I have an android project that include some .proto files. After BE updates I had need to add v2 director to the project for represent version 2 of the proto files.

My proto files;

• v1/registration_update.proto
• v1/onsite_message.proto
• v1/custom_answer.proto
• v2/registration_update.proto

v1 files starts with syntax = “proto3”; package v1;

v2 files starts with syntax = “proto3”; package v2;

v1/registration_update imports v1/custom_answer.proto

v2/registration_update imports v1/custom_answer.proto

v1/onsite_message imports both v1/registration_update.proto, v2/registration_update.proto

So after that I am getting this error;

Cause: packages form a cycle:
  onsite.v1 imports onsite.v2
    v1/onsite_message.proto:
      import "v2/registration_updated.proto";
  onsite.v2 imports onsite.v1
    v2/registration_updated.proto:
      import "v1/custom_answer.proto";

Did anybody face this issue before? How can we fix it? Thanks in advance.
