> A variable field which is enclosed by {{$\{...\}}} does not get substituted during filtering. If the same variable field is not enclosed as described, the substitution works as expected.
> Before filtering:
> {code}
> #!/usr/bin/env bash
> B=${A:-${maven.default}}
> DEFAULT="${maven.default}"
> C=${A:-${DEFAULT}}
> {code}
> After filtering:
> {code}
> #!/usr/bin/env bash
> B=${A:-${maven.default}}
> DEFAULT="Hello World"
> C=${A:-${DEFAULT}}
> {code}
> The code snippet above also describes a possible workaround by defining a variable outside of {{$\{...\}}}.
