我正在尝试设置一个依赖于其他两个库模块的Android库模块.我们使用android.support.annotation框架在一些方法上添加注释.当我尝试构建aar时,这就是我得到的:
:hce_entry:extractReleaseAnnotations FAILED
Error:Execution failed for task ':hce_entry:extractReleaseAnnotations'.
> java.lang.NullPointerException (no error message)
我尝试使用--stacktrace选项获取更多信息来执行gradle构建,这是输出:
...
:hce_entry:extractReleaseAnnotations FAILED
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':hce_entry:extractReleaseAnnotations'.
java.lang.NullPointerException (no error message)
Try:
Run with --info or --debug option to get more log output.
Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':hce_entry:extractReleaseAnnotations'.
