java.lang.NoClassDefFoundError for CommandResolverFactory

I'm trying to test out the vert.x shell, but am having trouble getting it started. When I run the command
vertx run -conf '{"telnetOptions":{"port":5000}}' maven:io.vertx:vertx-shell:3.6.2

I get the following stack trace

Failed in deploying verticle

I'm running

java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

And Vert.x version 3.6.2 in the CLI on Windows 10 Pro.

Is there something I'm missing?

Start with the reported vertx run -conf '{"telnetOptions":{"port":5000}}' maven:io.vertx:vertx-shell:3.6.2 command and the ShellServiceImpl.start stack-trace entry. Investigate how the Vert.x shell CLI resolves the CommandResolverFactory dependency and compare it with the 3.6.2 artifact contents. Done means the command starts without the reported NoClassDefFoundError.
