Vaadin 7 Failed to retrieve com.vaadin:vaadin-client based on project POM

Vaadin 6 / 7 / 8
1

Using NetBeans 8.2 something went wrong.

I got this message :

--- vaadin-maven-plugin:7.6.7:compile (default-cli) @ SodaCrawlerUI7 --- GWT plugin is configured to detect modules, but none were found. Failed to retrieve com.vaadin:vaadin-client based on project POM Using com.vaadin:vaadin-client version 7.6.7 Failed to retrieve com.vaadin:vaadin-client-compiler based on project POM Using com.vaadin:vaadin-client-compiler version 7.6.7 I’m using vaadin 7 and I want to use the new version of V-Leaflet.
In the past I’ve used this add on without any problem, so I’ve tryed also to use the same pom ( yes I’m using maven) of my previous project ( so same version of maven, same version of vaadin, plugins and add-on) but the problem persists.

This is my pom :

[/code]This is the pom generated by default from the plugin. I've tryed hard to change something but the same errors occurs.

Solved… the problem is the Vaadin version.
Using NetBeans 8.1 I’ve created a new Project with vaadin 7.7.8 and it’s realtive pom.
