Answer 1

Are you trying to upload your directory structure to s3?

Then you can try this with the CLI:

aws s3 sync . s3://mybucket

https://docs.aws.amazon.com/cli/latest/reference/s3/sync.html

You could also achieve this programatically:

TransferManager tm = new TransferManager(new ProfileCredentialsProvider());
MultipleFileUpload upload = tm.uploadDirectory(bucket, folder, new File(filePath), true);

try
{
    // Or you can block and wait for the upload to finish
    upload.waitForCompletion();
    LOGGER.debug("Upload complete.", bucket, folder);
}
catch (AmazonClientException amazonClientException)
{
    LOGGER.error("Unable to upload file, upload was aborted.", amazonClientException);
    throw amazonClientException;
}
