虽然来自 IDE 的项目 executes，但如何创建 JAR 以便真正运行 hello world 类型的控制台应用程序？

显然只需要为清单指定Main-Class 条目。
只关注packagephase：
运行 Maven 工具 Maven 阶段
虽然不是一个完整的列表，但这些是最常见的 执行的默认生命周期阶段。
validate：验证项目是否正确且所有必要 资料可用 compile：编译源代码 项目测试：使用合适的单元测试编译后的源代码 测试框架。这些测试不应该要求打包代码 或部署的包：获取编译后的代码并将其打包到它的 可分发的格式，例如 JAR。集成测试：过程和 如有必要，将包部署到集成环境中 可以运行测试 verify：运行任何检查以验证包是否有效 并符合质量标准安装：将包安装到本地 存储库，用作本地部署的其他项目中的依赖项： 在集成或发布环境中完成，复制最终 打包到远程存储库以与其他开发人员共享 项目
