Unable to create a view in Eclipse using New -> Other -> Vaadin -> New > Vaadin 10+ Design

Question

I am evaluating Vaadin and I create a spring boot project with Vaadin dependency. I imported my project in Eclipse and on the folder frontend/src/views, followign the documentation https://vaadin.com/docs/latest/tools/designer/getting-started/build-your-main-view, I did : New -> Other -> Vaadin -> New > Vaadin 10+ Design -> Next. Each time I click on Next, I got the following error :

Following document, I am supposed to switch to another panel but nothing happen.

What am I doing wrong ? I am using Eclipse Version: 2023-03

thanks for your help Best regards Genevieve

Obviously, the Vaadin Designer plugin uses m2e, but works only with m2e 1.x, not with m2e 2.x because of this change that has been introduced in m2e 2.0. It seems that the Vaadin plugin has not specified an upper version range for m2e, so it can be installed even into an Eclipse IDE with m2e 2.x (which should not be possible), causing the error to occur at runtime.

See Vaadin Designer issue #2449 - Cannot start designer (Eclipse Windows)
