Difference between groupids net.sf.jasperreports and jasperreports

[Tailor_bird]

I was using net.sf.jasperreports as the group is for the version 3.6.0.

<dependency>    <groupId>net.sf.jasperreports</groupId>    <artifactId>jasperreports</artifactId>    <version>3.6.0</version></dependency>[/code]

For some reasons, I was asked to downgrade to the version 3.5.2.

<dependency>    <groupId>jasperreports</groupId>    <artifactId>jasperreports</artifactId>    <version>3.5.2</version></dependency>[/code]

 

When I have taken a build it is observed that some of the jar files are missing like,

jcommon-1.0.15.jarjdtcore-3.1.0.jar[/code]

Can anyone please explain me why this is happening. Are these jars are coming from `net.sf.jasperreports`? Please explain the difference between using groupids `jasperreports` and `net.sf.jasperreports`. And what is the impact on missing these jars?
