Intellij Dependency Issue - java.lang.NoClassDefFoundError

I have started using IntelliJ for my projects recently. I was trying to develop a simple maven project and got stuck into issue. I was trying to play around with kakfa-clients. Here is my dependencies
<dependencies>
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>
<version>2.5.0</version>
</dependency>
</dependencies>
I tried doing maven clean and install. I see the following error after I execute the code.
C:\KB\SDA>java -cp target/SDA-1.0-SNAPSHOT.jar org.example.code.Demo
Error: A JNI error has occurred, please check your installation and try again

However I could see the kafka-clients:2.5.0 is available in the External Libraries folder
I would like to know what could have gone wrong. Any hint would definitely help.
Java version 8
IntellJ 2020.1

Kafka-Client itself is dependent on other dependencies. Have a look here https://mvnrepository.com/artifact/org.apache.kafka/kafka-clients/2.5.0
Give a shot by including other jars in the classpath.
java -cp target/*.jar:. org.example.code.Demo

Deploy Java application using Bluemix Liberty for Java

We are trying to deploy a spring-based Java application to Bluemix using the Liberty for Java buildpack. We see the error below. We are not even using the org.apache.tiles package. The same application build works fine on a development Tomcat server.

I am using tom cat- 7, Maven version is 4.0.0
Can you please suggest me on this..
Thanks in advance

commons-logging dependency is missing. it should be in lib directory or in pom dependency declaration.
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.2</version>
</dependency>

you need check commons-logging-1.2.jar in you tomcat lib.
some dependency jar is in you project .but may not in tomcat.

It's a 404 error but I don't know why because I included all the tile libraries. Specifically, I am using struts2-core-2.1.6.jar and tiles-core-2.0.6.jar, build path is included and tiles listener is configured
<listener>
<listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class>
</listener>
More details: I am using struts-2.3.16.1 library and included
tiles-api-2.1.2.jar
tiles-compat-3.0.1.jar
tiles-core-2.0.6.jar
tiles-jsp-2.1.2.jar
tiles-servlet-3.0.1.jar
commons-beanutils-1.8.0.jar
commons-digester-2.0.jar
struts2-tiles-plugin-2.3.16.1.jar
in WEB-INF/lib

Jaxb marshalling failing with ClassNotFound Exception

I have compile my xsd doc and begun to write junit tests for my wrapper.
When I call marshal I get the stack trace below. I was surprised to have an eclipse class not found. (org.eclipse.persistence.jaxb.JAXBContextFactory)
What am I missing from my classpath? Or is there something else I am missing?
I am running eclipse indigo 3.7.2.
My classpath include the following jars:
jaxb-api.jar, jaxb-impl.jar, jaxb-xjc.jar, jaxb1impl.jar, jsr173_1.0_api.jar,
My compiler is set to java 6 compatability.

UPDATE: a manual workaround
The missing jar file is jaxb-impl.jar It is in my class path included from the jars in the ear project. If I add jaxb-impl.jar in the classpath ahead of the default classpath. it runs fine.
In other project in my same workspace I do not have this issue.

you may need the following dependencies, if you are using Maven,please refer to the following dependencies:
<dependency>
<groupId>org.eclipse.persistence</groupId>
