Offline instrumentation

[sharm...@gmail.com]

I am trying to estimate code coverage for system test. I did mvn clean test and got the classes instrumented . when I run tests ,I am not able to see the jacoco reports anywhere . What is the issue ?
attached the jacoco plugin spec in pom.xml

<plugin>
<groupId>org.jacoco</groupId>

1. Why not provide build log? Maybe it contains some error messages?
   
2. Do not mix on-the-fly instrumentation "prepare-agent" with pre-instrumentation (offline) "instrument".
3. If you are on Linux, then "/jacoco-ut" most likely refers to non-writable location.
4. Did you tried to study example that we provide in documentation - http://www.eclemma.org/jacoco/trunk/doc/examples/build/pom.xml ? You'll find it fully in attachment - unpack, run "mvn package", study together with documentation, apply learned materials on your project.
