Android库拒绝创建R.java，除非构建为com.Android.application

我有一个gradle项目，正在尝试用资产构建一个Android库，并将其作为AAR文件分发。但是，我只能在使用时获取要生成的R.java文件

apply plugin: 'com.android.application'

然后，它将只生成无法用于分发的APK文件。但是，使用“正确的”

拒绝生成R.java文件，因此我的代码都无法编译

我使用的是AndroidStudio 1.2.1，但它拒绝从命令行或IDE内部构建，因此我认为这与此无关

我尝试过重建、清理、确保我的XML文件不被破坏、删除未使用的res文件夹、不使用自定义属性、尝试过多个版本的build tools/gradle/android api版本以及其他相关问题。我还尝试在应用程序和库之间移动内容，但仍然失败

这是我的项目和库build.gradle文件

我最终意识到，主项目的R.java文件实际上包含了正确的id，但我收到了一条令人困惑的错误消息，这让我相信Butterknife注释中的非最终值并不正确。不幸的是，Gradle没有给我一个我能理解的错误

有一些相关的QA，你能检查一下它们是否解决了你的问题吗。谢谢你，帕特里克。不幸的是，我确实读过这些书，但似乎没有一本有用。它似乎直接与库和应用程序android插件的使用有关（或者至少与R文件的生成和否有关）。我没有任何损坏的xmls文件或自定义属性、清理和重建等。这些似乎都没有帮助：（在同步gradle文件后，Android Studio的

gradle

选项卡中是否有名为

processResources

的任务？“gradle选项卡”在哪里？当我运行gradlew任务时，我看不到任何以流程开头的任务。我在Android Studio 1.2下有一个库项目构建。库的build.gradle中的buildscript块看起来有点可疑。在我的项目中，所有存储库配置都在project build.gradle中。依赖项下也有一个存储库块。至少有一个f这些都是多余的。不过，我完全不相信这两个都与您的错误有关。您正在运行的命令是什么？它给了您什么错误输出？
