在执行以下代码段时获得了java.lang.NoSuchFieldError: ALLOW_FINAL_FIELDS_AS_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();
