Eclipse Unable to Launch, the selection cannot be launched, and there are no recent launches
提问by Devid
I am getting the above error when i try to launch a Project which i checked out from SVN Repository. When i make my own Java Project on eclipse with a main class everything works fine, but when i try to run the main class from my repository project i get the above message.
当我尝试启动从 SVN 存储库检出的项目时，出现上述错误。当我使用主类在 Eclipse 上创建自己的 Java 项目时，一切正常，但是当我尝试从我的存储库项目中运行主类时，我收到上述消息。
I did not have such a problem before. Repository projects were running fine, i got suddenly this error yesterday and after searching the internet i still can't fix it.
我以前没有这样的问题。存储库项目运行良好，昨天我突然收到这个错误，在网上搜索后我仍然无法修复它。
I have now 3 Projects on eclipse, homewhich is a java project made by me and two projects from repository lechand kramerspitz.
我现在在 eclipse 上有 3 个项目，home这是一个由我制作的 java 项目和来自存储库lech和kramerspitz 的两个项目。
Under Run-> Run Configuration->Java Application->Project Browse i see only the home Project which i made, although the two other repository projects are also in my workspace but they don't show up. (Run As is empty)
在“运行”->“运行配置”->“Java 应用程序”->“项目浏览”下，我只看到我创建的主项目，尽管其他两个存储库项目也在我的工作区中，但它们没有显示出来。（运行方式为空）
Does anyone know what i should do? Re-installing Eclipse does not help, cause the problem remains.
有谁知道我应该做什么？重新安装 Eclipse 没有帮助，导致问题仍然存在。
The only difference i see is that the two repository projects are missing a .classpath file. Please help!
我看到的唯一区别是两个存储库项目缺少一个 .classpath 文件。请帮忙！

As it seems I can't just check out on the project from the SVN repository. I have to choose from the project a specific project to check out, then everything works fine.
看来我不能只是从 SVN 存储库中查看该项目。我必须从项目中选择一个特定的项目来检查，然后一切正常。

I Windows 8 and run Eclipse C++ Kepler (Toolchain = MinGW). This is what I did for the same message that you got and it worked for me: In editor's screen, right-click>Run As>Local C/C++ Application
我在 Windows 8 上运行 Eclipse C++ Kepler（工具链 = MinGW）。这就是我对您收到的相同消息所做的操作，它对我有用：在编辑器屏幕中，右键单击>运行方式>本地 C/C++ 应用程序

public class HelloWorld {
public void main(String[] args) {
System.out.printf("Hello world!!!");
}
}
Also if you omit the statickeyword, the problem happens.
此外，如果您省略static关键字，问题就会发生。
回答by s.n
Sometimes it happens when you forget to write "String[] args" in the main parenthesis
有时当您忘记在主括号中写入“String[] args”时会发生这种情况
public class Hello {
public static void main(){
System.out.println("Hello");
}
}
Code above would cause a similar problem
上面的代码会导致类似的问题
