Hi, Well I've worked out a what I think is a reasonable solution.
Move flex-config.xml to flex.config.template.xml and replace the flash and swf version number with tokens like so: <!-- Specifies the minimum player version that will run the compiled SWF. --> <target-player>@playerversion@</target-player> <!-- Specifies the version of the compiled SWF --> <swf-version>@swfversion@</swf-version> Add this flexconfig target to the build file: <target name="flexconfig" depends="playerglobal-setswfversion" description="Copy the flex config template to flex-config.xml and inject version numbers"> <copy file="${basedir}/flex-config.template.xml" tofile="${basedir}/flex-config.xml" overwrite="true"> <filterset> <filter token="playerversion" value="${playerglobal.version}"/> <filter token="swfversion" value="${playerglobal.swfversion}"/> </filterset> </copy> </target> <target name="playerglobal-setswfversion" description="Set the swfversion to insert into the flex config file"> <condition property="playerglobal.swfversion" value="11"> <equals arg1="${playerglobal.version}" arg2="10.2" /> </condition> <condition property="playerglobal.swfversion" value="12"> <equals arg1="${playerglobal.version}" arg2="10.3" /> </condition> <condition property="playerglobal.swfversion" value="13"> <equals arg1="${playerglobal.version}" arg2="11.0" /> </condition> <condition property="playerglobal.swfversion" value="14"> <equals arg1="${playerglobal.version}" arg2="11.1" /> </condition> </target> And finally add flexcong to depends (after prepare) in target main.
