Config-files as templates

[Erik Drolshammer <dr...@idi.ntnu.no>]

Hi!
I have a M2 project where we utilize two template files. Ie., two copy 
statements is necessary before the project will build:

cp log4j.properterties.tmpl log4j.properties
cp profiles.xml.tmpl profiles.xml


As far as I have learned, the "good" solution is to not use .tmpl and 
just put the files in subversion. We don't want this solution, because 
the developers sometimes (too often) commit their modified versions by 
accident.


Is it possible to do a

if (!filesExist) {
   cp log4j.properterties.tmpl log4j.properties
   cp profiles.xml.tmpl profiles.xml
}

from a maven-plugin?

Please recommend plugin(s) that support this kind of functionality.


My goal is to again allow the project to build successfully directly 
from a svn-checkout.

Yes, it is, with antrun:

   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-antrun-plugin</artifactId>
   <executions>
     <execution>
       <phase>validate</phase>
       <goals>
         <goal>run</goal>
       </goals>
       <configuration>
         <tasks>
           <!-- Overwrite defaults to false, so if the files already 	 
   exists they will not be overwritten -->
           <copy file="profiles.xml.tmpl" tofile="profiles.xml"/>
           <copy file="src/main/resources/log4j.properties.tmpl" 
tofile="src/main/resources/log4j.properties"/> 

         </tasks>
       </configuration>
     </execution>
   </executions>
</plugin>
