在 IDE 中构建和运行良好：

如何从 CLI 构建和运行此项目？

类似于：

Maven: lifecycle phase to run a program?

【问题讨论】：

部署目标失败，您的 IDE 没有尝试运行...

您将尝试部署到的存储库添加到 pom。

根本不尝试添加或使用存储库。但是，是的，查看distributionManagement 标签。

@f1sh 啊，我明白了。那么什么目标会起作用？奇怪的是 NB 没有部署。

***.com/a/46866373/262852 运行。

【参考方案1】：

您的错误消息说 exec-maven-plugin 找不到主类。您的 pom 似乎没有将其列为插件。 对于完整的包名，不要包括 src.main.java，只需以域开头。通常是 com,org 等。
