Error occurs in jenkins build of unity
The output shows you the problem: you have script errors. Until you fix your script errors, you won't be able to build.
You haven't included the script errors, so no-one can give you any more info. When you fix them, you'll probably find that it's nothing to do with Jenkins, and the question title is unrelated.
Usual causes of this:
- You have some editor scripts in you project
- You forgot to put #if guards around editor scripts and/or external scripts
- You forgot to copy/paste one of your 3rd party libraries or plugins onto the machine where you're doign the build - and it's not in source control already (where it should be).
