Hi,
the stack trace points out the problem:
"Class HelloWorld is already instrumented."
Report generation cannot work on instrumented classes. You need to
supply the original classes.

Hi,
We are trying to use JaCoCo on a Java program that is compiled to
machine code. We can get the jacoco.exec to be created, but when
we try to generate the report, we get the following error:
Buildfile: build.xml
Report:
[jacoco:report] Loading execution data file
/home/s_mrscha/bld24/jacoco.exec
BUILD FAILED
/home/s_mrscha/bld24/build.xml:23: Error while creating report
Total time: 6 seconds
And line 23 is just the first line of the ant <jacoco:report>
task… so that doesn’t seem to be useful.
Is there something else that would enable us to see a more
descriptive error so we can fix this problem?
Thanks,
Stan
