Compile errors if a field is named 'com'

[DavidRobb]

The following proto file will not build using wire:

syntax="proto3";

message Simple {
    int32 com = 1;
}

Fine if I wasn't so lazy and called my field centre_of_mass ;-)

Generates the follwing errors:

C:\prog\ToFVe\Android\AvaCloneApp\app\build\tmp\kapt3\stubs\debug\Simple.java:6: error: int cannot be dereferenced
    @com.squareup.wire.WireField(tag = 1, adapter = "com.squareup.wire.ProtoAdapter#INT32", label = com.squareup.wire.WireField.Label.OMIT_IDENTITY)
C:\prog\ToFVe\Android\AvaCloneApp\app\build\tmp\kapt3\stubs\debug\Simple.java:6: error: an enum annotation value must be an enum constant
    @com.squareup.wire.WireField(tag = 1, adapter = "com.squareup.wire.ProtoAdapter#INT32", label = com.squareup.wire.WireField.Label.OMIT_IDENTITY)
                                                                                                                                     ^

Yikes. I think this is a JavaPoet bug.

I cannot repro with the following. The generated code compiles. WireField is imported, so something is forcing the full definition of packages somehow?

syntax = "proto3";

message Simple {
  int32 com = 1;
}

OK. I've just tried with a Basic Activity project in Android Studio and yes, the project built with the simple proto file. However, on adding Hilt dependency injection to my project I do get the error:

build.gradle project:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    ext {
        // Top-level variables used for versioning
        ext.kotlin_version = '+'
        ext.java_version = JavaVersion.VERSION_1_8
        version_navigation = "1.0.0"
        hilt_version = '2.29-alpha'
    }

    repositories {
        google()
        jcenter()
    }
    dependencies {

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
