Share classes within modules in maven project

问题

firstly I'm new to maven , so sorry for the question if it's too simple :)

I have main module "main" and child modules : a , b , c , ...

What I want is to share some data which is in child module a , with child module b.

The parent pom looks like : 4.0.0

    <groupId>Parent</groupId>
    <artifactId>Parent</artifactId>
    <packaging>pom</packaging>
    <version>1.0-SNAPSHOT</version>

    <modules>
        <module>a</module>
        <module>b</module>
        <module>c</module>
    </modules>
</project>

The child I want to share looks like :

<parent>
    <artifactId>Parent</artifactId>
    <groupId>Parent</groupId>
    <version>1.0-SNAPSHOT</version>
</parent>

<modelVersion>4.0.0</modelVersion>
<artifactId>a</artifactId>
</project>

and "consumer" child looks like :

<parent>
        <artifactId>Parent</artifactId>
        <groupId>Parent</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <modelVersion>4.0.0</modelVersion>
    <artifactId>b</artifactId>

    <dependencies>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>a</artifactId>
            <version>${project.version}</version>
            <type>jar</type>
            <scope>compile</scope>
        </dependency>
    </dependencies>

I do see the jar file being added to the "External Library" (I'm using Intellij) But the jar contains only META-INF folder without the code (is it ok ?)

End of story, I cannot use Class ChildA in ChildB classes ... Any help whould be appriciated !!

The problem was that I've "btoken" maven's project stracture .... Once I've build the module as it should be by maven , works like a charm :) http://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html
