2.42.0 bug: The element XCLocalSwiftPackageReference is not supported when generating mocks with Mockingbird

[KonDouvris]

I have the following problem.

I am using Mockingbird (https://github.com/typealiased/mockingbird) for mocking.
When i am building my test target, i get an error in my generate mockingbird mocks custom shell script.

The script is the following:

set -eu

# Prevent Xcode 13 from running this script while indexing.
[[ "${ACTION}" == "indexbuild" ]] && exit 0

# Infer the derived data location from the build environment.
[[ -z "${DERIVED_DATA+x}" ]] && DERIVED_DATA="$(echo "${BUILD_ROOT}" | sed -n 's|\(.*\)/Build/.*|\1|p')"

"${DERIVED_DATA}/SourcePackages/checkouts/mockingbird/mockingbird" generate --targets "develop" "developTests"

In my project.yml i have the following target:

  developTests:
    type: bundle.unit-test
    platform: iOS
    settings:
    dependencies:
      - target: develop
      - package: Mockingbird
    sources:
      - path: appTests
      - path: MockingbirdMocks
        optional: true
    preBuildScripts:
      - path: ./bin/mockingbird.sh
        name: Generate Mockingbird Mocks
        outputFiles:
          - $(SRCROOT)/MockingbirdMocks/developMocks.generated.swift
          - $(SRCROOT)/MockingbirdMocks/developTestsMocks.generated.swift
        basedOnDependencyAnalysis: false

The problem started when update xcodegen to 2.42.0.
I am using MacOS Sequoia 15, and XCode 16.0.0

Any help would be highly appreciated.
Thanks in advance!

Hello, good afternoon. Is your problem still ongoing?

Try:

Check the Dependencies:
Make sure all dependencies are installed correctly. You can try running the following command in the terminal to ensure that Mockingbird is updated: "swift package update".

Review the Script:
Check if the path of Mockingbird in your script is correct. It should point to the correct location of the Mockingbird executable. The command in your script is: "${DERIVED_DATA}/SourcePackages/checkouts/mockingbird/mockingbird generate --targets develop developTests".

Make sure that the directory "SourcePackages/checkouts/mockingbird" actually contains the executable "mockingbird". You can use a command like "ls" to check this: "ls ${DERIVED_DATA}/SourcePackages/checkouts/mockingbird".

Check the Version of Mockingbird:
Sometimes, dependency versions can cause issues. Check if the version of Mockingbird you are using is compatible with Xcode version 16.0.0. Refer to the Mockingbird documentation to verify the supported versions.

@victorsaccucci Hello and sorry for the late reply, i was away.
Problem is still happening. Everything was working before i upgrade xcodegen to 2.42.0, so i don't know if i should start changing things regarding Mockingbird etc.

Do you have any ideas what changes in the latest xcodegen version could have introduced this issue?
