Users who want to stage a file already on the local filesystem (or reachable via a custom `FileResourceService` implementation) have to first pull it into a FlowFile with `FetchFile`/`GetFile`, which is wasteful for large local files. **Changes** - Add `Resource Transfer Source` and `File Resource Service` property descriptors to `PutFile`, reusing `ResourceTransferProperties` from `nifi-resource-transfer`. - When `Resource Transfer Source = File Resource Service`, obtain a `FileResource` via `ResourceTransferUtils.getFileResource(...)` and stream its `InputStream` to the `.<filename>` temp file with `StandardCopyOption.REPLACE_EXISTING` (preserving the overwrite semantics of the original `session.exportTo(...)` call), then proceed with the existing rename / permissions / owner / group / lastModified logic. - When `Resource Transfer Source = FlowFile Content` (default) the behavior is byte-identical to today. - Add `nifi-resource-transfer` and `nifi-file-resource-service-api` (compile) and `nifi-file-resource-service` (test) to `nifi-standard-processors/pom.xml`. - Add `TestPutFile#testPutFileFromLocalFile` covering the `FileResourceService` path using `StandardFileResourceService`. **Backward compatibility** `Resource Transfer Source` defaults to `FlowFile Content`, so existing flows are unaffected. `File Resource Service` only appears in the UI when the source is set to `File Resource Service` (declared via `dependsOn`). # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [x] [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - [x] Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - [x] Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` - [x] Pull request contains [commits signed](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits) with a registered key indicating `Verified` status ### Pull Request Formatting - [x] Pull Request based on current revision of the `main` branch - [x] Pull Request refers to a feature branch with one commit containing changes # Verification Please indicate the verification steps performed prior to pull request creation. ### Build - [ ] Build completed using `./mvnw clean install -P contrib-check` - [ ] JDK 21 - [ ] JDK 25 ### Licensing - [x] New dependencies are compatible with the [Apache License 2.0](https://apache.org/licenses/LICENSE-2.0) according to the [License Policy](https://www.apache.org/legal/resolved.html) - [x] New dependencies are documented in applicable `LICENSE` and `NOTICE` files ### Documentation - [x] Documentation formatting appears as expected in rendered files -- This is an automated message from the Apache Git Service.
