The following build.xml snippet is an example of how to use the recorder to record just the <javac> task:
... <compile > <record name="log.txt" action="start"/> <javac ... <record name="log.txt" action="stop"/> <compile/> ...The following two calls to <record> set up two recorders: one to file "records-simple.log" at logging level info (the default) and one to file "ISO.log" using logging level of verbose.
... <record name="records-simple.log"/> <record name="ISO.log" loglevel="verbose"/> ...
