我对com.google.api.services有一些问题。我正在使用这个版本“BigQueryAPI v2（修订版459）”：
https://www.javadoc.io/doc/com.google.apis/google-api-services-bigquery/v2-rev459-1.25.0/com/google/api/services/bigquery/model/jobconfigurationquery.html
实际上，方法“getconnectionproperties（）”并不存在。。。这是完全错误：
线程“main”java.lang.nosuchmethoderror中出现异常：com.google.api.services.bigquery.model.jobconfigurationquery.getconnectionproperties（）ljava/util/list；在com.google.cloud.bigquery.queryjobconfiguration$builder。java:250)在com.google.cloud.bigquery.queryjobconfiguration$builder。java:95)在com.google.cloud.bigquery.queryjobconfiguration.frompb（queryjobconfiguration。java:1060)在com.google.cloud.bigquery.jobconfiguration.frompb（作业配置。java:128)在com.google.cloud.bigquery.jobinfo$builderimpl。java:158)在com.google.cloud.bigquery.job.frompb（job。java:497)在com.google.cloud.bigquery.bigqueryimpl.create（bigqueryimpl。java:363)在com.google.cloud.bigquery.bigqueryimpl.create（bigqueryimpl。java:340)在bce\u datahub.bigquery\u template\u 0\u 1.bigquery\u template.tjava\u 1process（bigquery\u template）。java:383)在bce\u datahub.bigquery\u template\u 0\u 1.bigquery\u template.runjobintos（bigquery\u template）。java:757)在bce\u datahub.bigquery\u template\u 0\u 1.bigquery\u template.main（bigquery\u template。java:583)
我看到这个版本：
https://www.javadoc.io/doc/com.google.apis/google-api-services-bigquery/latest/com/google/api/services/bigquery/model/jobconfigurationquery.html
包含此方法，但如果将其替换为此版本，则会出现另一个错误：
noclassdeffounderror:com/google/api/services/bigquery/bigquery$builder
所以这个版本似乎没有这个类。
我正在开发一个java程序来：
对bigquery执行查询
在google云存储上导出bigquery表。
对于第二步，我没有问题。这些是我正在使用的jara：

我正在使用talend studio，所以我必须一个接一个地安装jar。这是生成问题的脚本的一部分：
