在Eclipse中调试我的Java代码时，我得到“Source not found”

I'm trying to debug my Java application in Eclipse however when I hit a breakpoint I simply see the following instead of my source:

我正在尝试在Eclipse中调试我的Java应用程序,但是当我遇到断点时,我只是看到以下内容而不是我的源代码:

If I change the stack frame in the Debug window then I can see the function name change in the tab - this is definitely my code, the line number is correct and I'm using the latest build but I still can't get Eclipse to show the source (despite it being open in another tab!)

如果我在调试窗口中更改堆栈帧,那么我可以看到选项卡中的函数名称更改 - 这绝对是我的代码,行号是正确的,我使用的是最新版本,但我仍然无法将Eclipse转换为显示源(尽管它在另一个选项卡中打开!)

I'm new to Eclipse and so I'm struggling to find my way around, but everything that I've stumbled across so far seems fine to me.

我是Eclipse的新手,所以我很难找到自己的方式,但到目前为止我遇到的所有事情对我来说都很好。

What might cause this to happen and how can I fix it?

可能导致这种情况发生的原因以及如何解决?

Sounds like the 'source lookup path' section if you edit the debug configuration isn't setup correctly?

如果编辑调试配置未正确设置,听起来像'源查找路径'部分?

We had the same problem and none of the suggestions above worked. What did work, was deleting the local workspace and from Eclipse checking out from the repository again. The problem occured for everybody previously working with Netbeans and making the switch to Eclipse.

我们遇到了同样的问题,上述建议都没有奏效。什么工作,是删除本地工作区和Eclipse再次从存储库中检出。以前使用Netbeans并切换到Eclipse的每个人都遇到了这个问题。

对于本地项目,我通过选择Debug Configurations中的“Resolve Workspace artifacts”复选框来解决它。

When I faced this problem for the very first time, I've already done all the steps mentioned here. Curiously, my problem happened when I've copied a project into another place. Anyway, the debug starts to work without warnings, after simply remove all breakpoints that was originated from the original project. Sorry about my English , I'm not fluent.

当我第一次遇到这个问题时,我已经完成了这里提到的所有步骤。奇怪的是,当我将项目复制到另一个地方时,我的问题就发生了。无论如何,在简单地删除源自原始项目的所有断点之后,调试开始工作而没有警告。抱歉我的英语,我不会流利。
