Java aws s3 withRegion:无法解析方法'；withRegion（com.amazonaws.regions.regions）和#x27；

尝试使用aws s3 java api创建AmazonS3ClientBuilder对象并获取错误信息

下面这个例子：

使用AWS S3 SDK（Java）：

错误：

无法解析方法“withRegion（com.amazonaws.regions.regions）”

这是一个bug还是我做错了什么

我正在使用Java 8，IntelliJ IDE和Maven for build工具

我猜问题在于您在pom文件中添加的

aws java sdk dynamodb

依赖项。这对aws-java-sdk-s3有内部依赖关系

由于依赖关系版本是

1.11.0

，因此此版本的

aws-java-sdk-s3

中可能没有

withRegion

方法（但未检查）

尝试升级到最新版本，我想你的问题应该会得到解决

---

如果您仍然看到相同的问题，请尝试发布依赖关系树结果，方法是发出命令

mvn dependency:tree

，该命令很有意思，使用您的依赖关系版本和代码片段即可。您可能有冲突的依赖关系吗？Martin-已经用完整的pom.xmlMartin更新了帖子-事实上-DynamoDB库上存在冲突的依赖关系！谢谢，谢谢你。我将DynamoDB依赖项更新为.651（最新版本），它可以编译！

AmazonS3 s3 = AmazonS3ClientBuilder.standard().withRegion(Regions.DEFAULT_REGION).build();
