I am unable to pull the code from git while using Jenkins pipeline script. We have tried multiple scenarios but every time it clones from the repository

Right Now we are using GITSCM:
checkout([ $class: 'GitSCM',branches: [[name: "develop"]],

poll:true,

doGenerateSubmoduleConfigurations: false,

extensions: [[$class: 'LocalBranch', localBranch: '**']],

submoduleCfg: [],

userRemoteConfigs: [[url: "https://IDT.git", credentialsId: "abe-efg-2dfr"]]])

The script clones but it doesn't pull the latest code. Could you please advise how we can pull the latest code via GitScm in jenkins pipeline project?

Regards

Nick
