Subject Re: ANT: Build Script Error: net/sf/antcontrib/antlib.xml. It could not be found
Date Wed, 12 Aug 2009 12:25:43 GMT

Hi,
Initially the error was follows:
***************E 1 ******
brgeda002:/u06/bacms/apps/DEVR1_5/logs>tail -100f
build_DevR1-5_20090811-145601.log
  [taskdef] Could not load definitions from resource
net/sf/antcontrib/antlib.xml. It could not be found.

init:
     [echo] initupdate Build Started at Tue Aug-11 14:56:9:532 EDT 2009 for
the Iteration: R1_5 !!!
[propertyfile] Updating property file: /u06/bacms/props/bldstats.properties

updateview:

BUILD FAILED
file:/u06/bacms/xml/clean_build.xml:164: Could not create task or type of
type: stopwatch.

Ant could not find the task or a class this task relies upon.

This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'stopwatch'.
   Fix: check your spelling.
- The task needs an external JAR file to execute
   and this is not found at the right place in the classpath.
   Fix: check the documentation for dependencies.
   Fix: declare the task.
- The task is an Ant optional task and optional.jar is absent
   Fix: look for optional.jar in ANT_HOME/lib, download if needed
- The task was not built into optional.jar as dependent
   libraries were not found at build time.
   Fix: look in the JAR to verify, then rebuild with the needed
   libraries, or download a release version from apache.org
- The build file was written for a later version of Ant
   Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
   and needs to be declared using <taskdef>.

Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath

Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.

Total time: 6 seconds

***************E 1 ******

The build script for the above mentioned error contained these lines:
********** Script 1 *******
<taskdef resource="net/sf/antcontrib/antlib.xml"/>

********** Script 1 *******
Also for the script 1, the classpath did not contain any references to ant
contrib jars.

Now the script has been modified to:
************ Script 2 *************
<taskdef resource="net/sf/antcontrib/antlib.xml">
        <classpath>
        <pathelement
location="/home/bacmsadm/apache-ant-1.7.1/lib/ant-contrib-1.0b3.jar" />
        </classpath>
        </taskdef>
************ Script 2 *************

This script results in the error that I have with "ignore" task def.
Further I have not changed the classpath.

Request, kindly help.
Thanks,
Regards,
Ravi V
