[MNG-8672] Maven 4 CLI substitutes variable when single quoted

[jira-importer]

Alexis Tual opened MNG-8672 and commented

When executing this command line:

 

placeholder=foo mvn clean verify '-DsomeProp=${placeholder}'

 

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 change.

Affects: 4.0.0-rc-4

I knew that the offending change is a problem.

I've fixed the bug description to reflect what we see in our regression tests. We don't know if it's a use case or not; we can adapt our tests, but we just wanted to report this regression.

@michael-o What is the state here? Can this be fixed for the upcoming Maven 4 RC version as it's a regression?

I can't tell you. I stopped working on Maven Core more than a year ago and lost complete track.

@gnodet @cstamas any insights on this?
