AWS Lambda java.lang.ClassNotFoundException: com.opencsv.exceptions.CsvException

I am getting the following error while running code on AWS lambda:
START RequestId: cd42e5ab-fbc8-4f50-8c4f-e8257525bd78 Version: $LATEST

I am working on IntelliJ created a JAR and have uploaded it to AWS Lambda using console.
This is pom.xml:

Not sure what I should do. This error only occurs when I am adding openCSV, my lambda works fine otherwise.

Upload a FAT jar or jar-with-dependencies jar to AWS & then run the lambda.
Use maven assembly or shade plugins.

Can any maven experts give me some tips on how to package a jar successfully and how to resolve this error? :)

use maven-dependency-plugin to copy the depenedencies to libs directory as metioned below. Insert this plugin before maven jar plugin under the build section

The build completes with no issues but when executing the jar it writes
no main manifest attribute, in local maven repo / my jar.
I sought aid at the docs and Baeldung too to no avail.
I seek assistance to make the jar include its dependencies and is executable at the same time.
Edit:
I updated my pom to use the jar and the dependencies plugins instead of the assembly. Here is the updated pom:

To create an executable jar, you have to use the following maven jar plugin. I provide below the code snippet.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>
your main class
</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
For more details, refer below the github link to get an idea of how to create executable/runnable jar.
https://github.com/debjava/runnableJar
As per docs, Maven Assembly Plugin for Maven is primarily intended to
allow users to aggregate the project output along with its
dependencies, modules, site documentation, and other files into a
single distributable archive.
Refer below the details of Maven Assembly plugin.
http://maven.apache.org/plugins/maven-assembly-plugin/

This is how I solved your issue:
Please ignore business logic,
since I am using MongoDB, added MongoDB driver as a dependency and able to run with java -jar command.
The end goal is same as of yours.
I am using maven-shade plug-in.
Checkout project from Github source code:
unzip, build, test
OR
1. Created a maven project
mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4
Update pom.xml with following, added mongo client code from OP and printing collection names
Execute
mvn clean package
Execute
java -jar test.jar
output I got is:

I'm likely missing something in my pom, I;m just not sure what it is. Where did I go wrong?

You most likely want to package an executable JAR. Since you are using Spring Boot you should follow chapter 71. Spring Boot Maven Plugin which explains how to do it using Spring Boot Maven Plugin.
Normally this is done by adding following build configuration to your pom.xml which be trigger during package phase.
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>2.0.4.RELEASE</version>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
As a note you are using ancient JUnit 3.8.1, you really should upgrade.
