为什么我得到异常java.lang.NoClassDefFoundError org / codehaus / groovy /？[重复]

Question

我刚刚尝试了Jasper
Report，我正在关注此站点的教程

我也下载了示例源，然后运行它，没有错误。但是，当我使用创建自己的报告时iReport，请对其进行编译，然后将.jasper文件添加到我的项目中。还有exception，当我运行我的程序：

这是我用于显示报告的按钮操作（这只是示例，报告仅包含一个带有参数的文本：outputText）：

Map params = new HashMap();
params.put("outputText", "Hello world");
try {
        JasperPrint printer = JasperFillManager.fillReport(getClass().getResourceAsStream("report2.jasper"), params, new JREmptyDataSource());
        JasperViewer jv = new JasperViewer(printer);
        jv.show();
    } catch (JRException ex) {
        ex.printStackTrace();
    }

如果有dependency问题，我已经将所有需要的jar导入到我的项目中，当我使用.jasper该教程中的文件时没有问题，是否是因为版本不同iReport？

Answer 1

您需要使用CallSiteArray类的其他Jar包。
