Maven Assembly Plugin : Resources are not copied as expected

I am using maven assembly to build my java application and package it as a JAR file. The resources are located in src/main/resources and they are not copied to the created JAR file.
The POM.XML is like this:
<build>
<pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) -->
<plugins>
<!-- clean lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#clean_Lifecycle -->

Please let me know how can I fix this! I tried to use Resource tag, but it did not work.

How to override configLocation of a Maven Checkstyle Plugin

I want to override a configLocation that is originally declared in a configuration of a maven-checkstyle-plugin in the parent pom.xml.
But when I'm executing mvn clean package in the child project it's ignoring <configLocation>child-stylecheck.xml</configLocation> and uses parent-stylecheck.xml instead. The child-stylecheck.xml is located in the root of the project next to the pom.xml.
What could be wrong in my configurations?

Not able to generate classes through JAXB maven plugin

I'm new to maven, I've a xsd file and am trying to generate JAXB classes for that but the below code is not generating any classes. Below is part of my pom.xml, after adding jaxb2-maven-plugin I did maven clean and maven install and there are no classes generated. Am I missing something or have I misplaced it ? any help would be appreciated.
Update : I was able to generate classes when I ran the command mvn jaxb2:xjc , but not when I do mvn clean install. What should be done for this ?

I got the problem source.
The culprit is <argLine> parameter in tycho-surefire-plugin configuration.
If this param is present, jacoco file is not generated. I removed it and now .exec file is generated.
More info found at tycho-surefire argLine causes no jacaco.exec
