AWS Codebuild Gradle任务无法从S3存储桶下载

Question

我的aws Codebuild任务失败，因为无法从S3存储桶下载并出现以下错误消息。

The AWS Access Key Id you provided does not exist in our records. 
(Service: Amazon S3; Status Code: 403; 
Error Code: InvalidAccessKeyId; Request ID: ***; S3 Extended Request ID: *** ) 

我已经为该职位附加了政策

{
      "Effect":"Allow",
      "Action": [
        "s3:GetObject",
        "s3:GetObjectVersion",
        "s3:GetBucketVersioning"
      ],
      "Resource": "ARN: arn:aws:s3:::***",
    }

我在这里想念什么？
