Milos Kleint commented on MCOMPILER-80:
---------------------------------------
what old version of maven will actually be affected? meaning which one doesn't
set version numbers in super pom? 2.0.9 or older?
There is one big problem with the super-pom solution and that's embedding and
IDE usage. So we might end up with the IDE resolving the version differently
than the cmd maven being used later for building. Or the IDE somehow makes use
of the super-pom of the cmd-line maven being setup in the IDE. And then your
newly created quickstart archetype will be either 1.4 or 1.5 depending on what
cmd maven is on PATH?
In the case when we only change the default value in compiler plugin, the IDE
can figure the default value based on the version of the compiler plugin being
used.

> Issue Type: Improvement

> Priority: Minor

> Deafult source level setting for Maven compiler plugin is 1.3, as far as I
> remember. This makes no sense. 1.3 is used at this moment only in legacy
> applications. Probability of porting such legacy application to Maven 2 is
> very small. I was working with such applications - none of them used Maven.
> In fact, I don't know any application using Maven, which requires level 1.3.
> On the other hand, Maven is used exensively in new applications. Most of them
> use Java 5 features (annotations, generics...). All new applications I create
> use Maven 2 and Java 5. Every time I setup such application it makes me crazy
> that I get errors on my generics and annoations, and I have to setup manually
> the source level to 1.5. Come on, we have year 2008, not 2000! Java 5 is here
> for several years already. So why Maven compiler plugin does not use the most
> reasonable default approach, instead it still assumes we are in 2000 year? If
> someone wants to use old java version, than he can change the source level.
> By default should be 1.5.
> The default setting can be changed in never wersion of maven compiler plugin.
