Kotlin/TeamCity environment variable to uppercase

Question

I want to pass the value stored in "%env.VAR%" to other variable in uppercase. But I'm getting %ENV.VAR% as result.

Tried:

# "%env.VAR%" = something
val var_1 = "%env.VAR%"
val var_2 = var_1.uppercase()

The code above returns:

var_2 = %ENV.VAR%

but I want it to be:

var_2 = SOMETHING

Answer 1

What I wanted was not possible. When reading teamcity environment variables in kotlin, during compilation time, they are read as literals.

That is why "%env.VAR%".uppercase() was returning %ENV.VAR%. During the execution time, the expression "%env.VAR%" is read as environment variable, and %ENV.VAR% fails to return anything.
