我在gradle项目中遇到了一个依赖性问题，我不知道如何解决它

我有一个根项目“projectroot”和两个子项目“project-sub-a”和“project-sub-b”。 “project-sub-a”与“project-sub-b”有依赖关系

结构是：

在

/gradlew build

之后，我得到以下错误：

> Task :project-sub-b:compileJava
.../Pojo.java: error: package com.fasterxml.jackson.annotation does not exist
import com.fasterxml.jackson.annotation.JsonProperty;

and more ...

有人知道如何解决这个问题吗？谢谢

看起来您的文件丢失了：

 'com.fasterxml.jackson.core:jackson-annotations:2.10.3'

哪个（和其他几个jackson罐子）是

'org.springframework.boot:spring-boot-starter-web'

这就是项目a不抱怨的原因。因此，无需将jackson放入

子项目中。子项目a无论如何都会得到它。

这就是项目a不抱怨的原因。因此，无需将jackson放入子项目中。子项目a已经收到了。
谢谢。现在它工作了！我从project root:build.gradle中删除了'implementation group:'com.fasterxml.jackson.core'，名称：'jackson core'，版本：'2.10.3'，并将'implementation'org.springframework.boot:spring boot starter web''从project-sub-a:build.gradle移动到project root:build.gradle。但我仍然不明白为什么它以前不起作用。也许“com.fasterxml.jackson.core:jackson注释：2.10.3”是错误的。谢谢。现在它工作了！我从project root:build.gradle中删除了'implementation group:'com.fasterxml.jackson.core'，名称：'jackson core'，版本：'2.10.3'，并将'implementation'org.springframework.boot:spring boot starter web''从project-sub-a:build.gradle移动到project root:build.gradle。但我仍然不明白为什么它以前不起作用。也许“com.fasterxml.jackson.core:jackson注释：2.10.3”是错误的。
