Error while importing google/protobuf/descriptor.proto

[Sridhar]

Hi,

I am trying to import google/protobuf/descriptor.proto to define a field descriptor and compile my .proto to .scala files. But I get the below error:

Image.proto: Import "google/protobuf/descriptor.proto" was not found or had errors. 

Image.proto:26:12: "google.protobuf.FileDescriptorSet" is not defined.

I understand that the protoc compiler is not able to find the imported files(correct me if I am wrong here). Assuming this as the reason, is there a way to pass library options(libraryDependencies in sbt) to scalapbc?

Hi Sridhar,

Try adding this to your build.sbt:

libraryDependencies += "com.google.protobuf" % "protobuf-java" % "3.0.0-beta-2" % PB.protobufConfig

Hi Nadav,

I don't use SBT. I use the scalapb command line tool. Sorry for not being clear.

Hi Sridhar,

In that case just pass "-I path/to/folder" to the folder where descriptor.proto is.

Hi Nadav,

Sorry for the delayed response. I get the below error when I try to do that

AlignTypes.proto: File does not reside within any path specified using --proto_path

You may need to pass multiple -I flags, for each source root.
