动态jasper或jasper报告不适用于maven依赖项：无法读取com.itextpdf：itext-pdfa：jar：5.5.0的工件描述符

Question

I haven't used dynamic jasper reporting tool before. I am trying to use dynamic jasper with my springboot maven project. I took the maven dependency from the dynamic jasper official site.

http://dynamicjasper.com/download/

It doesn't work for some reason.

My pom.xml

when i add this dependency for dynamicjasper i am getting bellow error.

Failed to read artifact descriptor for com.itextpdf:itext-pdfa:jar:5.5.0

Tried both jasper and dynamicjasper dependencies and both give me an error. even tried downloading somegithub examples and their also i get the same error. How do i use dyanmic jasper in my Springboot project.

Answer 1

Dynamic jasper have a range version dependency to jasper report, to not have maven select what jasper-reports version to use, I would include desired version of jasper-reports in pom.xml (eg. latest versions supported 6.4.1)

<dependency>
    <groupId>net.sf.jasperreports</groupId>
    <artifactId>jasperreports</artifactId>
    <version>6.4.1</version>
</dependency>

In this version there is no dependency to itext-pdfa:jar:5.5.0 , that dependency is AFIK only present in version 6.0.x .

There is a back story related to the itext library, licenze issues etc. It was "open source" until version 2.1?, jasper-reports then maintained own version, got permission to use latest version (in version 6.0.x), permission was withdrawn? (I actually don't know exactly what happen, but I can immagine), in versions >6.1 jasper reports is using again it's own modified version 2.1.7.js6
