Subject [jira] [Created] (MASSEMBLY-800) Substitution of variable fields enclosed in ${...} does not work
Date Fri, 18 Mar 2016 20:43:33 GMT
Markus Helm created MASSEMBLY-800:
-------------------------------------

             Summary: Substitution of variable fields enclosed in ${...} does not work
                 Key: MASSEMBLY-800
                 URL: https://issues.apache.org/jira/browse/MASSEMBLY-800
             Project: Maven Assembly Plugin
          Issue Type: Bug
          Components: filtering
    Affects Versions: 2.6
            Reporter: Markus Helm
            Priority: Minor


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 {{$\{...\}}}.
