its path issue try to put report in project directory. Your report is fine./sites/all/libraries/ckeditor/plugins/smiley/images/thumbs_up.png

Try using the following jasper version.

<dependency>

  <groupId>net.sf.jasperreports</groupId>

  <artifactId>jasperreports</artifactId>

  <version>6.14.0</version>

</dependency>

If maven throws the error "Could not transfer artifact net.sf.jasperreports:jasperreports:pom:6.14.0 from/to central (https://repo.maven.apache.org/maven2): Connection reset" please download the artifact files directly from https://repo1.maven.org/maven2/net/sf/jasperreports/jasperreports/6.14.0/ and add it manually to the local repository.
