Question

我在我的libgdx游戏中使用Android Studio 2.3.3。我已经更新了从2.14.1到3.3的gradle，当我尝试构建android应用程序时，我收到此错误（桌面版本正常工作）

    Error:Execution failed for task ':android:transformClassesWithDexForRelease'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Landroid/support/compat/R;

我试图降级gradle版本但是对于Android 2.3.3我得到的消息是gradle 3.3是最低要求。

这是我的其他设置

buildToolsVersion '25.0.0'
compileSdkVersion 21

classpath 'com.android.tools.build:gradle:2.3.3'

请有人给我解决这个问题。

编辑：这是我的主要build.gradle文件

Answer 1

Finlay我知道问题是什么。这是一些重复的类问题。我将这行代码放在android，build.gradle文件中，我的项目再次使用gradle 3.3

configurations {
    all*.exclude group: 'com.android.support', module: 'support-v4'
}

我希望这可以帮助别人

降级Gradle

查找gradle-wrapper.properties并更改distributionUrl

distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip

打开root build.gradle文件并在buildscript中找到工件并更改版本

classpath 'com.android.tools.build:gradle:2.3.3'

从root build.gradle文件

中的repo列表中注释/删除google（）
