This fixes #9539.

The diff shows strange changes in build.gradle, which I cannot check on my mobile.

changes were jackson dependencies
I am getting failed test 'cannot generate preview' and no such element

I assume, you are executing CitaviXmlImporterFilesTest. What else do you execute?

@psyren99 Thank you for starting to look into that. While trying to understand your issue, I fixed some (other) code. These fixes were submitted separately at #11571

While working on your code, I came across https://stackoverflow.com/q/43574426/873282. Then I wondered, why the hell we want to introduce another dependency.

Then, I re-read the issue #9539. There was an issue at the discription. The gradle target to remove should be generateCitaviSource not generateEndnoteSource. I fixed that.

Thus, your PR should start with removing generateCitaviSource and the .xsd file. Then, you will see that your code does not compile at all.

I hadded coding hints to the issue desription #9539. Maybe, they help you to work on this.

Hint: More than half of the lines will be changed.
