I am using Apache ANT 1.7 for building my projects.

I need logging during build using ant script (logging information like, build started, target started, target ended,build stopped).

Thanks

You could make it simple and use

<echo message="Build started" />

For very verbose output you can do

ant -d

See http://ant.apache.org/manual/index.html for the log4j config!

I've never run Ant with log4j logging, but i'd guess that would be even more verbose than the debug option - probably overkill

try this,
log4j.appender.stdout.layout.ConversionPattern=[%t] - %m%n

>>I've never run Ant with log4j logging

Actually, Ant uses log4j for printing messages even in console!

Thanks for your efforts
I used log4j and got this output in build.log file

I am running ant as
ant -listener org.apache.tools.ant.listener.Log4jListener -lib .

My pog4j.properties configuration code snippet and the output file is here

How can I specify the time.

log4j.rootLogger=ERROR, LogFile
log4j.logger.org.apache.tools.ant.Project=INFO
log4j.logger.org.apache.tools.ant.Target=INFO
log4j.logger.org.apache.tools.ant.taskdefs=INFO
log4j.logger.org.apache.tools.ant.taskdefs.Echo=WARN
 
log4j.appender.LogFile=org.apache.log4j.FileAppender
log4j.appender.LogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.LogFile.layout.ConversionPattern=[%6r] %8c{1} : %m%n
log4j.appender.LogFile.file=build.log
 
 
Output
