How to set jacoco coverage percentage to 60% at child's pom?

Question

Can some one tell me how to set Jacoco code coverage to a certain percentage in Child's POM. I have a parent dependency which is expecting 80% coverage. I need to limit that to 60% in my child project. I am setting 0.600 under child's pom properties. But this is not overriding the parent's coverage goal which is 80%. Any comments are appreciated..

<jacoco.percentage.instruction>0.600</jacoco.percentage.instruction>

you sure this is the jacoco plugin? the docs don't mention this property at all: https://www.eclemma.org/jacoco/trunk/doc/check-mojo.html - and the limit config looks quite different. or is this some own build property like here: https://automationrhapsody.com/automated-code-coverage-of-unit-tests-with-jacoco-and-maven/ ? you can always run your build with -X to see the plugin config or mvn help:effective-pom to figure out whats going on. worst case is add the complete plugin config into your pom — wemu, Jun 14 '19 at 23:34
config aftr mvn effective-pom ` default-check check INSTRUCTION 80.0% ` — Sunil, Jun 17 '19 at 18:37
well, I would think that config is in some parent pom somewhere. if it is using a property make sure its the correct one. — wemu, Jun 17 '19 at 18:55

The key is we cannot override just properties of Jacoco. I have copied the below parent's pom plug in to my project and I have updated the minimum covered ratio to 60% where it was 80% in parent's pom. This is working for me.
