android - 无法读取映射文件，Gradle任务执行异常[Android]

标签 android gradle android-gradle-plugin

在构建发布版本时，我从 Gradle 收到了这个奇怪的错误。我在我的项目中设置了不同的风格，即 QC、Staging、Live。在 QC 和 Live flavor 上构建发布版本工作得很好，但每当我尝试通过 Staging Flavor 创建发布版本时，它都会抛出这个 gradle 异常。

我在我的 Android 项目上启用了 Multidex 和 proguard。自从我将编译和构建 SDK 升级到 Android M 后，就会抛出此错误。我已按照 Google Docs 中有关升级项目的所有说明进行操作。这是 build.gradle 文件的 fragment 。

android {
    compileSdkVersion 23
    buildToolsVersion "22.0.1"
    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "com.example"
        minSdkVersion 10
        targetSdkVersion 23
        versionCode 15091000
        versionName "5.0.2"
        multiDexEnabled true
    }

    dexOptions {
        incremental true
        preDexLibraries = false
        jumboMode = true
        javaMaxHeapSize "4G"

    }

    productFlavors {
        qc {
            applicationId = "com.example.qc"
            versionName "5.0.2.8"
            buildConfigField  "int", "appMode", "1"
        }
        dev {
            applicationId = "com.example.dev"
            versionName "5.0.2.8"
            buildConfigField  "int", "appMode", "2"
        }
        staging {
            applicationId = "com.example.staging"
            versionName "5.0.2.8"
            buildConfigField  "int", "appMode", "4"
        }
        prod {
            applicationId = "com.example"
            versionName "5.0.2.8"
            buildConfigField  "int", "appMode", "5"
        }
    }
    buildTypes {
        debug {
//            applicationIdSuffix ".debug"
            minifyEnabled false
            shrinkResources false
            debuggable true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        release {
            minifyEnabled true
            shrinkResources true
            zipAlignEnabled true
            debuggable false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LGPL2.1'
    }
}

我在 Stackoverflow 和 Google 论坛上对这个问题进行了很多研究。他们说，这可能是由于达到了 64k 的方法限制，为此，我现在正在使用 MultiDex 支持，为方法数大于 64k 的项目构建多个 dex 文件。但我想，它与抛出此错误的暂存构建没有任何关系，而其他风格正在生成发布构建而没有任何错误。

我没有看到产品口味的 build.gradle 文件有任何差异。有人碰巧遇到过这种问题吗？请帮忙!

最佳答案

我在使用 ProGuard 和 MultiDex 时遇到了同样的问题。我发现 NewRelic 插件 (v1.3.+) 向 mapping.txt 添加了一行，例如“# NR_BUILD_ID: XXXXX-XXXXXX-XXXXXXX-XXXXXXXX”，我认为这就是问题所在。

在Android gradle googlesource, groovy 文件中可以看到RetraceMainDexList (第 105 行)，如果在 mapping.txt 中找到以无空格开头且不包含“->”字符串的行，它将引发 RuntimeException("unable to read mapping file.")。因此，NR 附加到 ma​​pping.txt 的行引发此异常并导致:retraceMainDexClassList 任务崩溃。

如果删除#NR_BUILD_ID 行，应用程序运行正常。

我已将此问题发送给 NewRelic 支持，他们证实了我的发现。他们告诉我这个问题已发送给开发人员以处理此问题。

希望对您有所帮助。
