Karl Heinz Marbaise updated MNG-8245:
-------------------------------------
    Description: 
If I try to use one of the new life cycle phase via command line like this:
{code:java}
mvn before:clean
...
[INFO] 
--------------------------------------------------------------------------------------------------------------------------
[ERROR] No plugin found for prefix 'before' in the current project and in the 
plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the 
repositories [local (/Users/khm/.m2/repository), nexus (
{code}
That will fail (from my perspective as expected) because that's a conflict with 
the syntax for calling a goal of a plugin. That means at the moment it's not 
possible to call a thing like {{(before:|after:)$phase}} or alike...on 
command line...

 

This behaviour is already documented on 
[https://cwiki.apache.org/confluence/display/MAVEN/Dynamic+phases] 

The questions which arise: 
* Should it be possible to call things like that via CLI? That could be helpful 
for testing things out?
* Or Should we at least correctly WARN about such situations?
