WorkBook = new XSSFWorkbook(inputStream) InputStream in = new BufferedInputStream(link.openStream()) īyteArrayOutputStream out = new ByteArrayOutputStream() įileOutputStream fos = new FileOutputStream("/tmp/" + fileName) InputStream objectData = object.getObjectContent() S3Object object = s3Client.getObject(new GetObjectRequest(bucketName, key)) The Java Runtime Environment (JRE) is required to run Java programs. * //AmazonS3 s3Client = new AmazonS3Client(new ProfileCredentialsProvider()) ĪmazonS3 s3Client = AmazonS3ClientBuilder.standard().build() jar file into the Minecraft Server folder.
