我正在尝试从架构组件中使用 WorkManager。我已将 compileSdkVersion 和 targetSdkVersion 从 27 升级到 28。gradle 同步已成功完成。但是构建时错误不断弹出。由于“android.support:design”，android.support 库正在使用版本 28.0.0-rc02。

我尝试添加 PackagingOptions 以排除“proguard/androidx-annotations.pro”。但这没有帮助。但是这次我收到了不同的错误信息:

Program type already present: com.google.common.util.concurrent.ListenableFuture

我不知道出了什么问题。

build.gradle:

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

apply plugin: 'io.fabric'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.apps.test"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 5
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }

    signingConfigs {
        release
    }

    buildTypes {
        release {

        }
        debug {

            resValue "bool", "enableFirebase", "false"

        }
    }
}

编辑: 我已经在 gradle like in here 中实现了 PackagingOptions

packagingOptions {
    exclude 'META-INF/proguard/androidx-annotations.pro'
}

但这次我又遇到了 5 个错误:

1:

Program type already present: com.google.common.util.concurrent.ListenableFuture
Message{kind=ERROR, text=Program type already present: com.google.common.util.concurrent.ListenableFuture, sources=[Unknown source file], tool name=Optional.of(D8)}

2:

Caused by: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: ...

3:

Caused by: com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: ...

4:

Caused by: com.android.tools.r8.CompilationFailedException: Compilation failed to complete

5:

Caused by: com.android.tools.r8.utils.AbortException

最佳答案

根据 WorkManager 1.0.0-alpha09 release notes :

Known Issue

If you run into the following issue: "More than one file was found with OS independent path 'META-INF/proguard/androidx-annotations.pro'", please put the following in your gradle file as a temporary workaround while we fix the issue in alpha10:

android {
    packagingOptions {
        exclude 'META-INF/proguard/androidx-annotations.pro'
    }
}

编辑:您的其他错误是由 this issue 引起的:

It is done on purpose: https://groups.google.com/forum/#!topic/guava-announce/Km82fZG68Sw

New release of guava will be ready soon, that will resolve that issue automatically.

For now you can exclude "com.google.guava:listenablefuture" in your gradle file:

implementation("android.arch.work:work-runtime:1.0.0-alpha09") {
    exclude group: 'com.google.guava', module: 'listenablefuture' 
}
