JaCoCo not generating jacoco.exec until after skipping JaCoCo execution

Question

I\'m having trouble generating AHP reports via JaCoCo in one of my modules. When the build starts, I see JaCoCo correctly setting argLine with:

[INFO] jacoco.age         


        

Answer 1

for me one of the reason for exec file not getting generated is when i placed the prepare-agent , prepare-package goals inside plugin section of pluginManagement

when i tried the same outside pluginManagement , i was sucessfully able to run the same and jacoco-exec file was generated using mvn clean install command

my pomfile is as below :

  4.0.0
