Question

我最近将我的Android Studio更新为3.1.0，我使用的是Gradle 4.4.0，自从我更新了IDE以来，我一直遇到Jacoco的问题。我遇到了运行时崩溃，如下所示：

以下是我的Gradle文件的样子：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
apply from: 'gradle/configurations.gradle'
apply from: 'gradle/gradleLintConfig.gradle'

buildscript {

    repositories {
        google()
        jcenter()
        mavenCentral()
        maven {

        }

        maven {
            url "https://maven.fabric.io/public"
        }
    }
    dependencies {
        // 3.0.1 (November 2017) - is a minor update to support Android Studio 3.0.1, and includes general bug fixes and performance improvements.
        classpath 'com.android.tools.build:gradle:3.1.0'
        classpath 'com.google.gms:google-services:3.2.0'

        //Here is Jacoco reference
        classpath 'org.jacoco:org.jacoco.core:0.8.0'

        // Nebula lint is used as a lint for our Gradle scripts. It helps identify if our
        // Gradle scripts have unused dependencies for example. Also, it checks for conformance
        // to Gradle standards.
        classpath 'com.netflix.nebula:gradle-lint-plugin:9.0.0'

        //Crashlytics - Crash reporting
        classpath 'io.fabric.tools:gradle:1.25.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
       }

    }

    tasks.withType(JavaCompile) {
        sourceCompatibility = "1.8"
        targetCompatibility = "1.8"
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这是app build.gradle文件：

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply from: "$project.rootDir/gradle/findbugs.gradle"
apply plugin: 'jacoco'

jacoco {
    toolVersion = '0.8.0'
}
...
 buildTypes {
        release {
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            minifyEnabled false
        }
        debug {
            versionNameSuffix="-debug"
            debuggable true
            /**
             *  Code below is commented out because it causes build issue
             *  when using newer version of gradle (3.1.0)
             */

            testCoverageEnabled true
            minifyEnabled false


            }
        }
    }
...
dependencies {
...

}

我不知道问题所在。我试图将.jar文件直接添加到项目中，结果相同。如果有人能提供帮助，我将永远感激不尽！

Answer 1

当从android studio / idea启动构建时，gradle 4.6和android plugin 3.1.0存在相同的问题。但是，当我使用gradle构建apk并将其与adb一起部署时，效果很好。

因此，看来该问题与IDE本身有关。它没有将正确的jacoco版本打包到apk。

编辑：我已禁用即时运行，现在可以正常运行了。

Answer 2

我不能说我的答案是确定的问题，因为我无法在app build.gradle中看到你的依赖项，但是使用这个最新版本的Gradle“compile”不再受支持。这可能是您的build.gradle或Jacoco的build.gradle的根本原因。

Jacoco与Gradle 3.1.0一起运行
