Compiling a proto that uses a vendored descriptor.proto

Catching up.
Do you mean that if Wire generates google/protobuf/descriptor.proto, it won't generate FileDescriptorProto that you need?

Hi @oldergod - there are two cases I tried. One is with the exact protos linked. Then it doesn't compile at all with the above error message.

If I change this import to google/protobuf/descriptor.proto

https://github.com/google/protobuf.dart/blob/master/protoc_plugin/protos/plugin.proto#L55

And remove descriptor.proto from that folder, the compilation succeeds, but naturally it didn't generate FileDescriptorProto since it wasn't part of the build.

Wire doesn't generate FileDescriptorProto. But there is a way to get it by using the https://github.com/square/wire/blob/master/wire-schema/src/commonMain/kotlin/com/squareup/wire/schema/internal/SchemaEncoder.kt

Look at the tests to see how it can be done https://github.com/square/wire/blob/master/wire-schema/src/jvmTest/kotlin/com/squareup/wire/schema/internal/SchemaEncoderTest.kt

Note that some things are not supported as described in SchemaEncoder's doc.
