如何在执行期间从Jenkins控制台日志中提取信息，以便稍后在相同的构建执行中使用？

// 在Jenkinsfile中
pipeline {
    agent any
    stages {
        stage('Capture Log Info') {
            steps {
                script {
                    // 假设我们要捕获包含"Build Number"的行
                    def buildNumber = sh(script: 'grep "Build Number" console.log', returnStdout: true).trim()
                    env.BUILD_NUMBER = buildNumber
                }
            }
        }
        stage('Use Log Info') {
            steps {
                echo "The build number is ${env.BUILD_NUMBER}"
            }
        }
    }
}

pipeline {
    agent any
    stages {
        stage('Process Log') {
            steps {
                script {
                    // 读取控制台日志文件
                    def logContent = readFile('console.log')
                    
                    // 使用正则表达式提取信息
                    def matcher = (logContent =~ /Build Number: (\d+)/)
                    if (matcher.find()) {
                        def buildNumber = matcher.group(1)
                        echo "Extracted Build Number: ${buildNumber}"
                        
                        // 将信息存储为环境变量
                        env.BUILD_NUMBER = buildNumber
                    } else {
                        echo "Build Number not found in log."
                    }
                }
            }
        }
        stage('Use Extracted Info') {
            steps {
                echo "Using build number: ${env.BUILD_NUMBER}"
            }
        }
    }
}
