I'm using NetBeans IDE 6.5 Beta (Build 200808111757) under Sun's JDK 1.6.0_02 on Windows XP.

I have created a new empty SQL Module type project, and noticed that although the comments in build.xml include
      pre-dist:                 called before jar building 
empty "extension" targets, that target is not in fact empty.  In addition to the
        <!-- Empty placeholder for easier customization. -->
        <!-- You can override this target in the ../build.xml file. -->
comments it also contains tasks to create the ${build.dir}/META-INF directory and calls the generate-wsdl-artifacts task.
If I were to follow the advice in build.xml and override the target, I would inadvertently break the generation...

If these steps truly need to be done before dist_se, then following the examples of the compile & test sections they
ought to be moved into a pre-pre-dist target.  That certainly makes sense for the mkdir tasks (by comparison with
pre-pre-compile which contains the mkdir for ${build.classes.dir}) though the generate-wsdl-artifacts task should
probably be moved into dist_se or given its own target.

One other observation; the SQL Module's build-impl.xml uses "pre-dist" and "post-dist" etc., while other project types
generally use "-post-dist" and "-post-dist" to hide such targets from 'ant -projecthelp' since they're not intended to
be called from outside the build script.
