线程“主”中的异常java.lang.NoClassDefFoundError：org / springframework / util / StringUtils

Question

当我在SpringBoot中将pom.xml与父项目一起使用时，我有maven多模块项目并且同一个项目运行良好

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

现在，如果我仅将父标记替换为以下标记

<parent>
        <groupId>com.org.ps.uiv</groupId>
        <artifactId>ps-parent</artifactId>
        <version>19.9-SNAPSHOT</version>
    </parent>

它停止工作并出现以下错误

我试图更改spring-core的版本，甚至将其排除在构建之外，但没有固定。

注意-

“父母”项目也添加了与我的模块相关的所有依赖项
