[JENKINS-69389] resolveScm cannot lookup Folder credentials

The resolveScm step does not find folder credentials. The step does not fail, rather it tries to fetch sources as anonymous.

• Create a credentials at root with ID my-creds-in-root


• Create the same credentials inside a folder with ID my-creds-in-folder


• Create a Multibranch project where you have a branch with a pipeline like the following:

pipeline {

    agent any

    

    stages {

stage('test') {

    steps {

resolveScm(source: [$class: 'GitSCMSource', credentialsId: 'my-creds-in-root', id: '_', remote: 'https://github.com/privateowner/repo.git', traits: [gitBranchDiscovery()]], targets: ['main'])

resolveScm(source: [$class: 'GitSCMSource', credentialsId: 'my-creds-in-folder', id: '_', remote: 'https://github.com/privateowner/repo.git', traits: [gitBranchDiscovery()]], targets: ['main'])

    }

}

    }

}

• You should see that the first one works, the second one fails (and the git log shows that no credentials it used)

Note: This can be reproduced with different SCM Source implementation:
