Unable to disable default java_package_prefix with managed mode

[Bryan-Lamb]

With the below buf.gen.yaml, a default java_package_prefix value of com is always set when managed mode is enabled.

Can you please add functionality to disable the default java_package_prefix from being applied?

version: v1
managed:
  enabled: true
plugins:
  - name: java
    out: gen/proto/java

Setting to an empty string unfortunately does not remove/disable the prefix

version: v1
managed:
  enabled: true
  java_package_prefix:
    default: ""
plugins:
  - name: java
    out: gen/proto/java

My workaround was to give my local module a name and make an exception for it.

# proto/buf.yaml
version: v1
name: buf.build/my/protos
breaking:
  use:
    - FILE
lint:
  use:
    - BASIC

# buf.gen.yaml
version: v1
managed:
  enabled: true
  java_package_prefix:
    default: com.pletelyirrelevant
    except:
      - buf.build/my/protos
plugins:
  - plugin: java
    out: gen/proto/java

This disabled the java_package behavior that wasn't needed because my .proto packages were already prefixed with reverse domain name. I understand that is not best practice per Files and packages, but you don't always have the luxury to change things.

Hi, I want to use the reverse domain of "xxx.co.jp". I'd like to simply generate codes with the proto package below:

• proto

syntax = "proto3";

package jp.co.xxx;

...

• buf.gen.yaml

version: v1
managed:
  enabled: true
plugins:
  - plugin: buf.build/grpc/kotlin:v1.4.1
    out: gen
  - plugin: buf.build/protocolbuffers/kotlin
    out: gen
  - plugin: buf.build/grpc/java
    out: gen

I cannot avoid the default behavior. It will generate codes with the package of com.jp.co.xxx. What can I do?

In buf.gen.yaml v2, you can now disable an option in managed mode:

version: v2
plugins:
  # ...
managed:
  disable:
    - file_option: java_package

This prevents java_package from being modified by managed mode.

You can upgrade your buf.gen.yaml by running:

buf config migrate

or

buf config migrate --buf-gen-yaml path/to/buf.gen.yaml

if your buf.gen.yaml is not at the current directory or named differently. Use the --diff flag to only display the difference between your upgraded and current file.
