gradle - gradle:带有OSGI/SCR插件的OSGI-INF文件夹的问题

Question

当我尝试生成包含OSGI-INF文件夹信息的OSGI bundle 包时，无法在gradle构建文件中使用apply plugin:'scr'创建该文件夹。请问是否有任何指针？

我正在使用Java 1.8。失败的任务是task ':processScrAnnotations'。

我收到以下异常，该异常未提供有用的消息传递:

您正在使用的gradle插件本身使用的是ASM的较旧版本，该版本不了解Java 8类文件。您需要gradle插件由作者进行更新，以使用确实能够理解Java 8类文件的ASM的最新版本。
