“启动配置”尝试导出可运行jar时显示为空白？ [英] "Launch Configuration" Shows up Blank When Trying to Export Runnable Jar?

问题描述

我已经在过去的工作，但现在每当我选择文件>导出...> Runnable JAR File 并选择下拉菜单启动配置，我得到的是一个空白的栏。

I've gotten this to work in the past, but now whenever I choose File > Export... > Runnable JAR File and select the drop-down menu "Launch Configuration", all I get is a blank bar.

如何让我的主类显示出来？

How can I get my main class to show up?

推荐答案

请执行in main（...），选择Run-> Run并运行你的程序。

On the class you want to have main(...) executed in, choose Run->Run and run your program.

这个过程创建一个启动配置你可以使用you make it shared）

This process creates a launch configuration you can use (and save too, if you make it shared)
