Question

我正在制作一个WEB系统（Windows 32x上的最新Java8和eclipse_mars.2）。并且该系统具有文件下载功能（文件由java制作）。当文件（用于下载）放在myproject / WebContent / tempfolder中时，用户可以通过URL访问这些文件，并可以获取文件。

（我想在Eclipse Control下管理Web系统。不在Tomcat上）

但eclipse不会立即识别文件（由java制作）。在我的准备服务器条件下，当我按下这个系统上的下载按钮时，我必须等待大约7--8秒。

用户不会等待7--8秒（我认为）。

（eclipse工作区设置（（窗口） - （首选项） - （常规） - （工作区））是这样的： ·在本机挂钩或轮询上刷新（选中） ·访问时刷新（已检查）
）我在许多WEB网站上研究了programatcally刷新插件，但我找不到这个。

所以我开始制作Eclipse-Plugin，使myproject / WebContent / tempfolder以编程方式刷新，就在java程序设置好要下载的新文件之后..

（现在，工作区名称是“myworkspace_m”。 Dinamic Web Project名称是“myproject”。要刷新的文件夹是“myproject / WebContent / tempfolder”。插件项目名称是“myprojectsupport”。刷新程序是“RefreshFolder.java”。）

Eclipse插件项目中的程序如下所示。（它不起作用）

package myprojectsupport;
import org.eclipse.core.resources.*;
import org.eclipse.core.runtime.CoreException;
import org.eclipse.core.runtime.IPath;

public class RefreshFolder {

    public void main() throws CoreException {
        IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
        IProject project = root.getProject("myproject");
        IPath path = project.getFullPath().append("WebContent/tempfolder");
        IFile iFile  = root.getFile(path);

        iFile.refreshLocal(IResource.DEPTH_INFINITE, null);
   }
}

当我运行此程序时，我打开了myprojectsupport \ META-INF \ MANIFEST.MF，在OverView选项卡上，我按下“启动eclipse应用程序”链接

然后打开另一个日食窗口，控制台说像吼叫。但我无法理解这个控制台日志。请告诉我该怎么办。（抱歉英文不好）
