Looks like for whatever reason the JaCoCo runtime is not on the
classpath or cannot be loaded in your testsetup.
You might check with the -X Maven option how the command line for your
test runtime looks like.
Also here you can find a working example:

Thanks @marc for your information. I'm trying to use the jacoco
offline instrumentation with the following configuration:
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.5.201505241946</version>
<executions>

<execution>
<id>default-report</id>
<phase>prepare-package</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.12.2</version>
<configuration>
<systemPropertyVariables>
<jacoco-agent.destfile>target/jacoco.exec</jacoco-agent.destfile>
</systemPropertyVariables>
</configuration>
</plugin>
and also with dependency:
<dependency>
<groupId>org.jacoco</groupId>
<artifactId>org.jacoco.agent</artifactId>
<classifier>runtime</classifier>
<version>0.7.5.201505241946</version>
</dependency>
but all tests failed due
to org/jacoco/agent/rt/internal_b0d6a23/Offline can not be found. Is
there anything wrong with my configration?

Hi,
JaCoCo works on class files only. It reports whatever it sees in the
class files which get instrumented and analyzed. Future versions
might
come with the option to filter certain constructs, but for AspectJ
this
will probably not work as you can inject any code.
To solve this you have to make sure that the class files get
instrumeted
by JaCoCo *before* AspectJ kicks in. If you use the AspectJ agent
it has
to be configured after the JaCoCo agent. If you want to
pre-compile your
classes you can use JaCoCo offline instrumentation first:
