有很多方法可以做到这一点，但这里有一个方法。

pipeline {
    agent any
    stages {
        stage('Sample') {
            steps {
                script {
                    echo "Somehitng 1"
                    echo "Something 2"
                    // Read the console log
                    def consoleLog = Jenkins.getInstance().getItemByFullName(env.JOB_NAME).getBuildByNumber(Integer.parseInt(env.BUILD_NUMBER)).logFile.text
                    //Write the log to a file
                    writeFile(file: "Log_${BUILD_NUMBER}.txt", text: consoleLog, encoding: "UTF-8")
                    sh'''
                        git add *
                        git commit -m "Add console log"
                        git push
                    '''
                }
            }
        }
    }
}
