Question

我有一个报告项目，可以编译，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。我有一个循环依赖的问题，其中一个模板需要在同一个项目中的scriptlet类，但是在报告之前没有编译scriptlet类，我在编译期间得到了ClassNotFound异常。有没有办法在模板或其他一些解决方法之前首先编译类，除了声明系统依赖于以前编译的jar版本？

这是我的pom：

Answer 1

这可能有点晚了，但我想你可以尝试将jasperreports-maven-plugin的执行绑定到以后的maven构建阶段。

默认情况下，它在generate-resources阶段运行，此时java类尚未编译。

查看this页面上代码框下方的段落。

通过Maven在同一项目中编译JasperReports jrxml与scriptlet依赖项
