java.lang.NoSuchMethodError: com.google.api.services.bigquery.model.JobConfigurationQuery.getConnectionProperties()Ljava/util/List;

Question

我对 com.google.api.services 有一些问题。 我正在使用这个版本“BigQuery API 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

确实不存在“getConnectionProperties()”方法......这是完整的错误：

Exception in thread "main" java.lang.NoSuchMethodError: com.google.api.services.bigquery.model.JobConfigurationQuery.getConnectionProperties()Ljava/util/List; at com.google.cloud.bigquery.QueryJobConfiguration$Builder.(QueryJobConfiguration.java:250) at com.google.cloud.bigquery.QueryJobConfiguration$Builder.(QueryJobConfiguration.java:95) at com.google.cloud.bigquery.QueryJobConfiguration .fromPb(QueryJobConfiguration.java:1060) at com.google.cloud.bigquery.JobConfiguration.fromPb(JobConfiguration.java:128) at com.google.cloud.bigquery.JobInfo$BuilderImpl.(JobInfo.java:158) at com .google.cloud.bigquery.Job.fromPb(Job.java:497) at com.google.cloud.bigquery.BigQueryImpl.create(BigQueryImpl.java:363) at Z4D236D9A2D102C5FE6AD1 C50DA4BEC50Z.google.cloud.bigquery.BigQueryImpl.create(BigQueryImpl.java:340) at bce_datahub.bigquery_template_0_1.bigquery_template.tJava_1Process(bigquery_template.java:383) at bce_datahub.bigquery_template_0_1.bigquery_template.runJobInTOS(bigquery_template.java:757) at bce_datahub .bigquery_template_0_1.bigquery_template.main(bigquery_template.java:583)

我看到了这个版本：

https://www.javadoc.io/doc/com.google.apis/google-api-services-bigquery/latest/com/google/api/services/bigquery/model/JobConfigurationQuery.html

包含这个方法，但如果我用这个版本替换它，我会得到另一个错误：

NoClassDefFoundError：com/google/api/services/bigquery/Bigquery$Builder

所以这个版本似乎没有这个 class。

我正在开发一个 Java 程序来：

1. 在 Bigquery 上执行查询
2. 在 Google 云存储上导出 BigQuery 表。

对于第 2 步，我没有问题。 这些是我正在使用的jara：

我正在使用 Talend Studio，所以我必须安装 jars: 一个一个。 这是产生问题的脚本的一部分：

Answer 1

解决。

我安装了在https://mvnrepository.com/artifact/com.google.apis/google-api-services-bigquery/v2-rev20201030-1.31.0 找到的 jar 。

我不明白为什么我从这里下载的jar https://www.javadoc.io/doc/com.google.apis/google-api-services-bigquery/latest/com/google/api/services/bigquery /model/JobConfigurationQuery.html

不起作用。

似乎他们是不同的。 但是我解决了我的问题。
