我有Android Studio Beta版。我创建了一个新项目,编译我的旧模块,但当我尝试启动应用程序时,它没有启动消息:

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

dexarchiivemergenerexception:无法合并dex

但是我不知道如何解决这个错误。我在谷歌上搜索了几个小时,但没有成功。

我的项目gradle:

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta6'
        classpath "io.realm:realm-gradle-plugin:3.7.1"
        classpath 'com.google.gms:google-services:3.1.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的应用程序gradle:

    apply plugin: 'com.android.application'

    compile project(path: ':loginregisterview')


}

我的模块gradle:

    apply plugin: 'com.android.library'
apply plugin: 'realm-android'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"

    defaultConfig {

    compile project(path: ':parser')

}

我的第二个模块:

     apply plugin: 'com.android.library'
apply plugin: 'realm-android'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {

        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    realm {
        syncEnabled = true
    }
    useLibrary 'org.apache.http.legacy'

    buildTypes {

当我没有导入第二个模块(解析器)时,应用程序没有在dex上崩溃,但当模块没有导入时,应用程序无法工作。: D: D


当前回答

对于我们的项目,我们不小心用不同的名字添加了同一个罐子两次。去掉其中一个就解决了问题。

其他回答

嗨,我也有同样的问题,几乎什么都试过了。所以,经过6个小时的挣扎,我终于解决了问题。

classpath 'com.google.gms:google-services:3.0.0'

Google-services 3.0在playServiceVersion: 11.6.0或更低版本的Studio 3.0不支持firebase。

implementation "com.google.firebase:firebase-messaging:$rootProject.ext.playServiceVersion"
implementation "com.google.firebase:firebase-core:$rootProject.ext.playServiceVersion"
implementation "com.firebase:firebase-jobdispatcher-with-gcm-dep:$rootProject.ext.jobdispatcherVersion"

解决方案:

我已将谷歌服务更改为

classpath 'com.google.gms:google-services:3.1.1'

它支持firebase服务。

希望有人能节省时间。

检查build.gradle中是否有debugCompile和releaseCompile。将其更改为debugImplementation和releaseImplementation。这就是我如何解决它,gradle应该通过这个成功标记的指示弃用,但突然它卡住了这两个。

当我从com.google.android.gms:play-services:11.2.2更新到com.google.android.gms:play-services:11.4.0时,我也遇到了同样的问题。这为我解决了问题:

清洁 重建

一种可能性是:存在相同的库,但依赖项中有不同的版本。

我有这个问题与以下行在gradle文件:

编译文件树(包括:['*.jar'], dir: 'libs') 编译的com.google.code.gson: gson: 2.8.2

gson库在我的libs目录中,但使用的是以前的版本。 我从libs目录中删除了gson-2.3.1.jar,一切都恢复正常了。

如果上面的答案对您不起作用,您的问题可能是您有多个依赖于同一个库的依赖项。

下面是一些调试技巧。在这个示例代码中,com.google.code.findbugs:jsr305:3.0.0是有问题的库。

每次修改以检查解决方案时,都要清理并重新构建!

Build with the --stacktrace flag on for more detail. It will complain about a class, Google that class to find the library. Here's how you can set up Android studio to always run gradle with the --stacktrace flag. Take a glance at the Gradle Console in Android Studio View > Tool Windows > Gradle Console after a build Check for repeated dependences by running ./gradlew -q app:dependencies. You can re-run this each time you modify the your build.gradle. In build.gradle, android { ... configurations.all { resolutionStrategy { // Force a particular version of the library // across all dependencies that have that dependency force 'com.google.code.findbugs:jsr305:3.0.0' } } } In build.gradle, dependencies { ... implementation('com.google.auth:google-auth-library-oauth2-http:0.6.0') { // Exclude the library for this particular import exclude group: 'com.google.code.findbugs' } } In build.gradle, android { ... configurations.all { resolutionStrategy { // Completely exclude the library. Works for transitive // dependencies. exclude group: 'com.google.code.findbugs' } } } If some of your dependencies are in jar files, open up the jar files and see if there are any conflicting class names. If they are, you will probably have to re-build the jars with new class names or look into shading.
