Gradle JaCoCo - Inkompatible Version 1006

Ein Gradle Build + JaCoCo-Bericht.

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. Problem

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

$ gradle jacocoTestReport

Ausgabe

* 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

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

2. Lösung

Es sieht so aus, als ob das Gradle JaCoCo-Plugin nicht mit JaCoCo0.7.5kompatibel ist. Um dies zu beheben, stufen Sie JaCoCo auf Version0.7.4+herunter

build.gradle

    jacoco {
        toolVersion = "0.7.4+"
    }

Versuchen Sie bei einem ähnlichen Fehler "Inkompatible Version 100x", die JaCoCo-Version herunterzustufen oder zu aktualisieren.
