Import file issue

[Rachana Deshpande]

IMPORTS=$(find Files/ -type d -exec echo -I '{}' \;)

echo "Generating html..."
find Files/ -name '*.proto' \
    | xargs protoc \
            ${IMPORTS} \
            --proto_path=. \
            --doc_out=. \
            --doc_opt=template.html,index.html

Gives out the already defined error.

[Rachana Deshpande]

exports/camera.proto:18:5: "camera.ENUM_VIEWID_NO_VIEW" is already defined in file "camera.proto".

Exports is a folder insider Files and it has a file camera.proto which is imported in one of other protos.
Is this because the files in imports and same as the proto files found using find statement
