Yes, it should. But `MaterializedField` class is in the `vector` module,
`SchemaPath` class is in the `drill-logical` module and `vector` module does
not have the dependency on the `drill-logical` module.
Replaced this code by the
`MaterializedField.create(ne.getRef().getLastSegment().getNameSegment().getPath(),
expr.getMajorType());` since simple name path is used here.
