在libGDX项目中使用外部gradle依赖

3

我正在使用LibGDX制作一个Android游戏和外部库。我遇到了以下错误:

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，以便所有我的其他游戏都可以依赖于共同的代码。问题是我的共享库项目除了我的游戏项目外还依赖于Libgdx。当在Android设备上启动我的游戏时， Gradle同步和构建项目都可以正常工作，只有在尝试部署到设备时才会出现问题。我也可以在桌面上部署而没有任何问题。

我认为由于重复的库依赖关系可能超过了65,536个Android方法计数限制，但无法找到更好的解决方案。或者是因为Android不喜欢嵌套的依赖项，这些依赖项不在根目录中。

以下是我的项目结构和Gradle文件。希望能给出一个解决方案，使我可以继续在游戏项目的IDE中编辑库。如果有人推荐其他的项目结构，我也很乐意尝试。

C:\
    Projects\
        SharedProject
        Project1
        Project2
        ...

我的Android模块依赖树（通过运行“gradlew -q dependencies android:dependencies --configuration compile”获得）：

+--- 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：

我尝试了使用multiDexEnabled，但这并没有帮助。

我认为当我将共享库编译到核心时，需要排除gdx模块，但我还没有弄清楚。（我想android不喜欢共享库与android模块具有相同的gdx依赖关系）

另一个可能性是，android需要我的共享项目构建成jar文件，然后放入android模块中的libs文件夹中。这可能可以通过android gradle文件完成，但我对gradle还不熟悉，不知道是否需要这样做或如何操作。

我做出的更改：

将共享项目添加到settings gradle中。

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

在核心模块中添加了对共享项目的依赖

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生成的默认项目结构并没有太多变化。请注意，共享项目是在Intellij中作为新的Gradle项目创建的，而不是使用gdx-setup.jar。下面是完整的Gradle文件。

如果您正在为多个游戏创建通用库，我建议您创建一个包含这些库的单独项目，使用gradle maven-publish插件将其发布到本地maven仓库，然后在游戏项目中声明对这些库的依赖关系。这将有助于您现在调试问题，并使以后修改这些库并在其他游戏中使用它们更加容易。

添加：

compileJava   {
    sourceCompatibility = '1.7'
    targetCompatibility = '1.7'
}

将根gradle文件添加到库项目中，并从库项目中删除settings.gradle文件即可解决问题。

适用于maven本地依赖和外部gradle依赖。
