License for Vaadin Charts 3 not found

when I use 'vaadin:compile' generates an error: License for Vaadin Charts 3 not found. I use maven.

I download the license,but can't use it in maven.

Hi!

You can use the "Activate" button on the right side of directory to get the license. You can also use the checkbox on the left side to choose the version if needed.

Once you have your license you can follow this article regarding how to install the license. Both the license file in home folder and the -Dvaadin.charts.developer.license argument should work with maven

Hope this helps,
