How to deploy Azure Function (Java) via Azure Devops?

I'm trying to configure my pipeline to deploy a java function from Azure devops. Below are screenshots of my release configuration as well as a copy of the deployment logs. The release runs successfully but it does not create/deploy a function under my function app. Any reference material to help me understand how this deployment process works would be greatly appreciated.

Note: I'm able to deploy the app directly from Visual Studio Code using the "Deploy to Function App" option.

To enable your Azure Functions to be part of the deployment within Azure DevOps Pipelines release (CD), you need to set up and configure your Azure Functions app using Azure portal.

There are some steps have to be done in the configuration of your Azure Functions, and these steps are common regardless whatever languages you use to develop Azure Functions.

These are the tasks:

  1. Ensure that your function apps have met certain folder hierarchies
  2. Set up Continuous Deployment of your functions app using Azure portal, and ensure that you are using source from your Azure DevOps repo.
  3. Configure deployment options, including the deployment environment
  4. Configure the deployment credentials. Use the credentials to enable Azure DevOps to connect to your function app deployment

For more information in detail about those steps, please visit this MSFT docs on enabling continuous deployment on Azure Functions:

See you publish *.jar file to Function app, actually function app content is more than a jar file. Locally check folder functionappname/target/azure-functions/functionappname, after mvn build on Azure DevOps, same artifacts there are supposed to be published.

Here's an exhaustive tutorial of deploying java function in Azure DevOps.

To conclude, several steps in build and release pipeline.

  1. Choose Maven task, nothing special.
  2. Copy File task, set Content to **/azure-functions/** as mentioned above.
  3. Add Archive task, set Root folder or file to archive to $(build.artifactstagingdirectory)/target/azure-functions/<yourfunctionappname>, we can add variable for functionappname as suggested. And remember to uncheck Prepend root folder name to archive path.
  4. Publish Artifact, set Path to publish to $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip.
  5. Tutorial adds release step directly in build pipeline for simplicity, to work with release pipeline, adding one default Azure app service deploy task is enough, nothing to set except basic info like app name and so on. In 4.* Preview task, the default deployment method is Run from package, we can choose other method like the tutorial says.
