Just to give further details, here's what I've worked out as a (mostly)
general solution to this issue:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>compile</phase>
<configuration>
<tasks>
<property name="rsrc.dir"
value="${project.resources[0].directory}"/>
<property name="excludes"
value="${project.resources[0].excludes}"/>
<property name="rsrc.list.out"
value="${project.build.directory}/classes/${project.groupId}:${project.artifactId}:resourcelist.txt"/>
<fileset id="resources.list" dir="${rsrc.dir}"
excludes="${excludes}"/>
<pathconvert pathsep="${line.separator}"
property="resources.str" refid="resources.list">
<filtermapper>
<replacestring from="${rsrc.dir}" to=""/>
</filtermapper>
</pathconvert>
<echo file="${rsrc.list.out}" append="false"
message="${resources.str}"/>
<echo>Including resources found in ${rsrc.dir} in list
written to ${rsrc.list.out}</echo>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
The failings here being (a) it won't include resources in supplemental
resource directories in the outputted list (b) it writes files to
target/classes instead of a proper generated-sources directory
(<http://jira.codehaus.org/browse/MANTRUN-54> would make that possible, I
believe), and (c) it's ant ;-)
Better options welcome.
