recently I'm learning jacocoagent, I used the following command to start my project,
```nohup java -javaagent:/root/qa_charlyne/jacocoagent.jar=includes=*,output=file,destfile=/root/qa_charlyne/jacoco.exec -jar diff-code-coverage.jar > difflog.txt 2>&1```
but i failed to start up jacocoagent.jar: Failed to find Premain-Class manifest attribute in /root/qa_charlyne/org.jacoco.agent-0.8.5.jar Error occurred during initialization of VM agent library failed to init: instrument
i don't know why ,i need help
