Description:
It's a behavior that appears when using maven with -X property in an unherited
project, I can't know if it's a real problem or only a bad log.
1) Make a project
2) In it's project.properties, put a property that uses an undefined property, as an
exemple
my.foo.property=${undefined.property}
3) Execute a maven goal : all goes well
4) Make a new project inheriting this one
5) Call maven in debug mode, in the log I have a :
####

with no detail about the expression that causes the problem
In MavenUtils, the line says :
String literalValue = (String) value;
and (after a quick look) the /value/ (it's the value of ${undefined.property}), in
this case is not a String but a
[EMAIL PROTECTED]:undefined.property]
It sounds like in this (inherited) case the property value is not evaluated as it
should be.
I don't know if it's a real problem or simply a log issue, but if it's simply a log
problem it should be removed or the log should be cleaner.
