Hi NIcklas,
"during the import in eclipse" is probably the key factor. How did you
import in eclipse?
I don't think anybody is using the native eclipse maven support as it's too
slow to develop again
with a large project such as GeoServer.
Did you try this?
http://docs.geoserver.org/latest/en/developer/maven-guide/index.html#eclipse


Also, from the errors it seems you have something (the IDE maybe) setup to
work with
java 5, but GeoServer requires Java 8 as a minimum

Cheers
Andrea
