Is it possible to specify logger for ant inside build.xml?

Is it possible specify Ant l开发者_如何转开发istener/logger inside build.xml, not on a command line?

Within the buildfile it's possible to make use of the ant api and create an internal task via scriptdef.
i.e. implemented with groovy:

It's also possible to adjust the loglevel inside the buildfile, see :

It's not in the build file, but you can set the ANT_ARGS env variable to specify the logger

Take a look at the Recorder task. http://ant.apache.org/manual/Tasks/recorder.html

<target name="real-build">
   <exec dir="${basedir}" executable="${ant.command}" failonerror="true">
    <arg line="-f build-all.xml target ${ant.logger}" />
   </exec>
</target>
