New issue 315 by gerd94...@gmail.com: erroneous duplicate definition error
if imported file in subdirectory
http://code.google.com/p/protobuf/issues/detail?id=315

What steps will reproduce the problem?
Create "foo.proto" containing:
import "bar.proto";

Create "x/bar.proto" containing:
message bar {
optional int32 x = 1;
}

Try to compile:
protoc --python_out=. -I. -Ix foo.proto x/bar.proto

What is the expected output? What do you see instead?
Compilation shall succeed, just like it does if "x/bar.proto"
is "bar.proto" instead.
It also succeeds if "foo.proto" contains:
import "x/bar.proto"
instead.

What version of the product are you using? On what operating system?
2.3.0 and 2.4.1
Linux and MacOS

Please provide any additional information below.

Attachments:
foo.proto 20 bytes
bar.proto 40 bytes

The error message the compiler produces is:

% protoc --python_out=. -I. -Ix foo.proto
x/bar.proto
gerd@dhcp-171-71-136-245:~/tmp/x
x/bar.proto:2:18: "bar.x" is already defined in file "bar.proto".
x/bar.proto:1:9: "bar" is already defined in file "bar.proto".

To protocol compiler "bar.proto" and "x/bar.proto" are two proto files
although they are pointed at the same physical file.
Using 'import "x/bar.proto"' is the right fix.

When I use protoc to generate /nested_extension.proto from source(version
2.5.0), I get the error message:
exec]
protobuf/java/src/test/java/com/google/protobuf/non_nested_extension.proto:39:9: "protobuf_unittest.MessageToBeExtended"
is already defined in file "com/google/protobuf/non_nested_extension.proto".

[exec]
protobuf/java/src/test/java/com/google/protobuf/non_nested_extension.proto:46:8: "protobuf_unittest.MessageToBeExtended"
seems to be defined in "com/google/protobuf/non_nested_extension.proto",
which is not imported
by "protobuf/java/src/test/java/com/google/protobuf/non_nested_extension.proto".
To use it here, please add the necessary import

How can I fix it?
