I am trying to add an aggregated coverage report for the unit tests for a multi-module project. The coverage report is generated as expected for individual modules. But the aggregated report generated in the report module target is showing coverage as 0%
The structure of the modules as follows :
Root
|
|
- - - Components module
|
|
- - - - - - - - - Sub module A
|
|
- - - - - - - - - Sub module B
|
|
- - - - - - - - - Aggregate report module
I followed this sample project: https://github.com/jacoco/jacoco/blob/master/jacoco-maven-plugin.test/it/it-report-aggregate/pom.xml
The existing root pom contains plugin config as follows, I didn't change anything there :
