Tutorial: Creating a Project with IntelliJ IDEA: Error: could not transfer metadata from org.apache.maven.plugins

https://vaadin.com/docs/v8/framework/getting-started/getting-started-idea.html

i followed the Tutorial and get this error inside the IDE:

could not transfer metadata 
org.apache.maven.plugins:maven-archetype-plugin/maven-metadata.xml 
from/to central (https://repo.maven.apache.org/maven2): 
transfer failed for 
https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-archetype-plugin/maven-metadata.xml

i also wiped all my rm -rf ~/.m2 directory with the same error

workaround:

use the commandline tutorial here: https://vaadin.com/docs/v8/framework/getting-started/getting-started-maven.html

note:

after running the command line i think all artefacts are in the ~/.m2 cache and there was this error not anymore. but for new users this can be a PITA, maybe add here an info to use the command line when this error arise

Review the IntelliJ IDEA tutorial at the linked getting-started-idea.html page and compare it with the command-line guidance in getting-started-maven.html. Document the command-line workaround for the Maven metadata transfer error, and confirm that the page clearly explains what new users should do when the IDE setup fails.
