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.

As a workaround (until the Vaadin Designer plugin has been adapted for m2e 2.x), Eclipse 2022-06 can be used or m2e can be downgraded to 1.20.1 (using the update site https://download.eclipse.org/technology/m2e/releases/1.20.1/).

Hello @howlger, you're correct about m2e issue. Sadly, backward compatibility has been broken and latest Eclipse comes with the latest m2e by default.

I have updated needed API calls to the new format already and planning to release new Designer version later this week. I will keep you posted when release will be done.

Fixed in Vaadin Designer 4.6.21. Closed.
