I have a maven project .I added the following to the pom.xml :
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.6.201602180812</version>
<executions>
<execution>
<id>jacoco-instrument</id>
<phase>test</phase>
<goals>
<goal>instrument</goal>
</goals>
</execution>
</executions>
</plugin>

when I do mvn clean install , I get

How to resolve ?

[Evgeny Mandrikov]

Quoting FAQ entry "Why do I get an error "ClassNotFoundException: org.jacoco.agent[...]Offline"?" at http://www.eclemma.org/jacoco/trunk/doc/faq.html :

If you use offline instrumentation the instrumented classes get a direct dependency on the JaCoCo runtime. Therefore jacocoagent.jar of the same JaCoCo version must be on the classpath and accessible from by the instrumented classes.

In other words - you probably forgot to add a dependency.

Also you can check our example of offline instrumentation - http://www.eclemma.org/jacoco/trunk/doc/examples/build/pom-offline.xml

Hi Evgeny,

Thanks for the quick response.

I am not running any tests yet. My main project and test code are in different places. I am trying to instrument the classes in main project by adding the jacoco plugin. When I do mvn install , I get the error.

I added the dependency

<dependency>
<groupId>org.jacoco</groupId>
<artifactId>org.jacoco.agent</artifactId>
<version>0.7.6.201602180812</version>
</dependency>
(version matches the plugin version)

Still getting the error

[Evgeny Mandrikov]

You are missing line "<classifier>runtime</classifier>" in specification of dependency.

Once again - please carefully study mentioned example. And documentation. Thank you for your understanding.

Hi,
Ran with and without classifier and scope . Facing the same issue.
Thanks for your response.

Sorry, but nothing to add to my previous messages. Unless if you'll make your project/example public, so that we can try it.
