Azure - Virtual Application deployment overwrites root application

Question

I'm trying to create Azure deployment of three applications (App Service with Virtual Applications). The structure should be as follows:

/app-1
/app-2
/

Where the 3-rd application is contained in the root, containing some static files (index.html, Web.config).

For the goal I've created 2 release pipelines:

1. Deploying app-1 and static files to root
2. Deploying app-2

When I run the app-2 pipeline and then the app-1 & tatic files pipeline, everything works as expected. However, when the app-2 pipeline is ran last, the root (3-rd application) is purged, even that it's configured to deploy only to the corresponding virtual application.

Any ideas?

EDIT: Found a workaround. All of the Deploy Azure App Service tasks were added Additional Deployment Options - Web Deploy, Preserve files.

The same command was executed as before, however it seems to have effect.

Workaround

Change task version to 3. (There is 1 important change between 3<->4 - packageForLinux for version 3 is not alias for Package as it is in v4)

input json (it is not clear from readme what are inputs names): https://github.com/microsoft/azure-pipelines-tasks/blob/master/Tasks/AzureRmWebAppDeploymentV3/task.json

I also had the same issue during last days and I finally found workaround. Not desired one but it works at least.

For me workaround with web deploy was not working properly as my app was rewriting root with app files from old deploy. (O_o)

This issue is very similar to my issue so that's why I left here another workaround.
