Description Marc Mazas CLA 2011-03-22 12:55:16 EDT 
I have a (aggregator & parent) module : path /ProtoVirtualFoldersRamdisk, on location D:\Devs\UlisNG\projects\workspace-ulisng-conversion\prototypes\PrototypeVirtualFoldersRamdisk, with artifactid proto-virtualfolders-ramdisk

It has 2 sub-modules (on the same structure) : one is : path /ProtoTargetStandard, on location D:\Devs\UlisNG\projects\workspace-ulisng-conversion\prototypes\PrototypeVirtualFoldersRamdisk\TargetStandard, with artifactid target-standard
These sub-modules also inherit from the fisrt module.

I run the following configuration for the whole multi-module project : name PrototypeVirtualFoldersRamdisk, Base directory D:/Devs/UlisNG/projects/workspace-ulisng-conversion/prototypes/PrototypeVirtualFoldersRamdisk, Goals help:active-profiles compile

The launch fails :

It seems to me that the child module name is badly computed (base location + artifactid is used instead of location) :
shouldn't it be 
D:\Devs\UlisNG\projects\workspace-ulisng-conversion\prototypes\PrototypeVirtualFoldersRamdisk\TargetStandard
instead of
D:\Devs\UlisNG\projects\workspace-ulisng-conversion\prototypes\PrototypeVirtualFoldersRamdisk\target-standard
Comment 1 Igor Fedorenko CLA 2011-03-23 01:03:45 EDT 
Does the project build successfully from command line using Maven 3.0.2?
Comment 2 Marc Mazas CLA 2011-03-23 04:13:22 EDT 
Well I found that I misunderstood that the module names in the <module></module> definitions should be the (sub)directories and not the artifactids.
With that there is no issue.
Thanks.
