System properties and environment variables referenced in the code of the `ValueSource` do not become build configuration inputs, so any processing can be applied.
Instead, the value of the `ValueSource` is recomputed each time the build runs and only if the value changes the configuration cache is invalidated.
For example, a `ValueSource` can be used to get all environment variables with names containing the substring `JDK`:
