Alexis Tual updated MNG-8672:
-----------------------------
Description:
When executing this command line:
{code:java}
placeholder=foo mvn clean verify '-DsomeProp=${placeholder}'{code}
Then we get:
- Maven 3: {{someProp}} equals to {{${placeholder}}}
- Maven 4.0.0-rc-4-SNAPSHOT (5426073a3655278e58f8a4178faae335b1544fc0) :
{{someProp}} equals to {{foo}}
The single quote implies the variable should not be substituted, in that sense
Maven 3 seems to be the correct behavior.
It's due to this
