Accessing Elasticsearch through JAVA API with Eclipse - maven

I'm a beginner trying to access elasticsearch through JAVA with eclipse, but after following the instructions available at this guide , eclipse is not able to import packages like org.elasticsearch.node.* and I haven't been able to continue.
This is my first time with Maven, and the configurations might be wrong.
This is my pom.xml file:
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>elasticsearch</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>${es.version}</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
I can access elasticsearch through a terminal or browser, but not with eclipse. What step I am missing?

You haven't defined es.version in your properties section. mvn install should have thrown errors because it can't download elasticsearch dependencies. I think following change to your pom would work.
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<es.version>0.90.3</es.version>
</properties>

Here is the pom.xml in my eclipse Maven project. It works. Just for you reference.

The error indicates that your XML format is incorrect and thus cannot be parsed by the XML parser. You have to check your XML carefully for opening and closing tags. For some reason your closing tag is followed by the UTF-16 Byte Order Marker.

Download/import all dependencies from Spring IO

I work for a large organization where all development tools must go through a rigorous certification process and security assessment. I want to have Spring IO Brussels SR2 certified, along with Apache Maven.
I'd like to provide them with a ZIP file containing all JARs (dependencies and transitive dependencies) of the Spring IO platform so they can do the security assessment on it.
Being a new Maven user, I've created a new Maven project in Eclipse, and simple added this in 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 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>my.company</groupId>
<artifactId>MySpringApp</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>MySpringApp Maven Webapp</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>io.spring.platform</groupId>
<artifactId>platform-bom</artifactId>
<version>Brussels-SR2</version>
<type>pom</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<finalName>MySpringApp</finalName>
</build>
</project>
The project compiles and packages correctly, but it's not importing/adding any JARs to the packaged WAR file. I've also tried to change the scope to compile.
Is it possible? Is it because it's a bill of material?
Thank you
According to the Website you have to enable the dependency-tree using
<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 http://maven.apache.org/maven-v4_0_0.xsd">

<packaging>war</packaging>

<url>http://maven.apache.org</url>
<dependencyManagement>
<dependencies>

Eclipse and Maven are designed to be able to work alone, a bit of experiences is required to let them work together, often a cleanup using Update Project ... (project-rightclick/maven) is required
I ended up downloading the dependency versions list into a CSV file, then loop through it in a simple Java class, outputting the results in a tag manually. Then, I was able to copy/paste all those tags into my pom.xml file and then get all those dependencies resolved by Maven.
Finally, I have taken the content of /target/WEB-INF/lib.

Add a common module for methods to be used by my client / server in Maven

I wanted to create a "Common" module in order to store my common methods in it for my Client and Server to use. To do so I simply created the module, and added the following to my sub-modules poms:
<dependency>
<groupId>com.christopher.kade</groupId>
<artifactId>common</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
Additionally, I don't want my common module to generate a .jar file, I just want my other modules to access its content, so here is its pom:
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<parent>
<artifactId>jcoinche</artifactId>
<groupId>com.christopher.kade</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>common</artifactId>
<packaging>jar</packaging>
<version>1.0-SNAPSHOT</version>
<name>common</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
What should I change in order to make this build work? So far it builds 3 .jars and I can't access my common methods in my client or server module.
