OpenClover Check Goal calculates different coverage into Maven multi-module project than Log Edited

Hi all!


I'm facing some issues about how to check the coverage threshold with openclover maven plugin with a multi-module Maven Project.

I execute the tests with:

mvn clover:setup test clover:aggregate clover:clover


Then, i execute the Log goal with

mvn clover:log


After that, i'm trying to check the coverage with:

mvn clover:check -Dmaven.clover.targetPercentage=XX%


The build fails because clover calculates a different value, from parent project, compared to the HTML Report or Log goal


Here is the output:

INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.openclover:clover-maven-plugin:4.3.1:check (default-cli) on project example-parent: Build failed to meet Clover coverage targets: The following coverage targets for null were not met:
[ERROR] Total coverage of 53.5% did not meet target of 100%
[ERROR] -> [Help 1]


What am I doing wrong? 

Does Clover check goal require additional steps to work?

As you use 'clover:aggregate' it suggests that you have multiple modules in your project, am I correct? Maybe what happens is that clover:check is ran on a different clover.db file.

I suggest the following:

  • find all clover.db files generated in your project, including cloverMerge.db
  • run clover:check on all of them (passing cloverMergeDatabase or cloverDatabase options) 
  • check if any of these produce valid results

Note that clover:check searches for both cloverDatabase and cloverMergeDatabase

Note that clover:aggregate runs in the last Maven module being built and writes cloverMerge.db to that location. Which means that probably you may want to add cloverMergeDatabase parameter in your root pom to specify the location.
