# #302 Update samples build workflow
- Introduce workflow to build samples independently from the main
project
- Keep building samples against the current snapshot version of the SDK.
Update composite build configuration.
- Temporarily disable "samples/kotlin-mcp-server": the multiplatform
project is broken. **It doesn't compile for me even on the main
branch**. Not working with [MCP
Instepcor](https://modelcontextprotocol.io/docs/tools/inspector),
because CORS is not configured. Deserves a separate PR to fix.
## Motivation and Context
Samples should be independently buildable

## Additional context
<!-- Add any other context, implementation notes, or design decisions
-->
* Modularize SDK: migrated client and server implementations to separate modules. Removed old configuration files and reorganized the source code structure
* add support native targets and update js/wasm configurations
* Refactor sample projects: add samples as composite builds, replace hardcoded dependencies with version catalog, remove obsolete gradle wrapper files
* Update .gitignore: exclude SWE agent directories (.claude/ and .junie/)
* Refine CodeQL workflow: update Kotlin build steps to target individual modules separately instead of building all at once
