Maven error message - Spring Boot

Hello you,

We are soon to be the proud users of our own Camunda server, but are having a few problems along the way.
Maybe you can help me?
We use Spring Boot and when we start Maven we get this error message:

com.example.workflow.util.WorkflowTest.txt (33.0 KB) TEST-com.example.workflow.util.WorkflowTest.xml (86.9 KB)

Have a great day and thanks for your help,

Sebastian
