The issue resolved after making the pluginFirstClassLoader config set to False in the maven-hpi-plugin.

The issue was the hibernate dom4j jar was loading before the jenkins core saxparser class which was causing the problem

Thanks to Jenkins-Ci wiki which explained a bit about this setting .. this setting is dangerous and might not behave like this in all scenarios ..

It's not resolving even after I made the settings as false in the pom. Any other way to solve the issue.

Hello mrandhikpurwala

Sorry for slow followup  - was busy with other tasks.  Can you provide with sample config.xml of the bombing project and other inputs  needed to reproduce
Thanks,
Serguei Kouzmine
