Check the code you wrote in Maven to launch the ATL transformation.

There are several ways to launch an ATL transformation
including but not limited to:
- using an ATL launcher config (either via the GUI or the API)
- using an Ant script calling the am3.atl task
- using the ATL API (e.g., Java, Eclipse Monkey, Groove Monkey, ...)
To check for the kind of error you describe,
it is important to review the strategy you use
to ensure consistent use of models and metamodel references
in the ATL models map.

This can happen if, e.g., the ATL models map is inconsistent
w.r.t. the model / metamodel relationships.
Perhaps the consistency rule most often overlooked is the following:
- if the map has a model Mi (i.e., map[Ui] = Mi)
then make sure the map also includes Mi's metamodel
(i.e., there exists a uri, UUi, s.t.
map[UUi] = MMi and Mi.getMetamodel() = MMi)
