问题描述
最近更新Android Studio（2.0.7）之后（也许是原因），有时在构建时会出现该错误。
Recent after update Android Studio (2.0.7) (maybe this is the cause) sometimes when building i get that error.
想法是通常编译会顺利进行但有时我会出现匕首错误。
Idea is that usually compilation goes well but sometimes I get dagger error.
在Dagger配置中是否可能出现问题？
Is possible that is problem in Dagger configuration?
错误本身：
执行任务：[：app：assembleDebug]
Executing tasks: [:app:assembleDebug]
在需求是一个孵化功能。
增量Java编译是一个孵化功能。

出了什么问题：
任务'：app：compileDebugJavaWithJavac'的执行失败。
What went wrong:Execution failed for task ':app:compileDebugJavaWithJavac'.
尝试：
使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行，以获取更多日志输出。
Try:Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

推荐答案
似乎与Gradle 2.10中添加的增量编译有关。
It's seems that it have something to do with incremental compilation added in Gradle 2.10
我设法通过添加以下命令来对其进行修复：
I managed to fix it adding the following command to gradle:
-Pandroid.incrementalJavaCompile=false
您可以在Android Studio中将其添加到：文件|设置|构建，执行，部署|编译器将其添加为命令行选项。
You can add it in Android Studio in: File | Settings | Build, Execution, Deployment | Compiler adding it as a Command line option.
edit 自 2.0起。 0-beta3 插件发出警告，告诉您此选项已添加到Gradle DSL：
edit as of 2.0.0-beta3 the plugin gives a warning telling you that this option has been added to the Gradle DSL:
android {
compileOptions.incremental = false
}
