jar 工作正常，但 exe 显示异常

问题描述

我目前正在尝试使用 launch4j 制作 exe 以使用 jasper 生成报告。当我运行可运行的 jar 时，它完美地显示出来。但是当我运行 exe 文件时，总是会出现与 jar 依赖项相关的异常。我在通过launch4j创建exe时显示了jre文件夹。尽管如此，我还是将以下 jars 文件添加到我的构建路径中，

• jasperreports-5.6.0.jar
• commons-logging-1.1.jar
• commons-beanutils-1.8.2.jar
• commons.digester-2.1.jar
• commons-collections-3.2.1.jar
• groovy-all-2.0.1.jar
• jdt-compiler-3.1.1.jar
• jfreechart-1.0.12.jar
• jcommon-1.0.15.jar
• iText-2.1.7.js2.jar

该程序生成了与集合相关的未找到类异常。我的主要目标是通过使用 jrxml 文件生成报告。我正在使用 iReport 5.6.0 生成 jrxml 文件。任何帮助表示赞赏。错误堆栈跟踪如下;
