Latest MCP Server Marketplace Module Fails with Missing Dependency jackson-core:2.22.0 (Mendix 11.10.0)

Hi everyone,I'm facing an issue with the latest MCP Server module from the Mendix Marketplace.EnvironmentMendix Studio Pro: 11.10.0Module: MCP Server (Latest Marketplace Version)OS: WindowsIssueAfter importing the latest MCP Server module and synchronizing dependencies, I get the following error:CE9804 Java dependency synchronization failed because one or more dependencies could not be found. Detailed error:Failed to resolve some dependencies. Missing dependencies: com.fasterxml.jackson.core:jackson-core:2.22.0 Build output:FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':copyDependencies'. > Could not resolve all files for configuration ':implementation'. > Could not find com.fasterxml.jackson.core:jackson-core:2.22.0. Required by: com.fasterxml.jackson.core:jackson-databind:2.22.0 io.modelcontextprotocol.sdk:mcp-json-jackson2:1.1.1 What I ObservedThe issue occurs only with the latest MCP Server module.When I import an older version of the MCP Server module, everything works correctly.This makes me think there may be a dependency issue in the latest release or a compatibility issue with Mendix 11.10.0.QuestionsHas anyone else encountered this issue?Is the latest MCP Server module compatible with Mendix 11.10.0?Is there a workaround for the missing jackson-core:2.22.0 dependency?Are there any additional Maven repositories or configuration changes required?Any guidance would be appreciated.Thanks!

Hi Karthick,

We encountered the same issue when testing the latest MCP Server module on an older Mendix 11 release.

The root cause appears to be a dependency-resolution problem rather than a Mendix 11.10.0 incompatibility issue. The module tries to resolve:


Plain Text



com.fasterxml.jackson.core:jackson-core:2.22.0

and Gradle fails during Java dependency synchronization because that artifact cannot be retrieved from the configured repositories.

As a workaround, we were able to resolve the issue by changing the Jackson dependency version from:


Plain Text



[2.21.2,3)

to:


Plain Text



2.21.4

After synchronizing dependencies again, the build completed successfully.

Based on my testing:

  • The issue is not specific to your project.
  • Older MCP Server module versions are not affected.
  • No additional Maven repositories were required.
  • The problem appears to be related to dependency resolution for the latest module release.

If anyone is blocked and needs to continue development immediately, pinning the dependency to 2.21.4 is currently the safest workaround until the Marketplace module is updated.

Hope this helps others who run into the same error.
