Azure pipeline YAML: assign variable to another variable

Question

I want to define variable version_ that consists of other my variables, like this:

but variables major, minor, versionCounter and branchPrefix aren't recognized, and this syntax is just transformed into string

I tried to use $(major) syntax, but it also didn't work.
How can I fix it?

The issue is you're declaring the variable at compile time. Try declaring it at runtime like this: $[variables.major]
