I use prqa plugin to do analysis on a windows agent. 

Previously it works well for all jobs, but recently we met a problem.

When use the plguin to do qac analyze, it will prompt an error like below:

and there is another weired thing, we still have a jenkins job that can do qac analyze and upload, except that job, other jobs using the plugin can't do qac analyze and will have the error. 

I don't know what's going on ?

I have tried below, but none worked

1. reinstall the plugins
2. upgrade to 3.3.5

any suggestions?
