Description

A variable field which is enclosed by ${...} does not get substituted during filtering. If the same variable field is not enclosed as described, the substitution works as expected.

Before filtering:

#!/usr/bin/env bash
B=${A:-${maven.default}}

DEFAULT="${maven.default}"
C=${A:-${DEFAULT}}

After filtering:

#!/usr/bin/env bash
B=${A:-${maven.default}}

DEFAULT="Hello World"
C=${A:-${DEFAULT}}

The code snippet above also describes a possible workaround by defining a variable outside of ${...}.
