Jenkins jacoco plugin fails to when running on slave machine:

The file does exist on the Jenkins master, so it yhas obviously been pulled back/copied:

ll /omi/jenkins/jenkins_home/jobs/PSD2-dev-jacoco/builds/23/jacoco/sources/uk/co/ybs/ecom/ooba/authentify/AuthentifyException.java

As a workaround I can prevent the pluging from finding any source files, by changing 

jacoco classPattern: 'builds/*/classes', execPattern: 'builds/jacoco//.exec', sourcePattern: 'yoa/*/java'

to 

jacoco classPattern: 'builds/*/classes', execPattern: 'builds/jacoco//*.exec', sourcePattern: ''

surprisingly adding 

, skipCopyOfSrcFiles: true

does not fix the issue. Note that jacoco is running on a slave machine.
