Hi,
this happens if classes at runtime are different from the class files at
report generation time. There is a couple of reasons, why this could
happen. Please see our documentation at
http://eclemma.org/jacoco/trunk/doc/classids.html

What can cause different class ids?
Class ids are identical for the exact same class file only
(byte-by-byte). There is a couple of reasons why you might get different
class files. First compiling Java source files will result in different
class files if you use a different tool chain:
* Different compiler vendor (e.g. Eclipse vs. Oracle JDK)
* Different compiler versions
* Different compiler settings (e.g. debug vs. non-debug)
Also post-processing class files (obfuscation, AspectJ, etc.) will
typically change the class files. JaCoCo will work well if you simply
use the same class files for runtime as well as for analysis. So the
tool chain to create these class files does not matter.
Even if the class files on the file system are the same there is
possible that classes seen by the JaCoCo runtime agent are different
anyways. This typically happens when another Java agent is configured
/before/ the JaCoCo agent or special class loaders pre-process the class
files. Typical candidates are:
* Mocking frameworks
* Application servers
* Persistence frameworks

I was getting proper report over last month. And I recently havent
made any version updates/changes.
I see the following error during report generation and it gives only
partial coverage. The classes having these errors are skipped from the
coverage.
report-int:
[jacoco:report] Loading execution data file
/app/workspace/Functional_Code_Coverage/IRO/merges/jacoco-int-merged.exec
[jacoco:report] Writing bundle 'JaCoCo-INT' with 147 classes
[jacoco:report] Classes in bundle 'JaCoCo-INT' do no match with
execution data. For report generation the same class files must be
used as at runtime.
[jacoco:report] Execution data for class ******* does not match.
[jacoco:report] Execution data for class ****************** does not
match.
Does anyone have this issue earlier?
