错误：java.lang.RuntimeException：Proguard-版本（app：transformClassesAndResourcesWithProguardForRelease）

Question

我尝试了Google中存在的所有选项，但没有任何帮助。 在gradle 1.3版本的项目上，但是当在汇编2、2、3发行过程中所有版本都出现错误时。

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
Error:java.lang.RuntimeException: Job failed, see logs for details
Error:java.io.IOException: java.lang.NullPointerException

如果启用，请尝试禁用“即时运行”，然后重建项目。 另外，请查看是否按照此处给出的说明进行了所有设置：
