Jenkins管道，如何将工件从先前的版本复制到当前的版本? [英] Jenkins pipeline, how can I copy artifact from previous build to current build?

问题描述

在Jenkins Pipeline中，如何将工件从先前的版本复制到当前的版本? 即使以前的构建失败，我也想这样做.

In Jenkins Pipeline, how can I copy the artifacts from a previous build to the current build? I want to do this even if the previous build failed.

推荐答案

Stuart Rowe 也向我推荐了我查看了复制工件插件的管道创作Sig Gitter频道还给了我一些示例要使用的詹金斯管道语法.

Stuart Rowe also recommended to me on the Pipeline Authoring Sig Gitter channel that I look at the Copy Artifact Plugin, but also gave me some sample Jenkins Pipeline syntax to use.

根据他的建议，我想到了这个更完整的Pipeline示例 它将工件从先前的版本复制到当前的版本， 以前的构建是成功还是失败.

Based on the advice that he gave, I came up with this fuller Pipeline example which copies the artifacts from the previous build into the current build, whether the previous build succeeded or failed.

pipeline {
    agent any;

    stages {
        stage("Zeroth stage") {
            steps {
                script {
                    if (currentBuild.previousBuild) {
                        try {
                            copyArtifacts(projectName: currentBuild.projectName,
                                          selector: specific("${currentBuild.previousBuild.number}"))
                            def previousFile = readFile(file: "usefulfile.txt")
                            echo("The current build is ${currentBuild.number}")
                            echo("The previous build artifact was: ${previousFile}")
                        } catch(err) {
                            // ignore error
                        }
                    }
                }
            }
        }

        stage("First stage") {
            steps {
                echo("Hello")
                writeFile(file: "usefulfile.txt", text: "This file ${env.BUILD_NUMBER} is useful, need to archive it.")
                archiveArtifacts(artifacts: 'usefulfile.txt')
            }
        }

        stage("Error") {
            steps {
                error("Failed")
            }
        }
    }
}
