为什么我会收到异常 java.lang.NoClassDefFoundError org/codehaus/groovy/？ [复制]

Question

我刚刚尝试了 Jasper Report，我正在学习 this site 的教程

我还下载了示例源，然后运行它并没有出现错误。但是当我使用iReport 创建自己的报告时，编译它，并将.jasper 文件添加到我的项目中。运行程序时有exception：

这是我显示报告的按钮操作（这只是示例，报告只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();
    }

如果是dependency的问题，我已经将所有需要的jar导入到我的项目中，当我使用该教程中的.jasper文件时没有问题，是因为iReport的版本不同还是其他原因?

Answer 1

或者，您可以更改 .jrxml 文件，查找

language="groovy"

并将其更改为

language="java"

Answer 2

可能是版本不匹配。 如果您想知道您需要哪个版本的 Groovy，您可以查看 Jasper 的 Maven 存储库：

http://mvnrepository.com/artifact/net.sf.jasperreports/jasperreports/4.6.0

从这里您可以看到 Jasper 4.6.0

需要 Groovy 1.7.5

Answer 3

您需要使用 CallSiteArray 类的附加 Jar 包。

http://groovy.codehaus.org/Download

Answer 4

我在使用 Jasper iReport Tool 5.6.0 时遇到了同样的问题，我的语言是 Java，我将正确的 jasper 报告库降级为 iReport Tool 5.1.0，它的工作原理就像一个魅力......希望状态保持不变所以..

Answer 5

无需更改库，如果是 Ireport 5.X 版本，您可以在主报告属性的语言部分更改它，只需从 groovy 更改为 java，报告不会出现任何错误。

Answer 6

简单的答案

步骤：

1 选择您的根文件夹，即来自 Report Inspector 的 report1.jsxml （Windows->报告检查器） 2 转到属性标签并点击语言标签然后选择JAVA

编译并预览您的应用程序已启动...
