I have the Vaadin-maven-plugin-7.7.15 as a dependency. but when I run

mvn vaadin: upgrade8 i get the following:

org.apache.maven.plugin.prefix.NoPluginFoundForPrefixException: No plugin found for prefix ‘vaadin’ in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo]
available from the repositories [local (C:\Users\Papa.m2\repository), central (http://repo.maven.apache.org/maven2)]

I have no idea why this is the case and there is literally no example on Netbeans based migration. VAADIN needs to realize that a lot of us use Netbeans

Aby ideas?

You need the Vaadin 8 version of the Vaadin Maven Plugin to run the migration tool.

Thanks Olli…just to clarify I should change the dependency to 8.x.x and one more thing do I have to start at 8.0.0 or can I go straight to 8.7.1?

Thanks again

8.7.1 should be the better choice here.

Not working I can see the 8.7.1 Jar in the dependencies folder and still get the following error

This sounds like a configuration error, with a missing plugin definition:
[ERROR] No plugin found for prefix 'vaadin' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Users\Papa.m2\repository), central (http://repo.maven.apache.org/maven2)]

Do you have the vaadin-maven-plugin configured in the <plugins> section correctly? You might want to create a new Vaadin 8 project from scratch and see how that is set up.
