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()

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

我遇到了同样的问题,并找到了我的真正原因。 之前我也把之前的所有答案都试了一遍,但是没有解决问题。 我有两个模块在我的穿着应用程序项目,和构建。Gradle如下:

磨损模块的build.gradle:

implementation project(':common')
implementation files('libs/farmer-motion-1.0.jar')

通用模块的build.gradle:

implementation files('libs/farmer-motion-1.0.jar')

在升级到gradle 3之前。X, 'implementation'都是'compile'。

我用——stacktrace选项运行gradlew来获得堆栈跟踪,当出现这个问题时,你可以在gradle控制台窗口上单击这个。并发现依赖于jar包重复:

Caused by: com.android.dex.DexException: Multiple dex files define Lcom/farmer/motion/common/data/pojo/SportSummary$2;

类SportSummary在farmer-motion-1.0.jar包,在阅读官方迁移指南后,我改变了我的构建。Gradle如下:

磨损模块的build.gradle:

implementation project(':common')
// delete dependency implementation files('libs/farmer-motion-1.0.jar')

build.gradle for common module:

api files('libs/farmer-motion-1.0.jar') // change implementation to api

现在磨损模块将有依赖农民运动1.0.jar导出由公共模块。 如果运行时对jar包没有依赖,也可以将jar包的“implementation”依赖更改为“compileOnly”。

其他回答

去Unity >>编辑项目设置>>播放器,寻找缩小部分,然后选择保护选项

我同意小克里斯的观点。如果你正在使用Firebase嵌入AdMob广告(或者你没有使用Firebase),即使你没有将其作为依赖项添加,播放服务分析也会包含播放服务广告。谷歌显然在11.4.0的推广中犯了一个错误,因为分析包括10.0.1版本的广告,而不是11.4.0(鼠标在gradle上的提示显示了这一点)。

我手动添加编译'com.google.android.gms:play-services-ads:11.4.0'在顶部工作,但只有在我禁用立即运行后: http://stackoverflow.com/a/35169716/530047

所以它要么退回到10.0.1,要么添加广告并禁用即时运行。 这就是我的发现,如果有用的话。

可能存在重复的依赖项(可能嵌套在另一个依赖项中)。在命令行中使用"gradlew app:dependencies"来验证你所有的依赖关系。

删除副本后,我的问题就解决了。

试试这个,对我很管用。

在app / build.gradle:

dependencies {
    ....

    compile project(':grow-notification')

    /** Firebase Start **/
    compile 'com.google.firebase:firebase-messaging:11.4.0'
    compile 'com.firebase:firebase-jobdispatcher:0.6.0'
    /** Firebase End **/
}

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

在模块中的growth -notification/build.gradle:

dependencies {
    ....

    /** Firebase Start **/
    provided 'com.google.firebase:firebase-messaging:11.4.0'
    provided 'com.firebase:firebase-jobdispatcher:0.6.0'
    /** Firebase End **/
}

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.
