Unit tests using Spark do not run any more from IntelliJ IDEA

I had to re-import my SBT project into IDEA, cleaned it thoroughly (git clean -fdx) and even did an "Invalidate caches / restart". Now, all my unit tests using the Spark context fail with:

java.lang.SecurityException: class "javax.servlet.FilterRegistration"'s signer information does not match signer information of other classes in the same package

I already searched and dug around and found out that I have to exclude dependencies on javax.servlet on my dependencies on hadoop-common. I did this, but it did not help.

When running the tests from the console with sbt test, everything runs fine.

What can I additionally check?

EDIT: I even re-imported everything from scratch, including deletion of the .ivy2 folder, and it did not help.

I had to add the exclude for javax.servlet to ALL my Hadoop dependencies!
