我正在设置一个新的多模块 maven 项目，我想在其中使用：

Spring boot
Vaadin 13
Wildfly-13

当我尝试部署战争时，我得到

"18:16:17,130 WARN  [org.jboss.modules.define] (MSC service thread 1-3) Failed to define class org.springframework.http.server.reactive.AbstractListenerWriteProcessor in Module "deployment.universe-web-2.1.4.RELEASE.war" 
from Service Module Loader: java.lang.NoClassDefFoundError: Failed to link org/springframework/http/server/reactive/AbstractListenerWriteProcessor"

我认为问题在于如何描述不同模块中的依赖关系。我的项目结构：宇宙

-- universe-model
-- universe-repository
-- universe-service
-- universe-ui
-- universe-utils
-- universe-web

目前，我只是尝试启动简单的 vaadin 单页 web ui。我试图删除 wildfly 独立文件夹，但没有成功。

此外，我尝试将依赖项从 Universe-web 移动到 Universe-ui，但没有任何运气。下面的 pom 代表了我认为正确的当前情况。

我的聚合器 pom 文件如下所示：

我将 pom 文件更改为以下内容，现在它工作得很好：
