If a defaultValue is provided (regardless of whether or not required=true is
set or not), you will get the default value injected in the following
configurations specified for the parameter myValue:
- <myValue> </myValue>
- <myValue></myValue>
- <myValue/>
- myValue not specified in the configuration
If required=true is specified without a defaultValue specified, the same for
cases above will cause build failures because the required parameter has not
been specified.

Subject: Plugins with parameters and defaultValue
Hi,
just a question concerning the usage of default values in a mojo...
If i define a default value for a parameter in a Mojo like the following:
@Parameter( defaultValue = "${project.build.finalName}", required = true )
private String finalName;
So the question is:
Can i see the difference in the mojo code if someone in the pom file has
written:
<finalName/>
or
just omit it.
or is this not possible ?
In my opinion it's not possible to distinguish between those two cases.
Any ideas ?
Thanks in advance.
Kind regards
Karl Heinz Marbaise
