Java source code has many errors after the protoc compiled

Question

My .proto file:

package com.xxxxx.cloud.module.proxy.protobuf;

option java_package = "com.xxxxx.cloud.module.proxy.protobuf";
option java_outer_classname = "ProxyHttpProtocol";

message Request{
    required string domain = 1;
    required string url = 2;
    required string body = 3;
    required int32 port = 4;
    required string method = 5;
}

some errors in java source code:

1、throw e.setUnfinishedMessage(this);//Could not find symbol
2、makeExtensionsImmutable(); //cloud not find symbol
3、ensureFieldAccessorsInitialized //cloud not find symbol
....more

I can't find any documentation to explain the reasons for these errors.

This sounds like you're missing the protobuf-java jar-file in your buildpath. You can either create it yourself by downloading the protobuf sources and running mvn package in the java directory of the download, or directly download the jar-file from the maven central repository.

Once you have the jar file, just add it to your project (either as maven dependency, or directly including it in your build path, depending on your setup).
