I am using Jenkins in Windows, when I build the project I am getting the below error on Ant task pdepend.
pdepend:
[exec] Can't find the custom report class: --jdepend-chart=C:\Program Files\Jenkins\workspace\Tracking/build/pdepend/dependencies.svg
[exec] Result: 1
PMD is working fine without error and getting graph in Project Dashboard page.
This error means exactly what it says: the file could not be found at that location.
I would double check your configuration, as the following path from your error message seems wrong:
--jdepend-chart=C:\Program Files\Jenkins\workspace\Tracking/build/pdepend/dependencies.svg
Namely the backslashes becoming forward slashes halfway through the path name. With the limited information available, that appears to be your problem.
