“启动配置”试图导出Runnable Jar时显示空白？ [英] "Launch Configuration" Shows up Blank When Trying to Export Runnable Jar?

问题描述

我已经得到了这个工作过去，但现在每当我选择文件>导出...> Runnable JAR文件并选择下拉菜单启动配置，我所得到的只是一个空白栏。

如何让我的主要课程出现？

解决方案

在Package Explorer面板中，右键单击要执行main（...）的类，然后选择 Run as - > Java应用程序运行您的程序。

此过程创建可以使用的启动配置（并保存，如果您共享） / p>

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.

How can I get my main class to show up?

解决方案

In the Package Explorer panel, right-click on the class you want to have main(...) executed in and choose Run as -> Java Application to run your program.

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