java.lang.NoClassDefFoundError for CommandResolverFactory

[aianta]

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?

Got exactly same error with vert.x 3.6.8 on MacOS:

openjdk 11.0.4 2019-07-16

any news? I got the same error on Windows 10

PS > java -version
openjdk version "11.0.3" 2019-04-16 LTS
OpenJDK Runtime Environment Zulu11.31+11-CA (build 11.0.3+7-LTS)
OpenJDK 64-Bit Server VM Zulu11.31+11-CA (build 11.0.3+7-LTS, mixed mode)

PS> .\bin\vertx -version
3.8.5

[sibay]

using vertx full distribution (3.8.5) and copying
vertx-shell-3.8.5.jar
termd-core-1.1.6.jar
into the lib folder fixed the issue. all vertx run -conf '{"telnetOptions":{"port":8081}}' commands with

• maven:io.vertx:vertx-shell:3.8.5
• service:io.vertx.ext.shell
• io.vertx.ext.shell.ShellVerticle

worked fine.
My understanding of the maven service was, that it loads everything what is needed and sets the the correct classpath. Perhaps this assumption is wrong.
