Question

我已经尝试使用BigQuery API快速入门页面中提供的完整源代码从我的java eclipse运行Google Bigquery查询：

https://developers.google.com/bigquery/bigquery-api-quickstart#authorizing

代码已更改为适合我的项目，所有客户端库都已安装，运行后我不断收到此错误消息：

线程“main”中的异常java.lang.NoSuchMethodError：com.google.api.client.googleapis.services.json.AbstractGoogleJsonClient。（Lcom / google / api / client / http / HttpTransport; Lcom / google / api /客户机/ JSON / JsonFactory; Ljava /郎/字符串; Ljava /郎/字符串; LCOM /谷歌/ API /客户端/ HTTP / HttpRequestInitializer; Z）V 在com.google.api.services.bigquery.Bigquery。（Bigquery.java:108）在com.google.cloud.helix.samples.BigQuery.main（BigQuery.java:61）

我正在使用的代码是：

有人可以说出问题是什么，我该如何解决？

我建议您使用链接

中提到的相同版本的罐子

google-api-client 1.10.3-beta
google-api-services-bigquery v2-rev19-1.7.2-beta
google-oauth-client 1.10.1-beta

像1.17这样的新版本已经废除了构造函数：

AbstractGoogleJsonClient(HttpTransport,JsonFactory,String,String,HttpRequestInitializer)

他们现在使用不同的实现：AbstractGoogleJsonClient
