Java应用从8升级到21时遇AWS依赖解析错误求助

将Java应用从JDK 8升级到JDK 21后，独立的AWS交互应用运行正常，但整合到待升级的大型项目时出现编译错误：

The type software.amazon.awssdk.awscore.client.builder.AwsClientBuilder cannot be resolved. It is indirectly referenced from required type software.amazon.awssdk.services.s3.S3BaseClientBuilder

开发环境：Eclipse + Maven

触发错误的代码片段：

StaticCredentialsProvider provider = StaticCredentialsProvider.create(creds);

导入语句：

import software.amazon.awssdk.auth.credentials.AwsBasicCredentials;
import software.amazon.awssdk.auth.credentials.AwsCredentials;
import software.amazon.awssdk.auth.credentials.StaticCredentialsProvider;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.s3.S3Client;

POM依赖配置：

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>s3</artifactId>
    <version>2.25.23</version>
</dependency>

module-info.java配置：

requires software.amazon.awssdk.auth;
requires software.amazon.awssdk.regions;
requires software.amazon.awssdk.services.s3;

独立应用无module-info.java文件，推测问题与构建路径或模块配置相关，但不确定具体原因。

• 添加AWS Core模块依赖：错误中提到的AwsClientBuilder属于awssdk-core模块，虽然s3依赖会间接引入该模块，但在模块化项目中需要显式声明依赖。在POM中添加：

  <dependency>
      <groupId>software.amazon.awssdk</groupId>
      <artifactId>awssdk-core</artifactId>
      <version>2.25.23</version>
  </dependency>
  

• 更新module-info.java：在模块声明中补充对核心模块的依赖：

  requires software.amazon.awssdk.auth;
  requires software.amazon.awssdk.regions;
  requires software.amazon.awssdk.services.s3;
  requires software.amazon.awssdk.core;
  

• 刷新依赖并清理项目：在Eclipse中执行Maven > Update Project（勾选强制更新快照/发布版），再执行Project > Clean重新构建项目。
• 检查模块路径：确认Eclipse构建路径中所有AWS SDK相关模块都已正确识别，无版本冲突或缺失情况。
