I ran through this demo (using PowerShell). Everything was fine until I ran the line:
mvn exec:java -Dexec.mainClass=”com.blobs.quickstart.App” -Dexec.cleanupDaemonThreads=false
then I got the below exception:

Answer
As ManojReddy-MSFT suggested:
In most cases, this error occurs because of the missing plugin http://www.mojohaus.org/exec-maven-plugin/index.html
Can you verify if you have this plugin? if not, can you try with this plugin?
You can also refer to “Unknown lifecycle phase ”mvn“. You must specify a valid lifecycle phase or a goal” While Deploying the application using Azure
