Hi
I am completely new to grade/buildship, but want give it a try. I followed the tutorial https://guides.gradle.org/building-java-applications/

When I build the (admittedly) simple project I get an exception at the test phase, saying (see below). I first thought it could be a problem with the file permissions (the build directory had only .w.r..r..r and I changed to the full rights
thought I know, gradle has written the compiled classes in a subfolder). Any help is appreciated!:
