问题

在androidTest目录下的一个文件中，我有这样一行代码，并得到了ClassNotFoundException。

Class<?> emmaRTClass = Class.forName("com.vladium.emma.rt.RT");

项目结构

build.gradle

./build.gradle

buildscript {
    ext.jacocoVersion="0.8.2"
    ...
    dependencies {
         ...
         classpath "org.jacoco:org.jacoco.core:$jacocoVersion"
    }
}

subproject.main/build.gradle

...
dependencies {
     ...
     jacocoAnt 'org.jacoco:org.jacoco.ant:0.8.1:nodeps'
}

apply plugin: 'jacoco'
...

据这称，

\x{e76f}\x{e76f}( org.jacoco )\x{e76f}\x{e76f}所有依赖项(包括所有依赖项)

等级依赖性：

查看subproject.main的依赖项

 $ ./gradlew app:dependencies | grep jacoco

输出是

Answer 1

终于我拿到了！这是因为testCoverageEnabled的默认值是false，如下面的配置所示。刚刚设置了

buildTypes {
    debug {
       ...
       if (isFromServer()) {
           testCoverageEnabled true
       }
    }
}
