Timestamp Version From Mvn To Flex

How to add a build timestamp and version to a flex project

To do this you must be using maven 2.1 or later

Add in an additional property to your ant task, for example :

     <plugin>
    <executions>
       <execution>
         <configuration>
                 <tasks>
                       <ant antfile="${basedir}/build.xml" dir="${basedir}" target="flex">
                                   ....
                                    <property name="maven.build.timestamp" value="${maven.build.timestamp}"/>
                                    <property name="build.dir" location="${project.build.directory}"/>

                   ....
                                </ant>

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

in your pom, add in a formatter for the timestamp :

<project>
    <properties>
        <maven.build.timestamp.format>dd-MMM-yyyy HH:mm</maven.build.timestamp.format>
    </properties>

    ...... 
</project>

withing your ant task, include in the properties defined in step.1
note the is a ' around the string fields, so its value="'${pom.version}'" not value="${pom.version}"

    <mxmlc file="@{file}" fork="true" output="${build.dir}/${target_name.@{file}}@{outputFileSuffix}.swf">

    .......        
       <define name="CONFIG::pom_version" value="'${pom.version}'"/>
           <define name="CONFIG::build_time" value="'${maven.build.timestamp}'"/>

    .......
        </mxmlc>

the within flex use the CONFIG namespace get read the value of version and timestamp
