在哪里可以找到类: Apache实现的AutoValue_DynamicJdbcIO_DynamicRead？

Question

我试图用GCP数据流来实现Apache，使用谷歌提供的这个模板。

在可用的模板中，我使用的是JdbcToBigquery，这是我的用法。这些是我在pom.xml中的依赖项

在模板中，有一个类: DynamicJdbcIO.java，它帮助创建jdbc连接。可以找到这里

我在我的pom.xml文件中添加了所有与光束相关的jars。但是，在DynamicJdbcIO.java类中的代码的这一部分中，我遇到了一些错误：

  public static <T> DynamicRead<T> read() {
    return new AutoValue_DynamicJdbcIO_DynamicRead.Builder<T>().build();
  }

错误：

Cannot resolve symbol 'AutoValue_DynamicJdbcIO_DynamicRead'

我还添加了这些外部jars，以确保我拥有所有的库。

1. auto-service-1.0-rc7.jar
2. auto-value-1.7.4.jar
3. google-cloud-dataflow-java-sdk-all-2.5.0.jar
4. google-cloud-kms-1.41.1.jar
5. mssql-jdbc-9.2.0.jre8.jar
6. proto-google-cloud-kms-v1-0.88.1.jar
7. sqljdbc42-6.0.8112.jar

有谁能告诉我我在这里缺少什么吗？这是依赖型版本错配，还是AutoValue_DynamicJdbcIO_DynamicRead可用的jar文件或依赖项？

任何帮助都是非常感谢的。

你从哪里搞到这个错误的？在IDE (VS代码，IntelliJ .)中编译maven项目时会发生此错误吗？

在我看来，应该将依赖项添加到pom.xml文件中。

  <dependency>
  <groupId>com.google.auto.service</groupId>
  <artifactId>auto-service</artifactId>
  <version>${autovalue.service.version}</version>
</dependency>
    <dependency>
  <groupId>com.google.auto.value</groupId>
  <artifactId>auto-value</artifactId>
  <version>${autovalue.version}</version>
  <scope>provided</scope>
</dependency>
<dependency>
  <groupId>com.google.auto.value</groupId>
  <artifactId>auto-value-annotations</artifactId>
  <version>${autovalue.annotations.version}</version>
</dependency>

来自数据流模板的版本：

<autovalue.service.version>1.0-rc6</autovalue.service.version>   
<autovalue.annotations.version>1.7.4</autovalue.annotations.version>
<autovalue.version>1.7.4</autovalue.version>
