导出的GUI项目不会打开/运行，使用eclipse氧气Java导出

标签： java eclipse windowbuilder

我从Eclipse Oxygen导出GUI项目时遇到了麻烦。起初我尝试通过导出＆gt; Runnable Jar文件＆gt; Main Class导出我的项目，但是当我尝试打开我的程序时，没有任何显示。然后我尝试通过在那里指定一个Main方法在自己的类中打开GUI，并且我不断收到我在标题中放入的错误。任何帮助，将不胜感激。我会在这里发布我的两个课程。

我也使用WindowBuilder插件来构建我的GUI。

答案 0 :(得分：0)

原来，winrar不喜欢runnable jar文件。我曾尝试右键单击该文件并将其作为Java应用程序SE二进制文件运行，但它不起作用。所以在@Adam Horvath提到它对他有用之后我将导出的jar设置为默认的java jar并且它打开就好了。
