Vaadin-Maven-Plugin找不到目标

Question

I have an issue in my vaadin project. I have added an add-on that I found on the vaadin market place for making a QR Code. To make everything work I need to compile the widgetset in this add-on, but here is the problem.

When I try to use, in eclipse, the button for compiling the widgetset or directly with mvn vaadin:update-widgetset I get the following error:

[INFO] Scanning for projects...

After a bit of research it seems that some other goals are not found because now when I try to build my solution I get a similar error but with another goal:

Obviously I have missed something in my pom.xml. I'm new with maven and I can't figure out what I have missed.

So here is my pom:

Answer 1

Change <version>10.0.1</version> to something like <version>${vaadin.version}</version> . You're using the Maven plugin for Vaadin 10, which doesn't contain the same goals as the one for Vaadin 8.
