We believe that using separate projects allow much more flexibility for configuring projects, especially when you have to enable AJDT, WTP and other Eclipse tools. More over, with multiple projects we can match Maven classpath to what JDT is using much better. Also note that issues wit nested projects in Subclipse been fixed in version 1.3.x, which been available for a while as dev builds and going to be released somewhere soon along with Subversion 1.5 release it is based on.

As for resources shown multiple times, please open an enhancement request in JIRA for this, it shouldn't be that difficult to add filter for this using org.eclipse.jdt.ui.javaElementFilters extension point (if anyone interested to work on that please let us know).

BTW, are you guys using flat or hierarchical presentation for the Package Explorer view?

 regards,
 Eugene

I think the answer isn't to uncheck it, because having each maven project be an eclipse project is a better line-up. However, having the eclipse maven plugin hide those modules in the parent project that are current projects in the workspace would be good. That would eliminate the duplication.

When using the "Check out as Maven project" option within Subclipse,
there is a checkbox labeled "Separate projects for modules." By default,
it's checked.  In my experience, Eclipse behaves better when this
checkbox is unchecked.  Why is this the default?  Here are the issues I
have with m2eclipse when Separate projects for modules is checked (and
I'm working with a multi-module project (nested layout)):

* Source trees show up twice in Package Explorer.
* Opening a .java file from one tree yields different behavior than
opening the source file from the other tree. Example: code completion is
disabled in one and works perfectly in the other.
* Synchronization issues in Subclipse.

All of these go away (well, the source trees are still shown twice but
they're empty) when "Separate projects for modules" is unchecked!
