Errors after update to

Hi, every one.Pleas help.

Updated from 14.0.0.beta to

Java ver:1.8.0_211

** After start app console output is:**

Error:(6, 43) java: cannot find symbol
symbol: class TextFieldVariant
location: package com.vaadin.flow.component.textfield


Error:(7, 40) java: cannot find symbol
symbol: class ButtonVariant
location: package com.vaadin.flow.component.button

this is definitely a dependency collision.
Try to clean your project at least.
Do you have any explicit dependencies to old vaadin component JARs ?
Make sure you are using only platform dependencies and it should work.
