[mojo-user] [retrotranslator] question about using "mvn retrotranslator:translate"

[NGUYEN Cong Kinh]

Hello,

I'm using the retrotranslator plugin. In fact, I want to transform the 
result classes to Java 1.4. Here is my configuration:

   <plugin>
     <groupId>org.codehaus.mojo</groupId>
     <artifactId>retrotranslator-maven-plugin</artifactId>
     <executions>
       <execution>
           <phase>process-classes</phase>
           <goals>
               <goal>translate</goal>
           </goals>
           <configuration>
               <filesets>
                   <fileset>
                       
<directory>${project.build.outputDirectory}</directory>
                       <includes>
                           <include>**/*.class</include>
                       </includes>
                   </fileset>
               </filesets>
           </configuration>
       </execution>
     </executions>
   </plugin>

With this configuration, I can transform result classes to Java 1.4 by 
the command "mvn install" (it works). But, I want to specify that I use 
retrotranslator in my pom by using "mvn retrotranslator:translate", here 
is the error:

[INFO] [retrotranslator:translate]
[INFO] 
------------------------------------------------------------------------
[ERROR] FATAL ERROR
[INFO] 
------------------------------------------------------------------------
[INFO] No files to translate.

   at 
net.sf.retrotranslator.transformer.Retrotranslator.run(Retrotranslator.java:168)

Could anyone give me suggestions to solve my problem? If not, how I 
could configure my pom to transform the classes to Java 1.4 by using 
"mvn retrotranslator:translate" instead of "mvn install".

Thanks in advance!
Kinh
