Re: best practices for modular GWT app

Hi all, currently my application is using a single module for the GWT code, but I'd like to split it in some submodules to better organize the code.
Everything is under maven and I organised the main project layout using Thomas Broyer gwt-maven-archetypes [1], so now I have a main maven project and its 3 submodules (client, shared and server): my goal is to have the client submodule that will use the new GWT-submodules, but which is the best approach?

I think I found a reasonable solution to my problem adding a maven submodule, and in the main pom.xml I just added this:

<modules>
    <module>App-client</module>
    <module>App-module-user</module>
    <module>App-shared</module>
    <module>App-server</module>
</modules>

in the "App-client" pom.xml (this is the main GWT app) I just added:

<dependency>
    <groupId>${project.groupId}</groupId>
    <artifactId> App-module-user</artifactId>
    <version>${project.version}</version>
    <type>gwt-lib</type>
</dependency>

and last this is the pom.xml file for the App-module-user:

<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>net.morettoni.test</groupId>
        <artifactId>App</artifactId>
        <version>master</version>
    </parent>

    <artifactId>App-module-user</artifactId>
    <packaging>gwt-lib</packaging>

    <prerequisites>
        <maven>${mavenVersion}</maven>

            <artifactId>App-shared</artifactId>
            <version>${project.version}</version>
        </dependency>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId> App-shared</artifactId>
            <version>${project.version}</version>
            <classifier>sources</classifier>
        </dependency>
        <dependency>
            <groupId>com.google.gwt</groupId>
            <artifactId>gwt-user</artifactId>
        </dependency>

        <!-- tests dependencies -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>net.ltgt.gwt.maven</groupId>
                <artifactId>gwt-maven-plugin</artifactId>

                <configuration>
                    <moduleName>net.morettoni.test.App.User</moduleName>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

Hope this may help others!

A special Thanks to Thomas for the FANTASTIC plugin!!!
