Jacoco and Unit Tests Code Coverage with android-gradle-plugin >= 1.1

After the hassle, I decided to create an open source Gradle plugin for that.

Root build.gradle

buildscript {
    repositories {
        mavenCentral() // optional if you have this one already
    }
    dependencies {
        classpath 'com.vanniktech:gradle-android-junit-jacoco-plugin:0.16.0'
    }
}

apply plugin: 'com.vanniktech.android.junit.jacoco'

Then simply execute

./gradlew jacocoTestReportDebug

It’ll run the JUnit tests in Debug Mode and then give you the Jacoco output in XML and HTML form in the corresponding build directory.

It also supports flavors. Having 2 flavors red and blue those tasks would be created

• jacocoTestReportRedDebug
• jacocoTestReportBlueDebug
• jacocoTestReportRedRelease
• jacocoTestReportBlueRelease
