我尝试将Android项目从Maven迁移到Gradle（以及Eclipse迁移到Android Studio）。该项目很大，包含多个模块。切换的主要原因是获得Multidex支持。
为了让我的脚湿透Gradle I，我试图分离并建立一个框架＆＃39;所有其他模块使用的模块。
以下是build.gradle

Total time: 13.957 secs
有没有人遇到过这个？有什么想法吗？
爪哇：
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
答案 0 :(得分：0)
应用这些更改并添加：
android {
lintOptions {
abortOnError false
}
}
它现在已经成功构建，虽然有一堆lint错误，但没有。 耸肩
答案 1 :(得分：0)
Here's来自Dagger问题跟踪器的讨论。似乎匕首隐藏了实际的错误。删除dagger-compiler依赖项，您应该看到错误是什么（似乎是由错误的导入或通配符导入注释引起的）
