Travis CI & CodeCov安卓

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。

.travis.yml：

after_success:
- bash <(curl -s https://codecov.io/bash)

build.gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        classpath 'com.dicedmelon.gradle:jacoco-android:0.1.1'
        // 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(应用程序)：

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

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    defaultConfig {
        applicationId "<ID>"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            testCoverageEnabled true
        }
    }
    testOptions {
        unitTests.returnDefaultValues = true
    }
    lintOptions {
        abortOnError false
    }
    productFlavors {
        free {}
        paid {}
    }


    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        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', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:support-v4:24.2.1'
    compile 'com.android.support:design:24.2.1'
    compile 'com.android.support:support-vector-drawable:24.2.1'
    testCompile 'junit:junit:4.12'
    compile files('libs/themoviedbapi-4.3.jar')
    compile files('libs/api-common-2.0.jar')
    compile files('libs/commons-codec-1.9.jar')
    compile files('libs/commons-lang3-3.4.jar')
    compile files('libs/httpcore-4.4.3.jar')
    compile files('libs/jackson-annotations-2.7.1.jar')
    compile files('libs/jackson-core-2.7.1.jar')
    compile files('libs/jackson-databind-2.7.1.jar')
    compile files('libs/slf4j-api-1.7.16.jar')
}

我们尝试运行的测试是一个仪表化测试。Travis日志上的输出如下所示：

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

此外，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Travis甚至没有通过它。

有没有人能帮我解决这个烂摊子？

Answer 1

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

HttpRequestBase#releaseConnection()方法是在4.2 version中明确添加的。

也许你有jar地狱。如果编译器没有编译错误，则可以在运行时加载类的另一个版本。真正的原因取决于您的构建工具。如果你使用的是maven/gradle，可能会有一些传递依赖。

所以实际上HttpRequestBase#releaseConnection()方法只是对AbstractExecutionAwareRequest#reset()代理调用。而AbstractExecutionAwareRequest#reset()只是取消方法的执行。也许这不是你所需要的。

执行和释放httpClient资源的正确方法是关闭httpResponse，这意味着您可以在httpClient的内部threadPool中释放线程。

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中，您将看到不再使用.releaseConnection() (它已被弃用)，而是关闭

对象以确保关闭连接。

尝试不同的httpclient或httpcore版本(来自here)：

看起来您有一个包含旧/新版本BasicHttpContext的jar文件。如果有直接冲突，你会收到一个ClassNotFoundException。ClassLoaders对于这类事情通常都是笨蛋。在这种情况下，类exists没有编译另一个库(我相信是httpclient调用上下文)所针对的方法。

对于23+接口，也可以在您的/app/build.gradle like this中添加the removed apache library

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

ApacheAndroid6.0版本删除了对

HTTP客户端的支持。如果您的应用程序正在使用此客户端，并且目标是Android2.3(API9级)或更高版本，请改用HttpURLConnection类。此API效率更高...

this article和this sample似乎对配置Android和Travis-ci的编解码器很有用：

生成检测测试代码覆盖率报告的

需要对构建脚本进行较小的更改。

android {
  buildTypes {
    debug {
      testCoverageEnabled true
    }
  }
}

为了避免通过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，我们需要配置报告输出：

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