Error Code creating JUnit Report

I wanna create a JUnit Test report with Apache Ant (I use the free version of Soap UI). The problem I have is when I enter the command in the cmd I get following error:

I tried to do file in the orderer where the reporst should be created but still get the same error.

Does anyone know how to fix that?
