【问题描述】：
我有一个类似于this one 的多模块项目。
我正在使用 Corda 3.2，没有 Kotlin 的 Spring Boot 2，并且由于 cordformation，我有一组 Corda 节点正在运行。我能够从我的 Spring Boot 应用程序成功连接到一个节点，但是在尝试获取 nodeInfo 时遇到了麻烦。
我看到了一个类似的问题here。但是“清除缓存”的答案让我感到困惑。是否意味着清除gradle的缓存？这有什么帮助？
这是我的堆栈跟踪：

我认为其他问题的答案有点无益，它至少应该解释发生了什么以及如何解决这个问题。您能否对该答案发表评论以获取更多信息？
-
好主意，谢谢。我会要求扩展另一个问题的答案。
