忽略布尔字段生成的grpc java代码

Question

我正在eclipse中使用protoc jar maven插件（3.11.4）从proto文件自动生成grpc存根。在生成代码时，我注意到proto中的my Bool数据类型字段（“proto3”）并不是生成的类的一部分。

不知道为什么只有bool数据类型字段会丢失，因为所有字符串数据类型都正确地出现在哪里。

我无法重现这个问题。这是pom.xml和原型：https://gist.github.com/sergiitk/d16891f15b4e2506848f40ebfb62a7ec

我使用了helloworld。grpc java repo中的proto示例，并添加了布尔结果=2 至<代码>HelloReply
在运行maven之后，结果是HelloReply。java具有预期的结果字段：

public static final int RESULT_FIELD_NUMBER = 2;
private boolean result_;
/**
 * <code>bool result = 2;</code>
 * @return The result.
 */
public boolean getResult() {
  return result_;
}

这是maven日志：
