How to Await Artifact Downloads in Jenkins Pipeline with Artifactory

When working with continuous integration and continuous deployment (CI/CD) systems like Jenkins, it's common to manage various artifacts during your builds. One of the popular tools used for artifact management is Artifactory. However, a frequent challenge arises when downloading multiple artifacts asynchronously; you might need to wait for these downloads to finish before proceeding to the next steps in your deployment process.

In this guide, we'll explore how to manage artifact downloads in Jenkins, ensuring that your pipeline only continues once all necessary files are fully downloaded and ready for use.

The Problem

You might have encountered a situation where you want to download multiple artifacts using Artifactory in Jenkins. The code you are using may work, but the artifact downloads occur asynchronously. As a result, your pipeline may try to use the downloaded artifacts before they are fully available, leading to potential issues and errors during runtime.

To further elaborate, consider the following example where you are downloading files using the rtDownload command:

Here, even though the artifacts download successfully, your pipeline does not wait for these downloads to complete, which can cause issues if you need these files in subsequent steps.

The Solution: Awaiting Downloads in Pipeline Syntax

To manage the waiting process effectively, you can modify your pipeline code to ensure it only proceeds after the downloads are complete. Here’s a step-by-step breakdown of how to implement this:

Step 1: Define Your Download Specifications

First, you'll need to create a dedicated download specification. This defines what files you want to download and where they should be placed in your workspace.

Step 2: Execute the Download Command

Next, you will call the download method and store the result for later verification.

Step 3: Check for Download Completion

After executing the download command, you need to verify if the files have indeed downloaded successfully. This can be done using the findFiles method, which checks if the required files are present. By checking the existence of files, your pipeline will wait until they are fully downloaded.

Summary

By integrating the above steps into your Jenkins pipeline, you ensure that the pipeline effectively waits for artifact downloads to finish before proceeding to subsequent tasks. This approach mitigates potential issues and ensures a smoother CI/CD process.

Conclusion

Managing artifact downloads in Jenkins, especially when using Artifactory, comes with its challenges. However, with the right pipeline syntax to handle download verification synchronously, you can enhance the reliability and efficiency of your automation processes.

Now, you can confidently implement these practices in your Jenkins setup, ensuring that all required artifacts are securely downloaded and ready for your build success.
