Azure DevOps set MultiLine Row parameter - azure-devops

Question

Is it possible to set the multiLine row parameter in the task.json file for a custom task?
{
"name": "Include",
"type": "multiLine",
"label": "Include",
"defaultValue": "#(\"*.sln\")",
"required": false,
"helpMarkDown": "example help"
}
I recocnize, that the only difference between a multiLine textbox and inline textbox (PowerShell Task) is the amount of rows:
The default amount of rows of a multiLine textbox is 2.
So it would be create to define the amount a rows in a multiLine control.

file for a custom task?
It's possible. Use .net core task have a textbox Path to projects:
Corresponding html see here:
Which is default rows of MultiLine type.
So I compared the source of Use .net core task and PS task here and found:
{
"name": "projects",
"type": "multiLine",
"label": "Path to project(s)",
"defaultValue": "",
"visibleRule": "command = build || command = restore || command = run || command = test || command = custom || publishWebProjects = false",
"required": false,
"helpMarkDown": "The path to the csproj file(s) to use. You can use wildcards (e.g. **/*.csproj for all .csproj files in all subfolders)."
}
and this:
{
"name": "script",
"type": "multiLine",
"label": "Script",
"visibleRule": "targetType = inline",
"required": true,
"defaultValue": "# Write your PowerShell commands here.\n\nWrite-Host \"Hello World\"\n",
"properties": {
"resizable": "true",
"rows": "10",
"maxLength": "20000"
},
"helpMarkDown": ""
}
The first script comes from dotnet task and second one comes from PS task. They both use MultiLine type.
According to the difference between these two scripts I think you can get what you want by setting the rows element in properties element. Something like this:
"properties": {
...,
"rows": "xxx",
...
}
Hope it helps and if I misunderstand anything, feel free to correct me :)
