Resolve jacoco maven plugin - class already instrumented exception when building the project about carbon-secvault

[vermastuti]

As per my insight into this research: It is possible to also use offline-instrumented classes with the JaCoCo Java agent. In this case, the configuration is taken from the agent options. The agent must be configured in a way that pre-instrumented classes are excluded, e.g. with " excludes=* ". Otherwise it will result in error messages on the console if the agent instruments such classes again likewise in your case.
Jacoco plugin entry:-

<configuration> 
     <excludes> 
          <exclude>*</exclude> 
     </excludes> 
</configuration>

The agent jacocoagent.jar is part of the JaCoCo distribution and includes all required dependencies. A Java agent can be activated with the following JVM option(in command line):

-javaagent:[yourpath/]jacocoagent.jar=[option1]=[value1],[option2]=[value2]

As the agent jacocoagent.jar is part of the JaCoCo distribution, it gets automatically included in argLine parameter and need not be set explicitly, but we should to verify if jacocoagent.jar is shown as set in argLine while doing mvn clean install command.

For JaCoCo agent options, consider the following link: http://www.jacoco.org/jacoco/trunk/doc/agent.html

Hi Stuti,
I have been getting similar issues. So I tried the entry as suggested above. Now I am getting following error:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

Do you have any clue why this could be happening?

Thanks,
Smita
