基于Jenkins Pipeline Artifactory插件，如何检查包是否已上传至Artifactory？

Absolutely! You have a couple of reliable ways to verify if a package is already uploaded to Artifactory when using the Jenkins Pipeline Artifactory plugin. Below are two common, practical approaches tailored for pipeline execution:

1. Using the Artifactory Pipeline Plugin's Built-in Methods #

This is the most streamlined approach since it leverages the plugin's native integration with your Jenkins Artifactory configuration:

• First, define your Artifactory server instance (this assumes you've already set up an Artifactory server in Jenkins via Manage Jenkins → Configure System → Artifactory):

  def artifactoryServer = Artifactory.server('YOUR_ARTIFACTORY_SERVER_ID')
  

• Construct the full path to your target package in Artifactory. This follows the format {repository-key}/{full-package-path}. For example, a JAR in the libs-release-local repo at com/example/myapp/1.2.3/myapp-1.2.3.jar would use:

  def packagePath = "libs-release-local/com/example/myapp/1.2.3/myapp-1.2.3.jar"
  

• Use the plugin's exists() method to check for the package's existence. This uses Artifactory's REST API under the hood (no full download needed, so it's efficient):

  def packageExists = artifactoryServer.exists(packagePath)
  

• Use the boolean result to control your pipeline flow:

  if (packageExists) {
      echo "*Package already exists in Artifactory. Skipping upload step.*"
      // Add custom logic here: skip upload, send a notification, etc.
  } else {
      echo "*Package not found. Proceeding with upload.*"
      // Your upload logic (e.g., using `artifactoryUpload`) goes here
  }
  

2. Directly Calling Artifactory REST API (Alternative) #

If you want more control over the request or need to retrieve additional metadata, you can send a HEAD request to Artifactory's storage API:

• First, gather your Artifactory details and credentials (retrieve credentials from Jenkins' credential store to avoid hardcoding):

  def artifactoryUrl = "https://your-artifactory-instance.com/artifactory"
  def creds = credentials('YOUR_ARTIFACTORY_CREDENTIALS_ID')
  def packagePath = "libs-release-local/com/example/myapp/1.2.3/myapp-1.2.3.jar"
  def apiEndpoint = "${artifactoryUrl}/api/storage/${packagePath}"
  

• Use the httpRequest plugin (ensure it's installed in Jenkins) to send the HEAD request. Check the response code to confirm existence:

  def response = httpRequest(
      url: apiEndpoint,
      httpMode: 'HEAD',
      authentication: creds.id,
      validResponseCodes: '200,404' // Accept both success and "not found" as valid responses
  )
  
  def packageExists = response.status == 200
  
  if (packageExists) {
      echo "*Package exists at: ${apiEndpoint}*"
  } else {
      echo "*Package does not exist at: ${apiEndpoint}*"
  }
  

Key Notes #

• Replace all placeholders (like YOUR_ARTIFACTORY_SERVER_ID and package paths) with your actual values.
• The plugin's exists() method is generally preferred because it ties into your existing Jenkins Artifactory setup, reducing manual configuration.
• Ensure your Jenkins agent has network access to your Artifactory instance.
• For broader searches (e.g., checking if any version of a package exists), use the artifactory.search() method with a search specification to find matching items.
