Maven module jar missing - eclipse

Question

I've got a multi-modules maven project and I'm trying to add a module to my project. I know a lot of questions have been asked but it didn't solved my problem. When I deploy my project, the .jar of my new module is not registered whereas my others modules are working properly.
I've added the new module in the pom of my parent module in my dependency management:
<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>com.project</groupId>
<artifactId>project-parent</artifactId>
<version>1.0.33-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>base</module>
<module>mynewmodule</module>
</modules>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.project</groupId>
<artifactId>base</artifactId>
<version>${project.version}</version>
</dependency>
<dependency>
<groupId>com.project</groupId>
<artifactId>mynewmodule</artifactId>
<version>${project.version}</version>
</dependency>
</dependencies>
</dependencyManagement>
</project>
About the pom of the new module, I've specified the packaging to jar:
<?xml version="1.0" encoding="UTF-8"?>
<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>
<parent>
<groupId>com.project</groupId>
<artifactId>project-parent</artifactId>
<version>1.0.33-SNAPSHOT</version>
</parent>
<artifactId>mynewmodule</artifactId>
<packaging>jar</packaging>
<dependencies>
<dependency>
<groupId>com.project</groupId>
<artifactId>base</artifactId>
</dependency>
</dependencies>
</project>
I've also done a maven build project.
I don't understand then why when I deploy my project with Jenkins, the jar of my new module is missing. Have I missed something?
