根据jigar的建议，我修复了这里遇到的第一个构建错误，这个错误与protobuf的版本有关。我还更新了pom文件中导致错误的thrift的版本号。但我仍然得到以下错误：

我也遇到了同样的问题，找到了解决办法。您需要安装protobuf2.4.1和thrift 0.7.0。我已经创建了演示文稿，其中包含了要遵循的步骤（关于如何安装旧版本）。希望这会有帮助

如错误消息所示：
protobuf安装版本与protobuf库版本不匹配
您使用了错误版本的协议缓冲区@jigarjoshi发布了一个指针，向您展示如何将其更改为正确的版本。
编辑：下面回答用户报告的新错误。
阅读错误消息并试图理解它们是很重要的。例如，这一条说：
/users/evanzamir/pig/pig jars/elephant bird/core/src/main/java/org/apache/thrift/fixtures.java:[118,69]错误：找不到符号
这意味着文件里
Fixtures.java，在第118行（字符69）中，有一个符号（例如，变量或方法名）以前没有定义（或正确导入/正确限定）。
