Spring platform-b​​om和dependencyManagment

Question

我正在尝试使用父项目和子项目来重构一个非常复杂的maven项目。它使用一些Spring Boot和Spring依赖项。在父pom中，<dependencies>下只定义了几个依赖项（在所有子项目中继承的全局依赖项）。其余部分在<dependencyManagement>下定义，以便为整个项目定义一个版本。每个子项目都定义了自己的<dependencies>，而没有设置版本。

但版本管理很混乱;在父pom中，每个依赖项版本都使用全局属性定义。

我想使用平台bom：我尝试过一个父平台-bom。 适用于<dependencies>但不适用于<dependencyManagement>。

在子项目中，未定义版本;有解决方案吗？

'dependencies.dependency.version' for org.springframework.boot:spring-boot-starter-tomcat:jar is missing
