                swfclipse.zip

Attached are the zipped mojo project and small test pom to reproduce the error. I am mvn installing the plugin then running with:

> Jason van Zyl asked me to raise this here so he could take a look. Not convinced it is a genuine bug...
> I am attempting to write a plugin that uses Velocity to template
> some config files. I have been developing the plugin using m2eclipse
> embedded maven runtime and it works fine. But it gives a NPE when I run 
> it in maven standalone, even with the 2.1M1 release.
> I have the following in my class:
>      /**
>       * @component
>       */
>      protected VelocityComponent velocityComponent;
> The line giving the NPE is:
>      Template template =
> velocityComponent.getEngine().getTemplate("/"+templateName+".vm");
> When running standalone the velocityComponent is initialised with a
> DefaultVelocityComponent but with a null engine, so getTemplate gives
> the NPE.
> Am struggling to understand if I'm doing this correctly and why it
> should work in maven embedder (in m2eclipse) but not standalone?
> As an aside, my class implements org.codehaus.plexus.logging.LogEnabled and running with maven embedder, the enableLogging method is called with a PlexusLoggerAdapter, but running standalone this method is not called. Can't help feeling this is related...
> I have made use of a class from the eclipse plugin project and have a dependency on other eclipse plugin support classes. This is a mojo to generate project files for FlexBuilder and I ultimately want to contribute this to the flex-mojos project.
> Thanks again.
