jacoco lost some coverage

[felix1...@gmail.com]

JaCoCo version:0.7.8
Operating system:linux
Tool integration: Maven+jacoco agent

I use jacoco agent to dump exec file,then use maven-plugin generate report

@Override
public GetCTaskTreeTypeResponse getCTaskTreeType(GetCTaskTreeRequest request) throws Exception {
GetCTaskTreeTypeResponse responseType = new GetCTaskTreeTypeResponse();
ResponseStatusType responseStatusType = new ResponseStatusType();

try {
responseType = TaskBusiness.getCTaskTreeType(request);
responseStatusType.setAck(AckCodeType.Success);

In this class, TaskBusiness.getCTaskTreeType(request) is covered ,but TaskBusiness's coverage is 0%.

Hi,

on the top right corner of the HTML report there is a link "sessions".
On that page:

1) Is the your class TaskBusiness listed?
2) Does the TaskBusiness entry have a html link on the sessions page?

Also check your maven build output: Is there any message from the report
goal?

Cheers,

yes,on the session page,TaskBusiness is listed:
hotel.order.suppliertaskservice.business.TaskBusiness 24709a23be503103
but no html link on the TaskBusiness entry.

on maven output:
[WARNING] Execution data for class hotel/order/suppliertaskservice/business/Task
Business does not match.

i don't know how is this, how to fix this issue?

If class used at runtime during collection of his coverage into "jacoco.exec" is not the same as class used during generation of report from "jacoco.exec", then message  "Execution data for class ... does not match" is shown. Before fix, first required to understand what is a cause of this in your case, and this requires more details about your case, so please read http://www.jacoco.org/jacoco/trunk/doc/classids.html , in particular chapter "What can cause different class ids?"
