Hi, have you tried to clean up the artifacts in local maven repository?
seems like the pom for vaadin-bom-8.0.6 is corrupted.
Try to delete the whole C:\Users\c1277802.m2\repository\com\vaadin\vaadin-bom\8.0.6 directory and then try to build again

Hi Daniel,
seems like you have other corrupted jars in your local maven repository.
You can try to run
mvn dependency:purge-local-repository
from the project root directory to remove all project dependencies from local repository and resolve them again.
