Specifying Pipeline resource version using variable

问题

When using Pipeline resource an error occurs when I am trying to use the value of the Version field as a variable value.

resources:
  pipelines:
  - pipeline: BuildApp
    source: BuildApp
    # version: $(appversion) <- this doesn't work
    version: 20191204.17  <- this works

Static version looks not so useful. Is it possible to specify such version for each run dynamically? For example, using variables.

回答1:

I tested and reproduced the problem you met and use parameters, template variable, template parameter or template will make no change, it keeps throwing error messages.

I think you can only use predefined variables here according to this thread: Is it possible to use a variable in the ref property of resources:repository for Azure DevOps YAML?.

Microsoft's answer: While we can’t allow variables in that field, this is an excellent use case for runtime parameters.
