"Error Processing Reports" error for a simple example project (that has worked in the past)

Support

Description

I teach an introductory Software Development Methods & Tools course. I have a trivial java project in a that I have also used in past semesters (simple java project w/ github, travis, and codecov). However, it is not working this semester and I have so far been unable to resolve it.

It looks as if everything runs fine and uploads in the build log.

However, then the error, “There was an error processing coverage reports” shows up.

Thanks in advance to any tips/guidance that anyone may have.

@sgeinitz, looking at the raw report uploaded to Codecov

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><!DOCTYPE report PUBLIC "-//JACOCO//DTD Report 1.1//EN" "report.dtd"><report name="ducksim"><sessioninfo id="travis-job-6a57798a-62fb-4254-8636-acf323733871-1385bae2" start="1616976403398" dump="1616976405070"/></report><<<<<< EOF

is the entire file. We see this as an empty file, as there is no information to parse here. I would guess there is an issue with the way those tools are pulling coverage.

Thank you for the quick reply. It seems that jacoco was creating html reports but not the necessary xml reports. This seems to be a somewhat common problem with jacoco.

I was able to resolve it by modifying the build configuration file slightly.
