Hello Jenkins developers,
I’m currently developing a Jenkins plugin for deploying artifacts to a
proprietary software by Hewlett Packard Enterprise. Therefore, I’m using the
software’s Java API.
The initial configuration of the job and the post-build step are working
fine. The deployment works as well.
But when I open the job’s configuration again, I’m receiving an exception
once I click on apply or save. I’m receiving a NoClassDefFoundError for a
proprietary class of the API.
My question is: why is it even using the API on saving the configuration?
What exactly happens when I click save? I only use the API in my perform
method.
Here is the exception:
javax.servlet.ServletException: java.lang.NoClassDefFoundError:

I’m also seeing an error on the server-side of the software: 2016-08-17
13:23:41,456 ERROR [qtp1548928899-112733] (ApiServlet.java:126) - Denied
downloading of class com/hp/ucmdb/protocol/schema/Protocol.class
I really want to understand what happens when I click the save button? Why
is Jenkins trying to connect to the server and using the API?
Any help is highly appreciated. If you need further information, I’m happy
to provide them.
Thanks and best regards
Moritz
