从Eclipse导出的可运行JAR文件似乎不执行 [英] Exported runnable JAR file from Eclipse doesn't seem to execute
问题描述
（免责声明：我不是Java程序员，真的很不了解我在Eclipse中做什么）
(Disclaimer: I am not a Java programmer, and really have very little idea what I'm doing in Eclipse)
我在Eclipse中黑客攻击了一个应用程序而我已经完成并作为一个运行良好的JAR导出。我没有收到任何笔记或发表任何意见。
I hacked out an application in Eclipse a while back which I finished off and exported as a JAR which runs nicely. I didn't take any notes or make any comments.
现在是对项目进行一些更改的时候了，但是我必须重新加载它，因为我的电脑已经被擦除，所以一些设置等可能已经改变了。
The time comes to make some changes to the project but I have to reload it all again because my PC has since been wiped so some settings etc have probably changed.
无论如何，它都可以从Eclipse运行得很好。但是当我作为一个可运行的JAR导出，并双击运行应用程序，似乎不执行。
我可以看到有javaw运行的实例，但不会出现窗口。没有错误。 Nada。
I can see that there is an instance of javaw running, but no window appears. No errors. Nada.
正如我所说，它在Eclipse中精美地工作。任何想法？
As I said, it works beautifully in Eclipse. Any ideas?
我不知道如何检测发生了什么 - 正如我所说，我不是一个java程序员： - ）
I have little idea of how I can detect what is going on - as I said, I am NOT a java programmer :-)
推荐答案
然后，您可以将问题标记为关闭：
Ok then, so you can mark the question closed:
如果您的Java安装注册了.jar扩展，它将尝试运行Jar（我猜这是发生了什么）。但是它会安静地这样做。
If your Java installation is registered for the .jar extension it will try to run the Jar (i guess that's what's happening). But it will do so quietly.
为了看到发生了什么（错误等等），你应该尝试从命令行运行它与 java -jar myfile.jar 。
In order to see what's happening (errors and such) you should try to run it from the command line with java -jar myfile.jar.
