Provides Amazon S3 patterns and examples using AWS SDK for Java 2.x. Use when working with S3 buckets, uploading/downloading objects, multipart uploads, presigned URLs, S3 Transfer Manager, object operations, or S3-specific configurations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AWS SDK for Java 2.x - Amazon S3 ## Overview Provides patterns for S3 operations: bucket management, object upload/download with multipart support, presigned URLs, S3 Transfer Manager, and S3-specific configurations using AWS SDK for Java 2.x. ## When to Use - Creating, listing, or deleting S3 buckets with proper configuration - Uploading or downloading objects from S3 with metadata and encryption - Working with multipart uploads for large files (>100MB) with error handling - Generating presigned URLs for temporary access to S3 objects - Copying or moving objects between S3 buckets with metadata preservation - Setting object metadata, storage classes, and access controls - Implementing S3 Transfer Manager for optimized file transfers - Integrating S3 with Spring Boot applications for cloud storage ## Quick Reference | Operation | Method | Notes | |-----------|--------|-------| | Create bucket | `createBucket()` | Wait with `waiter().waitUntilBucketExists()` | | Upload object | `putObject()` | Use `RequestBody.fromFile()` | | Download object | `getObject()` | Streams to file or memory | | Delete objects | `deleteObjects()` | Batch up to 1000 keys | …

How to install
mdr add giuseppe-trisciuoglio/developer-kit/aws-sdk-java-v2-s3@sha256:27687413af974743The line at the top of this page pins the label git:20260324.a02e282, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
