JavaBuilder 处理 CoreException
我正在使用 Eclipse。在我开发的过程中一切都很好，但是我有两天遇到了一些奇怪的问题。我有一个包含多个包的子项目。我想在包之间使用一些类并且 Eclipse 可以识别导入。但是，当我尝试导入时，却显示无法解析导入。我看到了日志文件，并得到了以下几行：
org.eclipse.core.runtime.CoreException: File not found: E:\eclipse\PasarelaCARTIF\classes\es\cartif\zigbee\driver\Controller.class.

这是第一次发生。问题是什么？
多谢！祝你今天过得愉快！
I am working with Eclipse. All was right during I was developing, but I have two days with some strange problems. I have a subproject with several packages. I want to use some classes between packages and Eclipse recognizes the imports. However, when I try to import, it shows that the import cannot be resolved. I saw the log file and I get the next lines:
org.eclipse.core.runtime.CoreException: File not found: E:\eclipse\PasarelaCARTIF\classes\es\cartif\zigbee\driver\Controller.class.

It is the first time it occurs. What is the problem?
Thanks a lot! Have a nice day!

远射！尝试在 Eclipse 中进行清理，然后构建您的项目。从具有稍后编译所需的类文件的项目开始。
Eclipse 常常会搞乱您的项目，您不得不求助于奇怪的方法，例如上面描述的方法。被迫创建一个新的工作区并将项目导入其中，然后它神奇地再次开始工作，这并不是闻所未闻的。
查看您所依赖的项目中的 .java 文件是否真正编译为并在其他项目的错误消息指示的所需文件夹中创建 .class 文件。
A long shot! Try clean in eclipse then build your projects. Starting with the project which have the class files needed later in the next compilation.
More than often eclipse messes up your project and you have to resort to strange methods such as the one described above. It's not unheard of to be forced to create a new workspace and import you project there and then it magically starts working again.
Look if your .java file from the project you have dependencies on really compiles to and creates a .class file at the desired folder indicated by the error message from the other project.
另一个远景：
我认为你的硬盘可能崩溃了。
在过去的几天里，我也有过同样的经历，以及坏扇区导致我的虚拟机崩溃等。因此，检查新的工作空间可能是短期解决方案。
Another long shot:
I think your hard drive may be crashing.
I've had the same experience, along with bad sectors crashing my VM, etc for the past few days. Thus, checking out a new workspace can be short term solution.
执行 Clean 为我解决了这个问题，但前提是我首先物理删除了
bin目录。Performing a Clean resolved this issue for me, but only after I physically deleted the
bindirectory first.
