Anybody has an idea how to do this with standard maven/tycho plugins
without changing existing files in the repository (I'm fine with a
build.properties.in -> build.properties transition that does the
replacement)?


The maven-resources-plugin should be able to do this for you.
I had looked at that before, but somehow always understood it would generate the file in the target directory. Re-Reading the docs I see one 
can freely specify the output directory, will play a bit with that.
Unfortunately it seems this does not quite work with Tycho's packaging plugin. I've added the following snippet to the pom of the feature that needs the replacement: 

 18     <build>
 19         <plugins>
 20             <plugin>
 21                 <artifactId>maven-resources-plugin</artifactId>
 22                 <version>2.6</version>
 23                 <executions>
 24                     <execution>
 25                         <id>copy-resources</id>
 26                         <!-- here the phase you need -->
 27                         <phase>generate-resources</phase>
 28                         <goals>
 29                             <goal>copy-resources</goal>
 30                         </goals>
 31                         <configuration>
 32                             <outputDirectory>${basedir}</outputDirectory>
 33                             <resources>
 34                                 <resource>
35 <directory>${basedir}/templates/</directory> 
 36                                     <includes>
37 <include>build.properties</include> 
 38                                     </includes>
 39                                     <filtering>true</filtering>
 40                                 </resource>
 41                             </resources>
 42                         </configuration>
 43                     </execution>
 44                 </executions>
 45             </plugin>
 46         </plugins>
 47     </build>
But running maven suggests that the build.properties file is not yet generated when the tycho-packaging-plugin does its check for bin.includes: 


mvn clean verify
