> I am trying to override some resources in a Maven site skin by placing files with the
same name into my /src/site/resources/ directory. For example, if I were to use the default
skin and want to override some file (say css/maven-theme.css), I would create a file /src/site/resources/css/maven-theme.css
in my Maven project and generate site with {{mvn site}}. However, in the generated site, the
maven-theme.css file from the skin JAR is used rather than my overriding copy.
> I was wondering whether this is actually allowed by design in Maven site. I investigated
the code and saw some interesting cases there regarding this issue.
> In [{{SiteMojo#renderLocale()}}|http://maven.apache.org/plugins/maven-site-plugin/xref/org/apache/maven/plugins/site/SiteMojo.html#151],
the site is rendered twice: first with normal resource directories and then with {{generated-site}}.
During each rendering ({{siteRenderer.render()}}), all skin resources are copied to the target
directory: see [{{DefaultSiteRenderer#copyResources()}}|http://maven.apache.org/doxia/doxia-sitetools/doxia-site-renderer/xref/org/apache/maven/doxia/siterenderer/DefaultSiteRenderer.html#728].
After copying the skin resources, the extra site resources from the {{src/site/resources}}
directory are copied, overwriting the skin resources.
> So in general, the code seems to allow overriding the skin resources with the ones in
src/site/resources. However, the double-rendering of the site results in the following steps
regarding the overridden file:
> 1. maven-theme.css is copied to /target from the skin JAR (normal rendering)
> 2. maven-theme.css is overridden from the src/site/resources (normal rendering) <-
I want this!
> 3. maven-theme.css is AGAIN copied to /target from the skin JAR (generated-site rendering)
> 4. resources from target/generated-site/resources are copied to /target/site, however
maven-theme.css is not there. (generated-site rendering)
> Therefore the 3rd step reverts my override. I could still achieve what I want by having
a build step that copies everything from src/site/resources to target/generated-site/resources,
which would ensure that my file is the last one copied, but it would be an unnecessary workaround..
> I am thinking that skin files only need to be copied once during the generation process.
This would allow overriding files nicely. The second rendering ([{{SiteMojo:191}}|http://maven.apache.org/plugins/maven-site-plugin/xref/org/apache/maven/plugins/site/SiteMojo.html#191])
of the {{generated-site}} sources should not repeat the original process.
> Would this be doable? By overriding resource files, it would be possible, for example,
to adjust images in the skin without creating and maintaining a new skin. In my case ([Reflow
Maven skin|http://andriusvelykis.github.io/reflow-maven-skin/]), I want to allow overriding
the Twitter Bootstrap files. I would package the default {{bootstrap.min.css}} with the skin,
but the users would be able to override the file with their own configuration. The [Bootstrap
customization|http://getbootstrap.com/customize/] or various available themes produce a full
bootstrap.min.css file, where it is easier to replace the package skin's version rather than
using site.css. site.css could have site-specific customisations, while the theme would be
placed in bootstrap.min.css. 
> I have attached a small Maven site project. I have added src/site/resources/css/maven-theme.css
to the resources but in the generated site, the skin's maven-theme.css is still used.
