ERROR in jacoco check - The parameters 'rules' are missing or invalid

Question

This is the error I get when running mvn jacoco:check for a maven application. Due to that, the report is not generated.

 [ERROR] Failed to execute goal org.jacoco:jacoco-maven-plugin:0.8.3:check (default-cli) on project 

    Netflix: The parameters 'rules' for goal org.jacoco:jacoco-maven-plugin:0.8.3:check are missing or invalid -> [Help 1]
    org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.jacoco:jacoco-maven-plugin:0.8.3:check (default-cli) on project Netflix: The parameters 'rules' for goal org.jacoco:jacoco-maven-plugin:0.8.3:check are missing or invalid

This is my jacoco plugin in pom.xml. I think the rules are all okay. I'd like to know what's missing...

Does this answer your question? Running jacoco check goal with maven 3.5 – Brigade

Would be useful if jacoco/maven provided details rather than just "There was an error". – Justino

Answer 1

The jacoco:check goal is attached to Maven verify phase. You can check the same in jacoco:check

You need to run it using maven verify phase

mvn clean verify

Is there an explanation to why this will succeed but running mvn jacoco:check specifically fails? I'm new to and trying to understand how maven works. – Hydrochloride

@KwesiSmart probably this answer helps to understand. I'm also new, didn't understand much but there's some level of explanation at least https://mcmap.net/q/1161971/-running-jacoco-check-goal-with-maven-3-5 – Universalism
