在 NetBeans 6.9 中找不到主类 [英] Can't find main class in NetBeans 6.9

问题描述

每当我加载 NetBeans 6.9(以前的版本也发生类似的错误)时，我让 NetBeans 完成扫描我的项目，一旦完成，我尝试运行一个配置文件，该配置文件指向一个具有 main 方法的类，NetBeans 总是说 main没有找到类，即使它在错误弹出后显示在类列表中.

Whenever I load NetBeans 6.9 (similar errors happened on previous versions also) then I let NetBeans finish scanning my projects and once it's done I try to run a profile which points to a class with a main method, NetBeans always says the main class is not found, even though it shows up in the list of classes once the error pops up.

如果我从列表中选择类并点击确定，同样的错误再次发生(未找到主类).

If I select the class from the list and hit OK, the same error happens again (main class not found).

如果我编译主类，我仍然遇到同样的问题.

If I compile the main class, I still get the same problem.

如果我重建整个项目，我想我仍然会遇到同样的问题.-> 当我编译主项目时，它会编译所有项目，即使是那些关闭的项目.这是怎么回事?

I think I still get the same issue if I rebuild the entire project. -> when I compile the main project it compiles all projects, even those that are closed. What is going on?

到目前为止，我找到的唯一解决方法是关闭项目并重新打开它，然后等待项目扫描再次完成.

The only way I have found so far to work around this is to close the project and re-open it and wait for the project scan to finish again.

这太令人讨厌了.有没有办法解决这个问题?

This is incredibly annoying. Is there a fix for this?

我注意到的另一件奇怪的事情是我的项目似乎构建了错误的 JAR 文件名(尽管如果我执行上述关闭并重新打开项目的步骤，它仍然有效).我有两个不同名称的项目，即使在关闭另一个项目并重新启动 NetBeans 很多次之后，当我构建第一个项目时，它仍使用已关闭很长时间的第二个项目的 JAR 文件名.

Another strange thing I noticed is that my project seems to be building into the wrong JAR file name (though if I do the above step of closing and reopening the project it still works). I have two projects with different names, and even after having closed the other project and restarted NetBeans a lot of times, when I build the first project it uses the JAR file name for the second project that has been closed for a long time.

推荐答案

我通过删除 NetBeans 的缓存修复了一个非常相似的行为.删除文件夹User.netbeans6.9varcacheindex.

I fixed a very similar behaviour by deleting NetBeans's cache. Delete the folder User.netbeans6.9varcacheindex.
