Error Creating Report

[Stanley Chong]

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

Hi Stan,

are you using Ant? In this case please run your build with the Option -v to get more debug information and provide the output.

Also: What version of JaCoCo are you using?

I'm working with some guys that are off site for this.  They are using ant.  I believe that they ran it with the -v option.  I will ask them what version of JaCoCo that they are using when they get back from vacation on the 1st of May.  Sorry for the delay!

Hi,

Try running ant in debug mode, it could be due to duplicate classes with same package name.

ant -d report

Thanks,

Here's the info that I get from them.  

They are using Jacoco 0.7.6.  Their errors when they run with the -v option are:

…

Hi,

if you run Ant -v there should be a Java stack trace after the line with "Error while creating report".

Please provide this stack trace for further investigation.

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.

Thank you very much!  That worked!
