Travis CI & CodeCov Android

Question

我正在尝试使用 Travis CI 并让它通过测试来查看 codecov 上的结果。

build.gradle：

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle(app):

apply plugin: 'com.android.application'
apply plugin: 'jacoco-android'

        }
        debug {
            testCoverageEnabled true
        }
    }
    testOptions {
        unitTests.returnDefaultValues = true
    }
    lintOptions {

    }
    productFlavors {

        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
}

dependencies {
    compile files('libs/httpclient-4.5.1.jar')
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

    })

    compile files('libs/jackson-databind-2.7.1.jar')
    compile files('libs/slf4j-api-1.7.16.jar')
}

我们正在尝试运行的测试是仪器化测试。 Travis 日志的输出如下所示：

com.example.fabian.tinf15b4_lsmf.SeeMovieDetailsTest > seeMovieDetails[test(AVD) - 5.0.2] [31mFAILED [0m
    java.lang.NoSuchMethodError: No virtual method releaseConnection()V in class Lorg/apache/http/client/methods/HttpRequestBase; or its super classes (declaration of 'org.apache.http.client.methods.HttpRequestBase' appears in /system/framework/ext.jar)

    at org.yamj.api.common.http.DigestedResponseReader.processRequest(DigestedResponseReader.java:119)

Tests on test(AVD) - 5.0.2 failed: Instrumentation run failed due to 'java.lang.NoSuchMethodError'
:app:connectedFreeDebugAndroidTest FAILED

还有自动生成的测试，它只是简单地将两个数字相加并检查结果，但特拉维斯甚至没有通过它。

谁能帮忙解决这个烂摊子？

Answer 1

阅读this related question 关于HTTPClient - NoSuchMethodError for .releaseConnection。

HttpRequestBase#releaseConnection() 方法定义添加在 4.2 version.

可能你有罐子地狱。如果编译器没有编译错误 可以在运行时加载该类的另一个版本。真正的原因 取决于您的构建工具。如果您使用的是 maven/gradle，则可以 是一些传递依赖。

所以实际上HttpRequestBase#releaseConnection() 方法只是代理 调用AbstractExecutionAwareRequest#reset()。和 AbstractExecutionAwareRequest#reset() 只是取消方法执行。 可能不是你需要的。

执行和释放httpClient资源的正确方法是 关闭httpResponse，表示可以在httpClient的释放Thread 内部线程池。

private static String makeRequest(HttpUriRequest httpRequest) throws IOException {
        CloseableHttpResponse httpResponse = httpClient.execute(httpRequest);
        try {
            HttpEntity httpEntity = httpResponse.getEntity();
            StringWriter writer = new StringWriter();
            IOUtils.copy(httpEntity.getContent(), writer, "UTF-8");
            return writer.toString();
        } finally {
            httpResponse.close();
        }
    }

在quickstart 你会看到 .releaseConnection() 不再使用（已弃用）， 而是关闭响应对象以确保连接 关闭。

尝试不同的httpclient或httpcore版本（来自here）：

您的 jar 文件似乎包含旧/新版本 基本的HttpContext。如果存在直接冲突，您将收到 类NotFoundException。类加载器通常是关于这个的混蛋 之类的事情。在这种情况下，类存在，但是，没有 另一个库的方法（我相信它是 httpclient 调用上下文）是针对编译的。

对于 API 23+，您还可以在 /app/build.gradle 中添加 the removed apache library like this：

android {
compileSdkVersion 24
buildToolsVersion "24.0.3"
    useLibrary 'org.apache.http.legacy'
    ...
}

Android 6.0 版本删除了对 Apache HTTP 客户端的支持。如果 您的应用正在使用此客户端并针对 Android 2.3（API 级别 9）或 更高，请改用 HttpURLConnection 类。这个API更多 高效...

this article 和 this sample 似乎有助于为 Android 和 Travis-ci 配置 Codecov：

生成仪器测试代码覆盖率报告需要 对构建脚本的微小改动。

android {
  buildTypes {
    debug {
      testCoverageEnabled true
    }
  }
}

为避免覆盖率报告忽略我们的测试，我们需要 配置以下设置：

android {
  testOptions {
    unitTests.all {
      jacoco {
        includeNoLocationClasses = true
      }
    }
  }
}

接下来，我们需要配置报表输出：

 jacocoAndroidUnitTestReport {
  csv.enabled false
  html.enabled true
  xml.enabled true
}
