Dominick More reopened MNG-2886:
--------------------------------


This case is not fixed it is rejected. Since neither ANT (no ANT doesn't 
dynamically include projects either I had to write custom beanshell scripts) 
nor Maven can provide a system that I can use,  I will have to write my own 
build system. So much for open source...

> Dynamically includes <module> dependencies if subfolder is available

> We would like to use Maven to build our multi-project using the <modules/> 
> construct in a top level pom file. The project contains common libraries and 
> war files. Since the war files are not dependent on each other, developers 
> are used to exclude all other war project directories out of their SCM load 
> configurations to reduce update time. Currently we have implemented ANT in 
> such a way that if a project directory is not available at build time it will 
> excluded from the build configuration. Since the sub-module pom contains the 
> <dependency/> reference to a sibling build configuration anyway the build 
> will fail if the dependency cannot be found.
> Currently if a module is defined for which no project exists you get the 
> following error:
> E:\Temp\Maven\AXN>mvn install
> [INFO] Scanning for projects...
> [INFO] 
> ------------------------------------------------------------------------
> [ERROR] FATAL ERROR
> [INFO] 
> ------------------------------------------------------------------------
> [INFO] Error building POM (may not be this project's POM).
> Project ID: unknown
> Reason: Could not find the model file 'E:\Temp\Maven\AXN\xyz\pom.xml'.
> ...
> On further investigation I located the source of the exception is being 
> thrown in the method org.apache.maven.DefaultMaven::collectProjects where the 
> modules list added at line 496:
> modulesFiles.add( moduleFile );
> The following change would do the trick...
> if( moduleFile.isFile()) {
>   modulesFiles.add( moduleFile );
> }
