问题

需要用Java从GCP Bigquery查询数据所需的依赖项。

我选择了GCP的Java客户端库，而不是REST API，来查询GCP Bigquery中的数据。我添加了一个Maven pom.xml文件，以获取所需的依赖项，如下所示：

<dependencyManagement>
    <dependencies>
        <!-- https://mvnrepository.com/artifact/com.google.cloud/libraries-bom -->
        <dependency>
            <groupId>com.google.cloud</groupId>
            <artifactId>libraries-bom</artifactId>
            <version>26.17.0</version>
            <type>pom</type>
        </dependency>
    </dependencies>
</dependencyManagement>
<dependencies>
    <dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>google-cloud-bigquery</artifactId>
        <version>2.27.1</version>
    </dependency>
</dependencies>

这将提供74个JAR文件。确实需要所有这些JAR文件吗？或者需要进行任何更正吗？

      <dependencyManagement>
        <dependencies>

            <!-- https://mvnrepository.com/artifact/com.google.cloud/libraries-bom -->
            <dependency>
                <groupId>com.google.cloud</groupId>
                <artifactId>libraries-bom</artifactId>
                <version>26.17.0</version>
                <type>pom</type>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.google.cloud</groupId>
            <artifactId>google-cloud-bigquery</artifactId>
            <version>2.27.1</version>
        </dependency>
    </dependencies>

如果在官方文档中提到的话，它必须是依赖所需的正确jar包数量，或者尝试使用BigQuery API参考文档中“开始之前”部分描述的pom内容。:

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>26.18.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

<dependencies>
  <dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-storage</artifactId>
  </dependency>
</dependencies>

如果您继续向下滚动，您将找到用于使用客户端库的IDE插件（这可能对您的用例有帮助）:

如果您使用Visual Studio Code、IntelliJ或Eclipse，可以使用以下IDE插件将客户端库添加到您的项目中:
- Cloud Code for VS Code
- Cloud Code for IntelliJ
- Cloud Tools for Eclipse

If it is in the official documentation it must be the correct numbers of jars needed for dependencies, or try this that pom content that described in the [before you begin][1] section of BigQuery API&#39;s reference.:

<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>libraries-bom</artifactId>
<version>26.18.0</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

<dependencies>
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>google-cloud-storage</artifactId>
</dependency>

If you scroll down a bit more you will find IDE plugins for using client libraries(that might be helpful to your use case):
