ASP.NET Azure Web App Pipeline: "No package found with specified pattern: D:\a\1\s***.zip" Error
This error message, "No package found with specified pattern: D:\a\1\s***.zip", indicates that your ASP.NET Azure Web App build pipeline is unable to locate a deployment package in the expected location. This is a common problem that can occur for a variety of reasons.
Scenario:
You're deploying your ASP.NET application to Azure using the Azure DevOps pipeline. Your pipeline is configured to build and deploy the application, but the build step fails with the error message mentioned above.
Example Code:
trigger:
- main
pool:
vmImage: 'ubuntu-latest'
steps:
- task: NuGetCommand@2
displayName: 'Restore NuGet packages'
inputs:
restoreSolution: '$(solution)'
- task: DotNetCoreCLI@2
displayName: 'Build'
inputs:
command: 'publish'
publishWebProjects: 'true'
arguments: '--configuration $(BuildConfiguration) /p:PublishProfile=$(PublishProfile)'
projects: '$(solution)'
zipAfterPublish: 'true'
- task: AzureWebAppDeployment@4
displayName: 'Deploy to Azure Web App'
inputs:
azureSubscription: '$(azureSubscription)'
appName: '$(appName)'
package: '$(Build.ArtifactStagingDirectory)\*.zip'
Analysis and Clarification:
The error arises when the Azure DevOps pipeline cannot find a .zip file containing your built application in the specified directory ($(Build.ArtifactStagingDirectory)). Here are some common causes and solutions:
- Incorrect Package Path: Double-check that the
packageinput in yourAzureWebAppDeploymenttask correctly points to the directory and file pattern where your deployment package is created. The path should be relative to the agent's working directory. - Missing Deployment Package: Ensure your build pipeline is generating a
.zipfile containing your compiled application and its dependencies. Verify that thezipAfterPublishsetting in theDotNetCoreCLItask is enabled. - Incorrect Build Configuration: Make sure you are building the application with the correct configuration (e.g.,
Release) that matches your deployment profile. - Artifact Staging Directory: The
$(Build.ArtifactStagingDirectory)variable points to the location where artifacts are staged before deployment. Make sure your.zipfile is present in this directory. - Pipeline Cache: If you are using a cached pipeline, ensure the
.zipfile is present in the cache. You can either remove the cache or specify the correct path in yourAzureWebAppDeploymenttask. - Incorrect File Pattern: The
*.zippattern might be too broad. Verify that the.zipfile name is consistent and use a more specific pattern if needed.
Solutions:
- Verify the Build Process: Ensure that the build pipeline successfully creates a
.zipfile with your compiled application. Check your build logs for any errors. - Adjust the Deployment Task: Modify the
packageinput in yourAzureWebAppDeploymenttask to correctly point to the.zipfile. You can use the$(Build.ArtifactStagingDirectory)variable for this purpose. - Debug the Pipeline: Utilize the
Write-Hostcommand within your Azure DevOps pipeline script to print the values of relevant variables, such as$(Build.ArtifactStagingDirectory), to inspect the directory where the package is expected to be. - Review Pipeline Logs: Analyze the Azure DevOps build logs for detailed information regarding the build and deployment steps, particularly for any error messages.
Additional Value:
- It's recommended to utilize a specific
.zipfilename instead of a wildcard pattern to ensure clear identification of the deployment package. - Consider using a more robust build pipeline for managing your deployment workflow, including automated unit testing and code analysis steps.
- Remember to secure your Azure DevOps pipeline by implementing proper authentication and authorization mechanisms.
References:
By carefully reviewing these points and implementing the suggested solutions, you can effectively resolve the "No package found with specified pattern: D:\a\1\s***.zip" error and successfully deploy your ASP.NET application to Azure.
