Package net.sf.antcontrib.perf
Class AntPerformanceListener
java.lang.Object
net.sf.antcontrib.perf.AntPerformanceListener
- All Implemented Interfaces:
EventListener
,org.apache.tools.ant.BuildListener
This BuildListener keeps track of the total time it takes for each target and
task to execute, then prints out the totals when the build is finished. This
can help pinpoint the areas where a build is taking a lot of time so
optimization efforts can focus where they'll do the most good. Execution times
are grouped by targets and tasks, and are sorted from fastest running to
slowest running.
Output can be saved to a file by setting a property in Ant. Set
"performance.log" to the name of a file. This can be set either on the
command line with the -D option (-Dperformance.log=/tmp/performance.log)
or in the build file itself ( ).
Developed for use with Antelope, migrated to ant-contrib Oct 2003.
