java如何修复mavenpackaged jar报告的错误：无法找到或加载主类。\公式1。0快照。罐子

Question

我正在尝试使用Maven打包我的JavaFX应用程序，使用exec运行它：java没有问题，运行Maven-package不会产生任何错误。但当我想要执行runnable jar时，它会返回错误“error:找不到或加载主类”。\FormulaTelemetryApp-1.0-SNAPSHOT。第二部分是我想要执行的jar

在我包含POM的下面，我已经开始寻找解决方案，这是我偶然发现maven jar插件的地方，但包含它并没有解决问题。我还尝试过清理项目并再次编译/打包，但这也没有改变任何事情

正如你可能注意到的，我对Maven（尝试自学）相当陌生，所以POM中可能有一些奇怪的东西

Answer 1

正如评论中所说，问题有两个方面：一方面需要一个胖罐子，maven shade插件用于此。除此之外，还需要一个启动程序类（非应用程序扩展类）作为主类，正如对本question的回答中所述
