我有一个Netbeans Maven Java项目，我使用Jasper报告。虽然在Netbeans中一切都运行良好，但是当我运行带有依赖项的jar文件程序时，我会尝试从数据库获取数据报告。当我按下按钮返回报告中两个日期之间的数据时，程序抛出错误 - 线程中的异常＆＃34; AWT-EventQueue-0＆＃34;例外：从线程＆＃34; AWT-EventQueue-0＆＃34; 中的UncaughtExceptionHandler抛出net.sf.jasperreports.engine.JRRuntimeException。当我尝试从列表中获取数据（showMessageDialog）时，我从DB获得的数据一切正常。我使用shade插件创建我的jar文件。我添加了POM文件代码。我只看到＆＃34; net.sf.jasper2docx＆＃34;，但没有其他jasper依赖。也许问题是POM中的依赖声明？在项目依赖项中，我有jasper2docx-apache-poi，jasper2docx-api和jasperreports-6.1.0 jars。

2.4.2升级后，尝试清洁然后包装。
我不确定Netbeans是否同时调用它的构建。也许从命令行尝试'mvn clean package'，看看你生成的超级jar是否正常。在目标文件夹

OP发现的解决方案：
必须添加Jasper报告插件依赖项。如果没有它，Jasper报告将无法100％工作。
<dependency> <groupId>com.alexnederlof</groupId> <artifactId>jasperreports-plugin</artifactId> <version>2.0</version> </dependency>
答案 2 :(得分：0)
我遇到了类似的问题，这都是因为我的字体jar和相同的jasper项目在同一路径中有一个公用文件。然后，一个文件将覆盖另一个文件，并进入JRERuntime异常。
我所做的是合并文件，我使用了shadowJar，并且这样工作。您应该为Maven寻找类似的东西
shadowJar {
mergeServiceFiles()
mergeServiceFiles('jasperreports_extension.properties')
}
