Missing Artifact Dependencies Follow

Hi there,

I'm trying to start writing a simple authentication plugin and whenever I create a new mvn archetype, I'm missing artifact dependencies.

Specifically:

Missing artifact org.jetbrains.teamcity:tests-support:jar:2017.2.4

Missing artifact org.jetbrains.teamcity:server-web-api:jar:2017.2.4

Missing artifact org.jetbrains.teamcity:server-api:jar:2017.2.4

I'm unsure as to how I can go about getting them and/or implementing them?
