JFreechart unresolved dependency

Hi,
I have added the jfreechart into my vaadin application.
Added ivy dependecny into ivy.xml file of the my project
Then added the dependency into gradle.build file “compile” in the form of
compile group:‘org.vaadin.addon’, name:‘jfreechartwrapper’,version:‘3.0.1’

while build the project,It shows the below error

What went wrong:
Could not resolve all dependencies for configuration ‘:compile’.

Could not find org.vaadin.addon:jfreechartwrapper:3.0.1.
Searched in the following locations:
