The application runs using a self-packaged jacocoagent.jar. After subsequently using jacococli.jar to perform Pre-Instrumentation on a certain class， occurs NoClassDefFoundError or ClassNotFoundException for class org.jacoco.agent[...]Offline

I have packaged my own jacocoagent.jar. After packaging, the package name for the internal package is org.jacoco.agent.rt.internal instead of the official org.jacoco.agent.rt.internal_aeaf9ab.

I have a scenario where I use Arthas to perform retransform, so I used the official jacococli.jar for offline instrumentation. However, after instrumentation, the introduced package is org.jacoco.agent.rt.internal_aeaf9ab instead of org.jacoco.agent.rt.internal, which results in a NoClassDefFoundError or ClassNotFoundException for the class org.jacoco.agent[...]Offline.

I also checked the similar issue in the JaCoCo FAQ https://www.jacoco.org/jacoco/trunk/doc/faq.html, but it does not address my specific problem.

How can I handle this situation? How can I ensure that the fully qualified name of the Offline class introduced by offline instrumentation is org.jacoco.agent.rt.internal.Offline instead of org.jacoco.agent.rt.internal_aeaf9ab.Offline?

Hi,

there is a couple of reasons why we need to rename the runtime package, some are described here: https://www.jacoco.org/jacoco/trunk/doc/implementation.html

I see two options:

1) Use the JaCoCo build where the instrumentation and the runtime package use the same generated package name (which is derived from the Git commit id)

2) Also build your own jacococli.jar

Out of curiosity: Why do you need to build your own jacocoagent.jar in the first place?

Regards,

-marc
