标题说明一切

“mvn编译”会产生大量错误，以下是第一个错误：

[错误]$HOME/workspace/JavaExamplePBServiceCall/src/main/java/example/ServicecallPiqi。java:[13,23]错误：'；'预期

手动编译会产生100个错误，以下是第一个错误：

javac-cp$HOME/。m2/repository/com/google/protobuf/protobufjava/2.4.1/protobuf-java-2.4.1。jarservicecallpiqi。java

ServicecallPiqi.java:535: error: cannot find symbol
    public static com.google.protobuf.Parser<params> PARSER =
                                     ^
  symbol:   class Parser
  location: package com.google.protobuf

服务开始呼叫PIQI。爪哇：

package example;
// Generated by the protocol buffer compiler.  DO NOT EDIT!
// source: pb_piqi_out/servicecall.piqi.proto

public final class ServicecallPiqi {
  private ServicecallPiqi() {}
  public static void registerAllExtensions(
      com.google.protobuf.ExtensionRegistry registry) {
  }
  /**
   * Protobuf enum {@code cast_type}
   */
  public enum cast_type implements
//  ^^^^^^^^^^^^^ OFFENDING line

这是我的pom。xml:
