android - Android:build.gradle中的重复条目

Question

我试图用Android Studio运行我的Android应用程序，但显示以下消息时显示错误。

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.transform.api.TransformException: java.util.zip.ZipException: duplicate entry: com/mikepenz/iconics/core/BuildConfig.class

似乎有一个重复的库，所以这就是它停止运行的原因。但老实说，我不知道应该使用build.gradle文件修复哪个问题。所以我把build.gradle文件放在这里，有人请帮帮我。

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

//wrap with try and catch so the build is working even if the signing stuff is missing
try {
    apply from: '../../../signing.gradle'
} catch (ex) {
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.marshall.opensurvey"
        minSdkVersion 15
        targetSdkVersion 23

        applicationVariants.all { variant ->
            variant.outputs.each { output ->
                def file = output.outputFile
                def fileName = file.name.replace(".apk", "-v" + versionName + "-c" + versionCode + ".apk")
                output.outputFile = new File(file.parentFile, fileName)
            }
        }
    }
    buildTypes {
        debug {
            applicationIdSuffix ".debug"
            versionNameSuffix "-DEBUG"
            try {
                signingConfig signingConfigs.debug
            } catch (ex) {

Answer 1

您的依赖项存在冲突。
duplicate entry: com/mikepenz/iconics/core/BuildConfig.class
这意味着您的两个依赖项包含此类

// Android Iconics Library by Mike Penz
compile 'com.mikepenz:iconics-core:1.7.9@aar'
compile 'com.mikepenz:google-material-typeface:1.2.0.1@aar'

// AboutLibraries by Mike Penz
compile('com.mikepenz:aboutlibraries:5.2.5@aar') {
    transitive = true // <- Why?
}

我的猜测是不应该指定 transitive或 com.mikepenz库之一实际上包含其他库之一。例如，如果 iconics-core中包含 aboutlibraries，则应通过以下方式将其排除

compile('com.mikepenz:aboutlibraries:5.2.5@aar') {
    exclude module: 'com.mikepenz', name: 'iconics-core'
}

通过 dependencies运行gradle任务 gradle dependencies，可以轻松找到依赖关系问题。这显示了一个不错的库图表，该库依赖于其他库
