This is a follow-up to #742. The `mcp-test`, `mcp-spring-webflux`, and `mcp-spring-webmvc` depended on `mcp` module which transitively brought in Jackson 3 dependencies. These modules are now decoupled and only depend on `mcp-core`. The test dependencies bring in Jackson 2 for the time being. This is a breaking change but it is required to allow easily exchanging Jackson2 and Jackson3 modules. Signed-off-by: Dariusz Jędrzejczyk <[email protected]>

This makes sense @chemicL. It is indeed a breaking change, but I think it's OK to do it |

Motivation and Context
This is a follow-up to #742.
The
mcp-test,mcp-spring-webflux, andmcp-spring-webmvcdepended onmcpmodule which transitively brought in Jackson 3 dependencies. These modules are now decoupled and only depend onmcp-core.The test dependencies bring in Jackson 2 for the time being.
This is a breaking change but it is required to allow easily exchanging Jackson2 and Jackson3 modules.
How Has This Been Tested?
Regular suite of tests.
Breaking Changes
Yes, the Jackson dependency is no longer implicit and has to be brought in explicitly by users or libraries building on top of these modules. Only the convenience
mcpmodule ships Jackson 3 to enable an easy getting-started experience.Types of changes
