Hi All,
I am currently facing the problem with loading findbug plugin on Hudson
2.2.1
The details of the environment are
OS - Windows 32 bit
Hudson - 2.2.1
Tomcat 6.0
Ant 1.8.1
maven 2
I am able to install Static Code Analysis and Findbug plugin. However after
installing when I restart Tomcat I get the following error. The reason it
quotes is that it is not able to initialize analysis-core. Can someone
provide some help on the issue.
Error Log
