Error when Upgrading Vaadin from 7.3.3 to 7.4.x

I am not exactly sure what I am doing wrong here. My goal is to update Vaadin from 7.3.3 to 7.4.7, but when I try I am getting strange errors while packaging the project.

I am using IntelliJ for this, so what I tried was simply going into the POM and changing the version number. I then do a clean, followed by a package, but I get the following errors when trying:

Staying 7.3.x doesn’t. I have tried deleting my .m2 directory and rebuilding, but this does nothing for me.

Also, I have tried using the POM XML from a sample program I downloaded for 7.4.7, but that didn’t work either.

For reference, here’s my POM. Does anyone have any thoughts as to what I am doing wrong?
