RE: [mevenide-user] Alternative launching with mevenide

Matt,

There is a fundamental difference between Netbeans/IntelliJ/IDE
development patterns and maven patterns that I have struggled with. You
sound like your head thinks along the lines that "all my code,
regardless of sub-project, is part of my project and you should 'know'
which bits need to be recompiled". Unfortunately that's the wrong way to
think about maven projects.

Each maven project is separate. Yes, there can be nested projects but
they are all separate and self-contained (or they should be). So if you
modify code in one project then all that should matter (as far as the
'Maven way' is concerned) is that you rebuild that project, run the
tests and create a new artifact/jar. Your other projects need not be
touched - they were built using a previous version and work just fine,
don't they?

It takes a (very) long time to get into the way of thinking about
separate modules as separate projects and I'm still not all the way
there. Having said that, *I* think that the process is worthwhile for
several reasons. I *love* the dependency management in maven. I *love*
the independence from ide that it brings too. Now that Netbeans 6.0 is
proving to be such a dog in our hands, we *can* consider moving to
alternative IDEs only because we use maven under the hood. Of course,
these may not be considerations for you but they have been phenomenally
useful for us.

Later,

Andy
