Eclipse / LibgGdx-如何添加Gradle依赖关系

Question

我正在创建一个LibGdx应用程序，我想使用Mopub为其添加广告。 我目前正在尝试使其在iOS上运行，并且尝试将Mopub Robovm绑定与此处找到的源项目以及已编译的jar （该索引不是存储库，对吗？）作为Gradle依赖项导入，但是在两种情况下，部署时收到此错误：

我认为我遵循了正确实现源项目的步骤，但是我不知道我是否正确地执行了Gradle依赖项。 我为依赖项所做的工作是创建一个文件夹来保存mopub-1.0.0-SNAPSHOT.jar，然后将此调用放入iOS部分下基础项目build.gradle文件的依赖项部分中：

compile files ("libs/mopub-1.0.0-SNAPSHOT.jar")

如果不正确，请告知我正确的方法。 此后，Eclipse告诉我将本地jar放在构建路径上，因为它会产生构建错误，所以我做到了。

该代码正在运行，或者至少正在编译，但是我如何真正地进行部署（如果我做错了，甚至正确地将jar作为Gradle依赖项添加）？

编辑
我使用了compile fileTree ，这实际上将jar放入了Gradle Dependencies中，但是我仍然遇到错误...

将框架CoreData添加到我的robovm.xml文件中可以解决该错误！ 现在，我只需要弄清楚如何将AdManager（由LibGdx推荐的“使用平台特定代码”教程制作的界面）发送到我的主游戏类，因为它只能在didFinishLaunching方法中创建广告。
