The jasperreports-maven-plugin repeats the jasperreports dependency. I had your problem when I changed the version of my jasperreports dependency but did not also change it in the dependency of the jasperreports-maven-plugin.
jasperreports-maven-plugin 重复了 jasperreports 依赖项。当我更改 jasperreports 依赖项的版本但没有在 jasperreports-maven-plugin 的依赖项中更改它时，我遇到了您的问题。

Just delete jasperreports-javaflow*.jar from your classpath during report compilation.
The error should disappear.
只需在报告编译期间从您的类路径中删除 jasperreports-javaflow*.jar。
错误应该消失。
