Protobuffs import from another directory

As the error message states, the file you pass on the command line needs to be in one of the --proto_paths. In your case, you have only specified one --proto_path of:

/home/project_new1/

But the file you're passing is:

/home/project_new1/settings/UserOpti‌ons.proto

Notice that the file is not in the account subdirectory; it's in settings instead.

You have two options:

• (Not recommended) Pass a second --proto_path argument to add .../settings to the path.

• (Recommended) Use the root of your source tree as the proto path. E.g.:

  protoc --proto_path=/home/project_new1/ --java_out=/home/project_new1 /home/project_new1/settings/UserOpti‌ons.proto
  

In this case, to import Account.proto, you'll need to write:

import "acco‌​unt/Account.proto";
