I am finishing up a multimodule project archetype which needs to do some
minor string transformations based on the standard archetype property
'rootArtifactId'.
For example, if rootArtifactId = "purchase-order" the requirement is to
produce a derived string assigned using a Velocity directive. One example of
this might be something like:
#set( $camelCase = $myCustomTool.capitalize(${rootArtifactId}) )
which yields $camelCase = "PurchaseOrder" from $rootArtifactId =
"purchase-order"
I already have the custom Velocity tool written and working correctly as a
standalone Java program, however I haven't found any specific information on
how to incorporate this custom Velocity tool in an archetype.
So my question is: "Is it possible to configure a custom Velocity tool in a
VelocityContext and have it available to use during the Velocity processing
part of project instantiation that occurs for archetype:generate in an
archetype?"
If the answer is yes, are there any examples of how to do this?
I searched far and wide in the forums where I did see some indications that
this idea was at least discussed, if not implemented. For example in the
following Nabble posting,
<http://www.nabble.com/-m2--Archetype-Plugin-parameters-and-templates-to966996.html#a977701>
Jason van Zyl said:
"The templates are velocity templates so you get the directives that
velocity provides and you can make your own velocity macros or tools. A tool
is simply a Java object that you drop into a velocity context so you can
really do whatever you want. I would think velocity itself would give you
enough flexibility. "
TIA!
