Gradle JaCoCo - Version incompatible 1006

Un rapport de couverture Gradle build + JaCoCo.

build.gradle

    apply plugin: 'java'
    apply plugin: 'eclipse-wtp'
    apply plugin: 'jacoco' //code coverage

    repositories {
        mavenLocal()
        mavenCentral()
    }

    jacoco {
        toolVersion = "0.7.5+"
    }

    jacocoTestReport {
        reports {
          html.enabled = true
          xml.enabled = true
          csv.enabled = false
        }
    }

P.S Tested with Gradle 2.10

1. Problème

1.1 Run the jacocoTestReport task and hits the following error message :

$ gradle jacocoTestReport

Sortie

* What went wrong:
Execution failed for task ':jacocoTestReport'.
> Unable to read execution data file /home/example/workspace/hc/analyzer/build/jacoco/test.exec

1.2 Get more info with --stacktrace option.

$ gradle jacocoTestReport --stacktrace

Sortie -java.io.IOException: Incompatible version 1006.

2. Solution

On dirait que le plugin Gradle JaCoCo n'est pas compatible avec JaCoCo0.7.5, pour le réparer, rétrograder JaCoCo à la version0.7.4+

build.gradle

    jacoco {
        toolVersion = "0.7.4+"
    }

Pour une erreur similaire «Version 100x incompatible», essayez de rétrograder ou de mettre à niveau la version JaCoCo.
