RAD 项目构建问题：由于“无法删除”而未构建该项目
我在 Windows XP m/c 上使用 RAD 7.5。每当我尝试清理/构建项目时，我都会收到一条消息，提示
由于“无法删除 'D:\Documents and Settings\User\My Documents\project\exe\EXE”，该项目未构建\WebContent\WEB-INF\classes\BusinessRules.properties'。”。修复问题，然后尝试刷新此项目并构建它，因为它可能不一致
要解决此问题，我需要停止服务器，手动删除此文件并删除它。然后构建&重新启动服务器。知道为什么我会遇到这个问题吗？
I am using RAD 7.5 on a Windows XP m/c. Whenever I try to do a clean up/build the project, I get a message saying
The project was not built due to "Could not delete 'D:\Documents and Settings\User\My Documents\project\exe\EXE\WebContent\WEB-INF\classes\BusinessRules.properties'.". Fix the problem, then try refreshing this project and building it since it may be inconsistent
To overcome this problem, I need to stop the server, manually delete this file & then build & restart the server. Any idea why I am facing this issue?

我在 RAD 8.0 中遇到过这个问题，但不像你那么一致。第二次构建尝试几乎总能解决我的问题。
尽管 Eclipse bug 跟踪站点上有很多关于此问题的参考资料，但我读过的所有 bug 都没有明确的原因答案。有人猜测这可能是由于文件句柄泄漏造成的。该问题似乎是从 Eclipse 版本 3.6.1 开始出现的。我不确定 RAD 7.5 到底基于哪个 Eclipse 版本，但我相信它是 3.6.1 或更高版本。
该问题是否仅在部署应用程序且服务器正在运行时出现？我想知道在服务器关闭的情况下您是否会得到相同的结果。
不幸的是，我能提供的唯一具体建议是尝试经常刷新项目，也许创建一个新的工作区——这有点像黑客，但创建一个新的工作区解决了我遇到的一些非常奇怪的 RAD 问题。
以下是来自 Eclipse 错误跟踪站点的一些错误报告：

I've experienced the issue in RAD 8.0, but not nearly as consistently as you. A second build attempt nearly always resolves the problem for me.
Although there are a number of references to this issue on the Eclipse bug tracking site, none of the bugs I've read have a definitive answer on the cause. There is some speculation that it may be due to a file handle leak. The problem appears to have begun around Eclipse version 3.6.1. I'm not sure exactly which Eclipse version RAD 7.5 is based on, but I believe it is 3.6.1 or later.
Does the issue only occur when the application is deployed and the server is running? I was wondering if you'd gotten the same results with the server shut down.
Unfortunately, the only concrete suggestions I can offer are to try refreshing the project frequently, and perhaps creating a new workspace -- its a bit of a hack, but a creating a fresh workspace has fixed a few really odd RAD issues I've encountered.
Here are a couple of the bug reports from the Eclipse bug tracking site:
