灾难性的初始化失败！正在关闭null WAB，原因为: null // NPE @ WabBundleProcessor.initContext(WabBundleProcessor.java:460)

Question

当我在Lr7门户中部署一个maven module spring mvc portlet Liferay7.3 ga1时，我得到了这个错误，有人能支持吗！是不是少了点什么？

这是堆栈跟踪：

感谢您的支持，谢谢！

我在Liferay7.1上也遇到了同样的问题。

至于我的情况，它是一个maven依赖，当战争建立时，它是缺失的。所以我猜在部署之前你做错了什么。

致以问候。
