非常抱歉之前的回答没有考虑到您需要保留withCredentials块的情况。请使用以下修改后的代码，以确保withCredentials块在脚本中保留，并且仍然可以正确执行Shell脚本：

pipeline {
    agent any
    
    stages {
        stage('Execute Script') {
            steps {
                withCredentials {
                    sh '''
                        rm -f /tmp/images_being_used.txt /tmp/images_being_used_sorted.txt

                        gcloud compute instances list --format="value[](name,zone)" | while IFS=$'\t' read gceName zone ;
                        do
                            gcloud compute disks describe ${gceName} --zone ${zone} | grep sourceImage | grep -v sourceImageId | awk -F '/' '{print $NF}' >> /tmp/images_being_used.txt
                        done

                        gcloud compute images list --filter="family = ${imageFamily}" --format="value[](name)" > /tmp/all_images_created.txt

                        cat /tmp/images_being_used.txt | sort -r | uniq > /tmp/images_being_used_sorted.txt
                        cat /tmp/all_images_created.txt | sort -r | uniq > /tmp/all_images_created_sorted.txt

                        for imageName in $(grep -Fxv -f /tmp/images_being_used_sorted.txt /tmp/all_images_created_sorted.txt | tail -n +${keepingCopies});
                        do
                            gcloud compute images delete ${imageName} --quiet
                            echo "deleted compute image: ${imageName}"
                        done
                    '''
                }
            }
        }
    }
}

在这个修改后的脚本中，withCredentials块被保留在sh命令内部，并且仍然可以使用凭证来执行Shell脚本。
