检查以下代码。

def consoleLog = Jenkins.getInstance().getItemByFullName(env.JOB_NAME).getBuildByNumber(Integer.parseInt(env.BUILD_NUMBER)).logFile.text

def buildId = (consoleLog =~ 'build_id="(.*)"')[0][1]
echo "build_id: $buildId"
env.build_id = buildId

用于测试的完整管道。

pipeline {
    agent any
    stages {
        stage('Hello') {
            steps {
                script {
                    echo "Something"
                    echo "Something"
                    echo "Something"
                    echo "Something"
                    echo 'build_id="21682834"'
                    echo "Something"
                    echo "Something"
                    def consoleLog = Jenkins.getInstance().getItemByFullName(env.JOB_NAME).getBuildByNumber(Integer.parseInt(env.BUILD_NUMBER)).logFile.text

                    def buildId = (consoleLog =~ 'build_id="(.*)"')[0][1]
                    echo "build_id: $buildId"
                    env.build_id = buildId
                }
            }
        }
    }
}
