How to run a maven project on mac

I am trying to run a simple maven project from the mac terminal.
Here is my pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>HelloWorld</artifactId>
<version>1.0</version>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
<build>
<plugins>
<plugin>
<!-- Build an executable JAR -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<!-- here we specify that we want to use the main method within the Controller class -->
<mainClass>com.helloworld.Countries</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
<dependencies>
<!-- https://mvnrepository.com/artifact/com.googlecode.json-simple/json-simple -->
<dependency>
<groupId>com.googlecode.json-simple</groupId>
<artifactId>json-simple</artifactId>
<version>1.1.1</version>
</dependency>
</dependencies>
</project>
I did maven package.
and when I try to run:
java -jar target/HelloWorld-1.0.jar
… I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/json/simple/JSONValue
Is the java.lang.NoClassDefFoundError only on macOS? I did the same project on Windows and it works fine.
Is there anyway that we can make this independent of OS?

Solution was to use Maven-shade-plugin. Here is my final POM.

Mapping is not happening when project is mavenized

I am using a EAR architecture type project with spring framework on jboss 6.1EAP, Initially, when my project was not mavenized it was working fine and all the mapping was going fine( as can see in the server logs) But as soon as I mavenize my project all the mapping which maps the controllers are gone (No Mapping at all). How to resolve this ? what I am doing wrong ?
I am using M2E plugin in eclipse

Merge Java module dependencies resources into WAR using Maven

I have a multiplatform project which has several language-specific profiles. The HTML-platform-specific module depends on an "assets-core" module and if "en" profile is enabled, an "assets-en" module resources should also be included into WAR.
Assembling WAR works just fine with an exception that if "assets-core" module contains file with the same file name as "assets-en", it is not overwritten by the file from "assets-en" module.
I tried to use maven-resource-plugin:
<build>
<resources>
<resource>
<directory>${basedir}/assets-en/src/main/resources</directory>
<includes>
<include>**/*</include>
</includes>
</resource>
</resources>
</build>
with
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<id>copy-prod-resources</id>
<phase>process-resources</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<overwrite>true</overwrite>
<outputDirectory>${basedir}/target/classes</outputDirectory>
<resources>
<resource>
<directory>${basedir}/assets-ar/src/main/resources</directory>
<includes>
<include>**/*</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
and <maven.resources.overwrite>true</maven.resources.overwrite> enabled as other threads suggests, but nothing worked.
maven-war-plugin overlays could also be the solution but I can't have resource module to be packaged with <type>war</type> because the same module is also included in Java project.
Here are the relevant parts of my pom.xmls:

OK, so I finally have found a solution. You need to get rid of dependencies to modules and copy the resources using maven-resources-plugin:

In the current .pom you are building an ear and you are giving the same ear as a warModule.
You should give a .war artefact for webmodule in the ear-plugin

EAR is packing two copies of WAR and JAR projects

My Maven EAR project packs my EAR with two copies of each of my libraries. One copy is always appended with the version (In my case 1.0-SNAPSHOT). Is there something screwed up in my POMs?
I keep getting these type of errors when i try and deploy to server:
Servlet [blah...] and Servlet [blah..] have the same url pattern: [/RegistrationService_V10].
My EAR project POM looks like this :
<?xml version="1.0" encoding="UTF-8"?>

In the maven-ear-plugin, you have to specify your ejbmodule and webmodule
<plugin>
<artifactId>maven-ear-plugin</artifactId>
<version>2.8</version>
<configuration>
<modules>
<ejbModule>
<groupId>com.huwag</groupId>

Could you give us the feedback if it works better?
