修改spring-boot-starter-data-redis依赖后，spring-data-redis版本为何不符预期？

我修改了spring-boot-starter-data-redis的pom.xml文件，将spring-data-redis的版本指定为2.1.4.RELEASE，重新编译该starter为2.1.19.BUILD-SNAPSHOT版本并执行本地安装命令mvn clean install -DskipTests，随后在新项目fm_hello中引用该版本的spring-boot-starter-data-redis。但发现实际使用的spring-data-redis版本为2.1.21.RELEASE，而非预期的2.1.4.RELEASE。

期望 #

我期望在fm_hello项目中引入2.1.19.BUILD-SNAPSHOT版本的spring-boot-starter-data-redis后，底层使用的spring-data-redis版本为2.1.4.RELEASE。
