Arnaud Heritier updated MPXDOC-141:
-----------------------------------
Assign To: (was: Arnaud Heritier)
> Perform JSL transforms on xdocs *only* when they have changed
> -------------------------------------------------------------
>
> Key: MPXDOC-141
> URL: http://jira.codehaus.org/browse/MPXDOC-141
> Project: maven-xdoc-plugin
> Type: Improvement
> Versions: 1.8
> Environment: Maven 1.0.2
> Reporter: M. Sean Gilligan
> Attachments: speedup.diff
>
> Original Estimate: 4 hours
> Remaining: 4 hours
>
> Speed up the "maven site" command be eliminating tranforms of unchanged
> documents. (Patch attached.)
> There are also some ant image and stylesheet copies that seem to me should
> have overwrite="false" to eliminate redundant copies. Is there a reason for
> overwrite="true"?
> Brent Worden said on the maven dev list: "You might want to include some more
> source files for the uptodate check. The pom, the site.jsl or custom jsl,
> navigation.xml, properties files, and other files all contribute to the site
> contents."
> I'm not sure exactly what the build dependencies are (I can't really read
> jelly/jsl code that well) but I think some of the dependencies are handled
> before we get to this step, since it the performJSL tag is called for
> srcdir="${maven.gen.docs}" and srcdir="${maven.docs.src}" and the "uptodate"
> check is called inside a j:forEach loop. So, I *think* some of the
> dependencies you mentioned may have already been handled.
> I'm pretty sure that the site.jsl and navigation dependencies should be
> handled within this "uptodate" tag. I'm just not comfortable enough with the
> jelly, jsl, etc. to be comfortable trying to handle all the dependencies.
> The patch that I have does accelerate my build significantly when things
> haven't changed, but there is a risk that someone could be burned by a
> dependency not being handled and a source change not being reflected in the
> generated site.
> (Estimated work remaining assumes strong knowledge of jelly and jsl)
