Hi Marc,
Many thanks for the reply. I added the jacoco elements to a working
build.xml (pasted below). Now I am getting an error when the jacoco:report
element tries to read the jacoco.exec. When the jacoco:coverage element
runs there are no exceptions thrown, but the file is not getting generated.
BUILD FAILED
