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.

Does the project build successfully from command line using Maven 3.0.2?
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.
