安卓jacoco覆盖空与摇篮 [英] android jacoco coverage empty with gradle

问题描述

我试图让jacoco创造code覆盖率报告我的Andr​​oid测试项目。我有以下的build.gradle：

I'm trying to make jacoco create a code coverage report for my android test project. I have the following in build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'jacoco'
...
jacoco {
    toolVersion = "0.7.1.201405082137"
}
...
android {
    buildTypes {
        release {
        }
        debug {
            testCoverageEnabled true
        }
    }
}

当我运行gradlew -i createDebugCoverageReport，我得到一个覆盖报告，但它是空的。在摇篮执行结束如下：

when I run gradlew -i createDebugCoverageReport, I get a coverage report, but it's empty. the end of the gradle execution is as follows:

:androidTest:connectedAndroidTest (Thread[main,5,main]) completed. Took 2 mins 36.951 secs.
:androidTest:createDebugCoverageReport (Thread[main,5,main]) started.
:androidTest:createDebugCoverageReport
Executing task ':androidTest:createDebugCoverageReport' (up-to-date check took 0.006 secs) due to:
  Output file /home/akos/src/androidTest/build/outputs/reports/coverage/debug has changed.
  Output file /home/akos/src/androidTest/build/outputs/reports/coverage/debug/index.html has been removed.
  Output file /home/akos/src/androidTest/build/outputs/reports/coverage/debug/.resources/package.gif has been removed.
[ant:reportWithJacoco] Loading execution data file /home/akos/src/androidTest/build/outputs/code-coverage/connected/coverage.ec
[ant:reportWithJacoco] Writing bundle 'debug' with 3 classes
:androidTest:createDebugCoverageReport (Thread[main,5,main]) completed. Took 0.215 secs.

BUILD SUCCESSFUL

Total time: 4 mins 53.467 secs

而事实上，上述提及的coverage.ec文件是空的（0长度）

and indeed, the coverage.ec file referenced above is empty (of 0 length)

在目录中生成/中间体/覆盖，仪表类/，我似乎有仪表类文件

in the directory build/intermediates/coverage-instrumented-classes/ , I seem to have the instrumented class files

这是与摇篮2.1

我是什么做错了吗？

推荐答案

Jacoco应该是机器人关闭和jacoco插件声明里面是没有必要的：

Jacoco should be inside of the android closure and the jacoco plugin declaration is not necessary:

apply plugin: 'com.android.application'
...
android {
    buildTypes {
        release {
        }
        debug {
            testCoverageEnabled true
        }
    }
    jacoco {
        toolVersion = "0.7.1.201405082137"
    }
}
