我从我的 NetBeans GUI 创建了一个报告，它工作正常，但突然间编译器现在显示错误。

                dataSource.add("Date","22-Feb-2013");

        return dataSource;
    }   


    public static void main(String[] args) {
        new DReportSample();
    }
}

这段代码在几个小时前运行良好。但现在它突然显示错误：附加屏幕截图

在此处输入图像描述

它在 report() 和其他部分也显示了同样的错误。基本上它无法识别动态报告库的各种类和字段，尽管该库已成功导入，但几个小时前它运行良好。

我使用动态报告的方式是添加如下库：

1) Downloaded dynamicreports-3.1.0-project-with-dependencies
2) Unzipped
3) In my Netbeans Project
Libraries -> Add Jar/folder -> Selecting all files from dynamicreports-3.1.0-project-with-dependencies\dynamicreports-3.1.0\lib
Libraries -> Add Jar/folder -> Selecting all files from dynamicreports-3.1.0-project-with-dependencies\dynamicreports-3.1.0\dist

在此处输入图像描述

它工作正常，但后来我更改了保存 dynamicreports-3.1.0-project-with-dependencies 的文件夹的名称，因此它给了我添加库的参考错误。所以我再次将其更改为以前的名称，但从那以后我得到了显示的错误。

我已经尝试了一切，构建新项目并按照提到的步骤或重新下载新的 dynamicreports-3.1.0-project-with-dependencies 并再次按照步骤操作。但似乎没有任何效果，因为我离完成我的项目如此接近，这令人沮丧。

任何人都可以帮忙吗？

谢谢

好的。。解决了。。

下面的行被删除导致错误：

导入静态 net.sf.dynamicreports.report.builder.DynamicReports.*；
