Android 启用 jack 的 Studio 构建错误

Question

所以我最近将 Android Studio 默认值 JDK 更改为 Java 8，这样我就可以使用 Lambda 表达式了。我必须启用 Jack 才能让 gradle 构建，但现在当我尝试重建我的应用程序时，我收到大约 3 个不同的错误，这些错误似乎来自 Jack。我似乎找不到任何这些问题的根源，并希望继续使用 J8 进行构建。非常感谢任何对此的见解或帮助。以下是我在构建过程中遇到的错误：

1)

Error:Library reading phase: Type javax.inject.Named from file 'C:\Users\nicholas\AndroidStudioProjects\BaseIntegrations\app\build\intermediates\jill\debug\packaged\javax.inject-2.4.0-b10-e2682135301b663484690f1d3a4a523bcea2a732.jar' has already been imported from file 'C:\Users\nicholas\AndroidStudioProjects\BaseIntegrations\app\build\intermediates\jill\debug\packaged\javax.inject-1-4a242883e90a864db3b80da68e11a844f842d2df.jar', type 'javax.inject.Named' (see property 'jack.import.type.policy' for type collision policy)

这是应用级别build.gradle：

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.1"

    defaultConfig {
        applicationId "com.nicholas.baseintegrations"

        jackOptions {
            enabled true
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    useLibrary  'org.apache.http.legacy'

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.2.0'
    compile 'com.google.android.gms:play-services-gcm:9.4.0'
    compile project(path: ':backend', configuration: 'android-endpoints')
    compile "com.getbase:basecrm-java:1.4.3"
    compile 'com.android.support:recyclerview-v7:24.2.0'
    compile 'com.android.support:palette-v7:24.2.0'
    compile 'com.android.support:cardview-v7:24.2.0'

    compile group: 'org.glassfish.jersey.media', name: 'project', version: '2.23.2', ext: 'pom'
}

非常感谢所有帮助，因为我知道这是一个新事物，但似乎无法找到有关 Jack/J8 构建过程的问题。提前致谢。

Answer 1

我们正在调查此问题，我认为这是由于 Jack 和 javac 的 Android Gradle 插件的不同行为所致。作为解决方法，您可以在 jackOptions

中尝试此操作

additionalParameters = [ "jack.import.type.policy" : "keep-first" ]

但请注意，使用该选项，Jack 将保留它遇到的 class 的第一个定义。

Answer 2

我最终解决了这个构建问题。我的一个依赖项是添加第二个 javax.inject 库，它抛出这些构建错误，说 javax.inject jar 已经从前一个导入。

所以我有 javax.inject-1 和 javax.inject-2.4.0-b10。我最终从我的一个依赖项中排除了 javax.inject 模块，它解决了构建问题并且现在工作正常。

这是我的应用程序的依赖项部分 build.gradle：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile project(path: ':backend', configuration: 'android-endpoints')
    compile group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.21'
    compile (group: 'org.glassfish.jersey.media', name: 'project', version: '2.23.2', ext: 'pom')
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.google.android.gms:play-services-gcm:9.4.0'
    compile ('com.getbase:basecrm-java:1.4.3') {
        exclude (group: 'javax.inject', module: 'javax.inject')
    }
    compile 'com.android.support:recyclerview-v7:24.2.1'
    compile 'com.android.support:palette-v7:24.2.1'
    compile 'com.android.support:cardview-v7:24.2.1'
    compile 'com.android.support:design:24.2.1'
}

并且您可以在basecrm 依赖项中看到组排除。因此，如果其他人遇到此问题，请注意来自某些依赖项导入的重复外部库。

我遇到了同样的问题，然后我在这两个jar中找到了相同的包，但是它们不是同一个版本。所以修改为他们有相同的版本。
