载 maven，确认 md5 校验和匹配，安装它并重试。

（类似的问题线程）

编辑：另一种选择是您从损坏的回购中下载了一些东西。如果重新安装 maven 不能解决问题，请检查您是否使用了有问题的存储库（最好在此处报告您配置的 pom 依赖项）。也有过这样的案例。
