我有一个报告项目，它被编译、打包并包含在战争中。我使用 jasperreports-maven-plugin 编译报表项目中的 JasperReports 模板。我有一个循环依赖问题，其中一个模板需要在同一个项目中的 scriptlet 类，但 scriptlet 类在报告之前没有被编译，并且在编译期间我得到一个 ClassNotFound 异常。除了向先前编译的 jar 版本声明系统依赖项之外，是否有办法在模板或其他解决方法之前先编译类？

这是我的pom：

这可能有点晚了，但我认为您可以尝试将 jasperreports-maven-plugin 的执行绑定到稍后的 maven 构建阶段。

默认情况下，它在 generate-resources 阶段运行，此时 java 类还没有被编译。
