plugin does not handle namespaces: imports are not recognized

[kanehekili]

My protos need to have a namespace, hence they have a "base" folder under protobuf, which they have to reference (using it for python). But qualified paths are not accepted.

Working Example
import "another.proto"

Failing:
import /myNamespace/another.proto

protoc is able to compile that code. Is this plugin capable of namespaces or is just my config wrong? (just the base parts)

                        </configuration>
                    </execution>
                </executions>
            </plugin>

directory structure:

protobuf
    myNamespace
        a.proto
        b.proto
        folderA
           c.proto
           d.proto
        ...
