Package net.sf.antcontrib.perf

Class AntPerformanceListener

  • All Implemented Interfaces:
    java.util.EventListener, org.apache.tools.ant.BuildListener
    public class AntPerformanceListener
extends java.lang.Object
implements 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.
