Hi,
This has become a very big issue for me.
On a newly created build server, I am facing the error, that is given below.
Please help me...........
Any help and instructions and guidance will be greatly appreciated....

The build server has been created on Sun Solaris ....
ANT 1.7.1 has been installed...

Thank you very much...

[taskdef] Could not load definitions from resource net/sf/antcontrib/antlib.xml. It could not be found.

BUILD FAILED
file:/u06/bacms/xml/clean_build.xml:160: 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.

Welcome to JavaRanch!

Is antcontrib in your classpath?

Hi Jeanne,
Thank you very much for the reply.

Kindly advise.
I greatly appreciate your reply.

Hi Jeanne,

Here is the CLASSPATH

brgeda002:/u06/bacms/scripts>echo $CLASSPATH
/home/bacmsadm/apache-ant-1.7.1/lib/ant-contrib-1.0b3.jar:/home/bacmsadm/Partha/wmbideploy_01/ant.jar:/home/bacmsadm/Partha/wmbideploy_01/com.ibm.mq.jar:/home/bacmsadm/Partha/wmbideploy_01/ConfigManagerProxy.jar:
brgeda002:/u06/bacms/scripts>


Kinddly advise.
Thanks a lot,
Regards,

Hi Jeanne,
Here is the update.........

I removed any references from the CLASSPATH to ant-contrib jar, and modified the build script to add following lines:

<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>

The new error is as follows:

brgeda002:/u06/bacms/apps/DEVR1_5/logs>tail -100f build_DevR1-5_20090811-150220.log

BUILD FAILED
file:/u06/bacms/xml/clean_build.xml:72: taskdef class "ignore"/> cannot be found

Total time: 4 seconds
^C
brgeda002:/u06/bacms/apps/DEVR1_5/logs>


Please advise, how can I resolve this error.

Thanks,
Greatly appreciate your reply,

Regards,
Ravi V
