android gradle 使用 jacoco，获取 "Error during Sync: Remote object doesn' t 存在!”

Question

在我的testdemo中，我使用了jacoco并且覆盖成功。

演示 build.gradle

android {
    jacoco {
        toolVersion "0.7.1.201405082137"
}
    buildTypes {
        debug {
            testCoverageEnabled true
        }
    }
}

但是在我的其他项目中，我得到了错误:

在我的例子中，这是通过使用尚未 root 的设备生成的。您是否尝试过在模拟器上运行测试？
