android gradle使用Jacoco，获取“同步时出错：远程对象不存在！”

Question

在我的测试演示中，我使用了jacoco并成功地获得了覆盖率

演示构建。格拉德尔

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

但在我的另一个项目中，我遇到了错误：

在我的例子中，这是使用一个没有根的设备生成的。您是否尝试在模拟器上运行测试？
