Real time ant build analyzer

问题

Is there any Ant tool to Analyze Ant build activities during run time? Due to lack of time i don;t want to go through each line of code in the ant script to understand what it is doing. It would be great if i can get any suggestions for anysuch tools.

Check out the ANT documentation on ANT loggers and listeners.

To print everything that ANT is doing I'd suggest using the very powerful log4j listener.

Example

The log4j listener needs some setup. Example can be run as follows:

ant bootstrap
ant -listener org.apache.tools.ant.listener.Log4jListener -lib .

It generates a log file with detailing each step within the build:

[     0]  Project : Build started.
[    94]   Target : Target "run1" started.
[   319]     Echo : Run1: Hello world
[   320]   Target : Target "run1" finished.
[   320]   Target : Target "run2" started.
[   321]     Echo : Run2: Hello world
[   321]   Target : Target "run2" finished.
[   321]   Target : Target "run" started.
[   321]   Target : Target "run" finished.
[   328]  Project : Build finished.

build.xml

<project name="ANT listener" default="run">

  <target name="bootstrap">
    <get src="http://search.maven.org/remotecontent?filepath=log4j/log4j/1.2.17/log4j-1.2.17.jar" dest="log4j.jar"/>

    <echo file="log4j.properties">

    </echo>
  </target>

  <target name="run" depends="run1,run2">
  </target>

  <target name="run1">
    <echo message="Run1: Hello world"/>

</project>
