定义-在更新Magnolia 5.5.7之后，App在开始时抛出一个异常

Question

我正在测试Magnolia升级到5.5.7版的可能性(从5.3.14版本)，到目前为止，我们的项目已经完全工作了，并且在启动时没有收到警告。

我遵循了Magnolia文档中建议的更新步骤：https://documentation.magnolia-cms.com/display/DOCS/Updating+Magnolia

但是当我尝试打开定义应用程序时，它使用的子应用程序“概述”抛出了一个NullPointerException，我不知道为什么。

即使在删除和重新创建整个存储库时，错误仍然存在，因此我认为它与依赖关系有关，不幸的是，我对Magnolia中的依赖关系不太了解--我只是使用推荐的包和版本，再加上我们以前编译项目时使用的版本。

有人能告诉我为什么会出现这个错误吗？

更新：

将木兰更新为版本5.6，用Bloe3.2修正了我的错误

Answer 1

我猜你撞到https://jira.magnolia-cms.com/browse/PSWDMNGR-7了

尝试排除密码管理器模块，或者用1.0.1-SNAPSHOT替换它的版本，解决这个问题(不要使用1.2，这只兼容w/ Magnolia 5.6)。
