Multi-module web project with Spring and Maven

Question

Assume we have a few projects, each containing some web resources (e.g., html pages).

parent.pom
 +- web (war)
 +- web-plugin-1 (jar)
 +- web-plugin-2 (jar)
 ...

Let's say web is the deployable war project which depends on the known, but selectable, set of plugins.

What is a good way to setup this using Spring and maven?

1. Let the plugins be war projects and use mavens poor support for importing other war projects
2. Put all web-resource for all plugins in the web project
3. Add all web-resources to the classpath of all jar web-plugin-* dependencie and let spring read files from respective classpath?
4. Other?

I've previously come from using #1, but the copy-paste semantics of war dependencies in maven is horrible.

Answer 1

well, i use to work with point 3, definining all dependencies at parent's pom, including dependencies form modules, like that:

<parent>
 <groupId>cat.base.baseframe</groupId>
 <artifactId>projecte-pare-baseframe</artifactId>
 <version>0.0.11.a</version>
</parent>
<properties>
 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<modules>
 <module>ogc.domini</module>
 <module>ogc.logica</module>
 <module>ogc.ejb</module>
 <module>ogc.ear</module>
 <module>ogc.ui</module>
 <module>ogc.assistent</module>
</modules>
<dependencies>
 <dependency>
 <groupId>cat.base.cuesfeina</groupId>
 <artifactId>cuesfeina.domini</artifactId>
 <version>0.0.3</version>
 <scope>provided</scope>
 </dependency>
 <dependency>
 <groupId>cat.base.gea</groupId>
 <artifactId>gea.domini</artifactId>
 <version>0.0.4</version>
 <scope>provided</scope>
 </dependency>
 <dependency>
 <groupId>baseOnline.ajudes</groupId>
 <artifactId>ajudes.domini</artifactId>
 <version>0.0.1-SNAPSHOT</version>
 <scope>provided</scope>
 </dependency>
 <dependency>
 <groupId>cat.base.tramitador</groupId>
 <artifactId>tramitador.domini</artifactId>
 <version>0.0.4</version>
 <scope>provided</scope>
 </dependency>
<dependency>
 <groupId>cat.base</groupId>
 <artifactId>mme.domini</artifactId>
 <version>1.3.3</version>
 <scope>provided</scope>
 </dependency>

everything at pom's parent's it's easy to find what you need. if you need to call some service i i use to create a public jar with functions to call the service like ejb...
