java.lang.ClassNotFoundException: org.mockserver.version.Version

Question

I am trying to start mock server with mockserver-netty-5.13.2 from shell, java version: 11.0.9

Rough shell code like this:

java -version
echo "start shell before java -jar line"
java -jar ./mockserver-netty-5.13.2.jar -serverPort 9090 -logLevel DEBUG &> ${DIR}/mockserver.log 

The exception thrown from java -jar ./mockserver-netty-5.13.2.jar -serverPort 9090

Exception in thread "main" java.lang.NoClassDefFoundError: org/mockserver/version/Version
    at org.mockserver.cli.Main.<clinit>(Main.java:27)
Caused by: java.lang.ClassNotFoundException: org.mockserver.version.Version

Has anyone run into this issue and resolved it ? Any help would be much appreciated !!!
