Jenkins Pipeline中Windows环境批量解压嵌套Zip文件问题求助

Got it, let's fix this batch unzip issue you're facing on Windows. The core problem is that Jenkins' built-in unzip step doesn't natively support wildcard matching for multiple files—it only accepts a single, explicit file path. When you pass project_*.zip, it tries to find a file literally named that, hence the "does not exist" error.

Below are two reliable solutions tailored for Windows environments:

Option 1: Use PowerShell (Native Windows Approach) #

Windows PowerShell has built-in commands to handle file traversal and unzipping, making this a lightweight and robust choice. Here's how to integrate it into your Pipeline:

pipeline {
    agent any
    stages {
        stage('Batch Unzip Sub Zips') {
            steps {
                script {
                    def targetDir = "D:\\jenkins\\DEV\\extract\\project"
                    // Execute PowerShell to match and unzip each sub-zip
                    powershell """
                        Get-ChildItem -Path "${targetDir}\\project_*.zip" | ForEach-Object {
                            // Create an extract directory named after the zip file (without .zip suffix)
                            $extractFolder = Join-Path -Path "${targetDir}" -ChildPath $_.BaseName
                            // Create the directory if it doesn't exist
                            if (-not (Test-Path -Path $extractFolder)) {
                                New-Item -ItemType Directory -Path $extractFolder | Out-Null
                            }
                            // Unzip the file to the target directory (overwrite existing files with -Force)
                            Expand-Archive -Path $_.FullName -DestinationPath $extractFolder -Force
                        }
                    """
                }
            }
        }
    }
}

Key Notes: #

• Get-ChildItem finds all files matching the project_*.zip pattern in your target directory.
• $_.BaseName extracts the zip filename without the .zip extension, so each zip gets unzipped to a dedicated folder (mimicking your Linux reference command).
• Expand-Archive is Windows' native unzip command—no extra tools needed.

Option 2: Use Groovy to Iterate and Call Jenkins unzip Step #

If you prefer using Jenkins' built-in unzip step (instead of PowerShell), you can use Groovy to manually iterate over matching files and call unzip for each one:

pipeline {
    agent any
    stages {
        stage('Batch Unzip via Groovy') {
            steps {
                script {
                    def targetDir = new File("D:\\jenkins\\DEV\\extract\\project")
                    // Match all files starting with "project_" and ending with ".zip"
                    targetDir.eachFileMatch(~/project_.*\.zip/) { zipFile ->
                        // Create extract directory using the zip filename (without extension)
                        def extractDir = new File(targetDir, zipFile.name.take(zipFile.name.lastIndexOf('.')))
                        // Ensure the directory exists
                        extractDir.mkdirs()
                        // Call Jenkins' unzip step for each individual zip file
                        unzip zipFile: zipFile.absolutePath, dir: extractDir.absolutePath, quiet: true
                    }
                }
            }
        }
    }
}

Key Notes: #

• Groovy's eachFileMatch uses a regex pattern (~/project_.*\.zip/) to find all matching zip files.
• We explicitly pass each zip's full path to the unzip step, which avoids the wildcard issue since it's a single valid file path every time.
• extractDir.mkdirs() ensures the target folder exists before unzipping.

Why Your Original Attempt Failed #

Jenkins' unzip step's zipFile parameter does not resolve wildcards—it treats the input as a literal file name. When you passed D:\\jenkins\\DEV\\extract\\project\\project_*.zip, it looked for a file with that exact name (including the *), which doesn't exist in your directory.
