无法运行Java应用程序。主要没找到 [英] Cannot run Java application. Main not found

问题描述

我是java的新手，我需要运行一个我从网上下载的应用程序。有问题的应用程序是在这里找到的spinn3r客户端： http://code.google.com/p/spinn3r-client/downloads/detail?name=spinn3r-client-3.4.06.tar.gz

I am completely new to java and I need to just run an application I downloaded off the internet. The application in question is the "spinn3r" client found here: http://code.google.com/p/spinn3r-client/downloads/detail?name=spinn3r-client-3.4.06.tar.gz

我解压缩了tar.gz并找到了一个.jar文件。然后我跑了：

I extracted the tar.gz and found a .jar file. I then ran:

java -jar applicationName.jar

我收到以下错误：

no main manifest attribute, in spinn3r-client-3.4.06.jar

如何解决此问题？

推荐答案

正如@Alderath所提到的，这主要是一个可以在自己的应用程序中使用的API。尽管如此，jar文件还包含测试客户端，您可以按如下方式启动：

As @Alderath mentioned, this is primarily an API which you can use in your own applications. Nevertheless, the jar file also contains a test client which you can launch as follows:

$ java -cp spinn3r-client-3.4.06.jar com.spinn3r.api.Main
Usage: com.spinn3r.api.Main [OPTION]

Required params:
...

由于这不是可执行jar 文件，你需要通过必需的jar文件和显式包含 main 方法的类。

Since this it is not an executable jar file, you need to pass the required jar files and the class which contains the main method explicitly.
