AmazonS3Java。lang.NoSuchFieldError：当我从AmazonS3下载文件时，允许将\u FINAL\u字段\u作为\u变体

Question

我有java。lang.NoSuchFieldError：在执行以下代码段时，允许\u FINAL\u FIELDS\u AS\u MUTATORS

S3Object object = s3Client.getObject(new GetObjectRequest(bucketName, fileName));

InputStream reader = new BufferedInputStream(object.getObjectContent());
File file = new File(filePathToDownload);      
OutputStream writer = new BufferedOutputStream(new FileOutputStream(file));
int read = -1;
while ( ( read = reader.read() ) != -1 ) {
         writer.write(read);
}

writer.flush();
writer.close();
reader.close(); 

Answer 1

最后，通过在AmazonS3初始化中提供正确的凭证和客户端配置，我解决了我的错误。谢谢你们的支持
