Gradle脚本，用于选择Android库的构建变体
我正在使用Eclipse和Android项目。我不能使用Android Studio有很多原因。不幸的是，Eclipse不能使用AAR归档。经过长期的努力，我们决定让Eclipse项目成为非GRADLE项目（从所有Eclipse项目中消除GRADLE性质），并用一个特殊的GRADLE脚本准备一个依赖项列表。 为了能够使用Android，我编写了以下gradle脚本，它执行以下操作：Gradle脚本，用于选择Android库的构建变体,android,eclipse,gradle,Android,Eclipse,Gradle,我正在使用Eclipse和Android项目。我不能使用Android Studio有很多原因。不幸的是，Eclipse不能使用AAR归档。经过长期的努力，我们决定让Eclipse项目成为非GRADLE项目（从所有Eclipse项目中消除GRADLE性质），并用一个特殊的GRADLE脚本准备一个依赖项列表。 为了能够使用Android，我编写了以下gradle脚本，它执行以下操作： 搜索所有项目中的所有依赖项 将依赖项从gradle缓存复制到一个特殊的Eclipse项目“jars from gr
