【问题描述】：
我正在尝试在 Eclipse Luna 环境中使用 maven 来组装可执行 jar 并将其部署到 Raspberry Pi，我发现看起来像一个合适的 Maven 脚本，但 Maven 似乎没有找到它的第一个插件和声明构建失败，请参阅下面的控制台日志：-

我已经在 Eclipse 上安装了 Maven，并检查了插件文件是否在我的 PC 上，并且类路径已设置（这是文件所在）
C:\Users\GJWood\.m2\repository\org\apache\maven\plugins\maven-assembly-plugin\2.2-beta-5
我也尝试过引用引用库中的 jar 文件
一切都无济于事！
【问题讨论】：
-
你是怎么称呼 Maven 的？
-
在家访问所以没有代理问题。
-
Maven 通过在 Eclipse 中运行右键 m2 选项调用
-
明确我是在 Eclipse 中运行 M2Eclipse 而不是命令行 maven
