nicolas de loof commented on MGWT-76:
-------------------------------------

I don't like the idea of hard-coding the match beetween path and artifact. The 
plugin should always check the target POM to match the expected version, as 
this could introduce really complex issues. 

I'd prefer a "projectSearchPaths" parameter (coma separated list of path) and 
let the plugin auto-discover projects that match the dependencies. 

Pom.xml :
{noformat} 
<plugin>
    <artifactId>gwt-maven-plugin</artifactId>
    <configuration>
        <projectSearchPaths>${user.projects}<projectSearchPaths>
    <configuration>
</plugin>
{noformat} 

Developer then just have to use settings.xml to setup a property matching local 
folders. Typically, eclipse users could re-use the eclispe.workspace property 

Settings.xml
{noformat} 
   <properties>
        <user.projects>D:/myProjects</user.projects>
   <properties>
{noformat} 

or 

{noformat} 
   <properties>
        <user.projects>/home/me/myProjects</user.projects>
   <properties>
{noformat} 



> Solution for multi module builds and hosted mode

>             Project: Maven 2.x GWT Plugin
>          Issue Type: Improvement
>    Affects Versions: 1.1, 2.0
>            Reporter: Stefan Raubal
>
> The suggested improvement would ease rapid application development for multi 
> module environments:
> The sources of referenced modules should be added to the hosted mode 
> classpath instead of the JAR dependency (if the projects are referenced in a 
> reactor build).
> The totsp plugin was preparing a solution for multi module builds that share 
> the source folders directly. This sounded very promising and was discussed 
> here:
> http://code.google.com/p/gwt-maven/issues/detail?id=149
> Nicolas stated correctly in a discussion that the manual configuration step 
> used in the totsp patch has drawbacks and proposed a different solution:
> <quote>
> The use of some external XML file to setup "artifact" path as a project path 
> is not very maven-compliant, as Maven likes all the config to be in POM. Such 
> a feature could be nice but should be supported at maven-core level, not just 
> inside a plugin. 
> An better option COULD be to reuse code from maven-eclipse-plugin that scans 
> the workspace for other maven project and automagically replaces artifacts 
> reference with project references. This is a stronger approach : user don't 
> have to configure it's path in some XML (that is user dependent, so it SHOULD 
> not be stored in SVN and refered from POM) and the plugin code will check the 
> candidate project matches the expected version to avoid missconfiguration.
