[jira] [Closed] (MASSEMBLY-800) Substitution of variable fields
enclosed in ${...} does not work
[ https://issues.apache.org/jira/browse/MASSEMBLY-800?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Scholte closed MASSEMBLY-800.

Assignee: Robert Scholte
Resolution: Not A Problem
AFAIK nested properties are nowhere supported in Maven. Using a different set of delimiters is indeed the proper way to solve this.

> 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

> 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 {{*$\{...\}*}}.
