Peformance Task usage from custom task
Hi,
Is it possible to set the performance monitoring as described in
http://antelope.tigris.org/nonav/docs/manual/bk03ch27.html (i.e enable and
disable such data collection) from a custom ant tasks java code.
My need to enable monitoring only during the execution of the custom task
and remove it once that is executed.
Also, I am not interested to change the ant launch time parameters as this
would impact entire build completion and not ideal for our needs.
Regards,
Raja Nagendra Kumar,

Note that if your intention is to profile your own task, you can also use
any profiler you want. An ant build is a java application like an other.

You could also subclass that listener and overwrite the [task|target][Starts|Finished] by calling the build[Starts|Finished] method.
Would that help?
Or use the StopWatchTask?

Nope Jan..
On making such correction it giving error in line 188
i.e the line
StopWatch sw = ( StopWatch ) targetStats.get( be.getTarget() );
of targetFinished()..
It appears to me that AntPerformanceListener or the interface BuildListener
is not custom tag friendly..
Some of the things I see from the interface are.. they are meant for
printing the report of entire build and not between when it is added and
when it is removed..
I saw some where SubAntListener etc.. which means not sure impact of calls
antcall and ant and subant tags usage..
May be it would be nice to put AntPerformanceListener or BuildListener
towards TaskPerfListener level rather than entire build level..

AW: Peformance Task usage from custom task
Posted by Ja...@rzf.fin-nrw.de.
According to your stacktrace the NPE occurs in line 62 of the listener
Its source is available here:
http://ant-contrib.svn.sourceforge.net/viewvc/ant-contrib/ant-contrib/trunk/src/main/java/net/sf/antcontrib/perf/AntPerformanceListener.java?revision=130&view=markup
long stop_time = master.stop();
So 'master' is null.
This field is initialized in the buildStarted() method, which is invoked before your task started.
So try instead your add
AntPerformanceListener perf = new net.sf.antcontrib.perf.AntPerformanceListener();
perf.buildStarted(null); // the BuildEvent is not evaluated in that method
getProject().addBuildListener(perf);

Hi Dale,
Thank you for the pointer.
Tried this in custom ant ask getProject().addBuildListener(new
net.sf.antcontrib.perf.AntPerformanceListener());
this at the end of the build give the below exception..
java.lang.NullPointerException
at
net.sf.antcontrib.perf.AntPerformanceListener.buildFinished(AntPerfor
manceListener.java:62)
at org.apache.tools.ant.Project.fireBuildFinished(Project.java:2037)
at org.apache.tools.ant.Main.runBuild(Main.java:778)
at org.apache.tools.ant.Main.startAnt(Main.java:217)
at org.apache.tools.ant.launch.Launcher.run(Launcher.java:257)
at org.apache.tools.ant.launch.Launcher.main(Launcher.java:104)
Not sure what else needs to be added..
