我尝试了Google中存在的所有选项，但没有任何帮助。 在Gradle 1.3项目的版本上，但是当所有的组件在组装2,2,3发布版本错误时。
启用proguard时出错：
Error:java.lang.NullPointerException
Warning:The interface com/github/tibolte/agendacalendarview/agenda/IAgendaHeaderView has a static method "inflate" but backporting default methods is not enabled
Warning:Exception while processing task java.io.IOException: java.lang.NullPointerException
