Question

我正在使用LibGDX开发Android游戏和外部库。我收到以下错误：

Error:Execution failed for task ':android:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: 
    org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Android\Android Studio\jre\bin\java.exe'' 
    finished with non-zero exit value 1

我正在尝试创建一个外部共享项目，我的所有其他游戏都可以依赖于该公共代码。问题是我的共享库项目取决于Libgdx以及我的游戏项目，它依赖于libgdx。在Android设备上启动我的游戏时。 gradle sync和build项目工作正常，只有在尝试部署到设备上时才会发生。我也可以毫无问题地部署到桌面。

我认为由于重复的库依赖性，我可能超过了Android方法计数限制65,536，但是无法找到更好的解决方案。或者它可能是因为android不喜欢根目录中没有的嵌套依赖项。

我在下面提供了我的项目结构和gradle文件。非常感谢一个允许我继续在游戏项目的IDE中编辑库的解决方案。如果有人推荐别的东西，我也愿意接受另一个项目结构。

目录/项目结构：

C:\
    Projects\
        SharedProject
        Project1
        Project2
        ...

我的android模块依赖树（通过运行＆＃34; gradlew -q依赖项android：dependencies --configuration compile＆＃34;）：

+--- project :core
|    +--- com.badlogicgames.gdx:gdx:1.9.6
|    \--- project :APD_Core
|         \--- com.badlogicgames.gdx:gdx:1.9.6
\--- com.badlogicgames.gdx:gdx-backend-android:1.9.6
     \--- com.badlogicgames.gdx:gdx:1.9.6

（注意：APD_Core是共享项目）

可能的解决方案：

我曾尝试使用multiDexEnabled，但这没有帮助。我想在将共享库编译成核心时可能需要排除gdx模块但我还没有解决这个问题。（我认为android不喜欢对android模块也有gdx具有相同依赖性的共享库）另一种可能性是android需要将我的共享项目构建到jar中，然后放入android模块中的libs文件夹中。这可能是通过android gradle文件来实现的，但我是新手，并且不知道这是否需要或如何做。

我改变了什么：

将共享项目添加到设置gradle

include ':APD_Core'
project(':APD_Core').projectDir = new File(settingsDir, '../APD_Core')

将依赖项添加到核心模块中的共享项目

project(":core") {
    ...
    dependencies {
        ...
        compile project(':APD_Core')
    }
}

让共享项目依赖于libgdx

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
    compile "com.badlogicgames.gdx:gdx:$gdxVersion"
}

使用gdx-setup.jar时，默认生成的项目结构没有其他变化请注意，共享项目是从intellij创建的，作为新的gradle项目，而不是使用gdx-setup.jar 完整的gradle文件吼叫

Answer 1

如果您要为许多游戏制作通用库，我建议您创建一个包含这些库的单独项目，使用gradle maven-publish plugin将其发布到您当地的maven仓库，然后声明这些库的依赖关系在你的游戏项目中。这将帮助您现在调试您的问题，并且将来更容易修改这些库并在将来的其他游戏中使用它们。

Answer 2

添加：

{}

到库项目的根gradle文件，从库项目中删除settings.gradle文件解决了这个问题。

适用于maven本地依赖项和外部gradle依赖项。

外部gradle对libGDX项目的依赖
