"Failed to resolve :sdk-release: "哪个是 aar 文件

Question

我之前问过一个关于我的项目的问题，仍然需要帮助。

安卓工作室 3 分级同步问题

现在我有另一个我无法弄清楚的问题。 当我尝试构建我的项目时，出现此错误：

错误：无法解决： ：sdk 版本：

我的 sdk-release.aar 文件在 projectFolder>libs>aar 和 sdk-release 文件夹中

该错误是什么，我该如何解决？

我的build.gradle代码现在是这样的

buildscript {
    repositories {
        mavenCentral()
        mavenLocal()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
    }
}
repositories {
    mavenCentral()
    mavenLocal()
}
apply plugin: 'com.android.application'
android {
    compileSdkVersion 23
    buildToolsVersion '26.0.2'
    defaultConfig {
        applicationId 'com.kofax.sdk.samples.easysnap'
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName '1.0'
    }
    sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }
    buildTypes {
        release
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
    }
    lintOptions {
        abortOnError false
    }
}
configurations.all {
    resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
}
dependencies {
    def sdkRef
    project.getRootProject().allprojects.each { proj ->
        if (proj.name.toLowerCase().equals('sdk')) {
            sdkRef = proj;
            return true;
        }
    }
    if (sdkRef) {
        println "SDK present in project; using project reference as dependency"
        compile sdkRef
    } else {
        println "SDK is not present in project; dependency reference"
        repositories {
            flatDir { dirs 'libs' }
        }
        implementation (name: 'sdk-release', ext: 'aar')
    }
    compile fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:23.4.0'
}

Answer 1

更改代码：

implementation (name: 'sdk-release', ext: 'aar')
compile fileTree(dir: 'libs', include: ['*.jar'])

自

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation fileTree(dir: 'libs', include: ['*.aar'])

或

implementation fileTree(dir: 'libs', include: ['*.jar','*.aar'])
