Gradle Build Error - 在app：compileDebugJava gradle任务期间抛出NullPointerException

时间：2014-07-09 17:29:27

标签： android gradle android-studio ormlite dagger

每次尝试进行gradle构建时，我都会一直收到此错误消息。我最近在此之前进行了构建，并且创建了应用程序而没有任何问题。我没有对build.gradle文件进行任何更改。造成这种情况的原因是什么？

:app:preBuild
 ......
:app:processDebugResources
:app:generateDebugSources
:app:compileDebugJava FAILED
Error:Execution failed for task ':app:compileDebugJava'.
> java.lang.NullPointerException

我使用的是Android Studio版本0.8.1

这是gradle stacktrace：

我认为Support library repository outdated. Downloading update...与导致您遇到麻烦的NullPointerException无关。此消息来自sdk-manager-plugin，可能与以下sdk-manager-plugin的问题有关：https://github.com/JakeWharton/sdk-manager-plugin/issues/31。至于提到的NPE，它由dagger库抛出。您最近是否对与dagger相关的代码进行了任何更改？
