10781080The Java SDK supports the following platforms through separate dependencies that provide platform-specific `Backend` implementations:
from line 1085
10831085* **Foundry:** `com.anthropic:anthropic-java-foundry`: Use `FoundryBackend.fromEnv()` or `FoundryBackend.builder()`.
10841086 
10851087Use `BedrockMantleBackend` for new projects; `BedrockBackend` remains for existing applications using the Bedrock `InvokeModel` API.
1088 
1089The Java SDK also supports Claude Models on Google Cloud (Anthropic managed) through `GoogleCloudBackend`, from the `com.anthropic:anthropic-java-google-cloud` dependency. This backend is in beta. Create it with `GoogleCloudBackend.builder()` or `GoogleCloudBackend.fromEnv()`. `fromEnv()` reads `ANTHROPIC_GOOGLE_CLOUD_WORKSPACE_ID`, `ANTHROPIC_GOOGLE_CLOUD_PROJECT`, and Google Application Default Credentials. See [Project, location, and workspace resolution](https://platform.claude.com/docs/en/build-with-claude/claude-models-on-google-cloud/anthropic-managed#project-location-and-workspace-resolution).
10861090 
10871091The platform artifacts are add-ons to the base `com.anthropic:anthropic-java` dependency, which provides `AnthropicOkHttpClient`, so install both. Each `Backend` implementation is passed to the client with `.backend()` on `AnthropicOkHttpClient.builder()`. Each cloud backend pulls in its respective cloud-platform SDK classes as transitive dependencies.
