Eclipse update vaadin version

I can’t update vaadin version throw plugin in eclipse.
Please see attachment.
Does anybody know what i can do?
i can update in ivy, but folder web-inf/lib not updated.
ps: In new project dialog 7.6.7 version is avaliable.

I hope you already fixed this, but if you didn’t:

If you are using Ivy, the web-inf library should be empty (because you are using automatic dependency management). If you have a vaadin jar in the lib folder AND through Ivy, it will lead to problems. Updating the version number in Ivy should be enough to get new JAR files to the classpath.
