编译错误包com.fasterxml.jackson.annotation不存在

Question

以下课程显示问题 - 无法解决导入 com.fasterxml.jackson -

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;


@JsonIgnoreProperties(ignoreUnknown=true)
public class MerchantDetailsDto {

运行时编译错误clean install-

[ERROR] COMPILATION ERROR : 

[INFO] -------------------------------------------------------------

[ERROR] /Path/to/src/main/java/com/citruspay/common/dto/merchant/MerchantDetailsDto.java:[9,40] package com.fasterxml.jackson.annotation does not exist

[ERROR] /Path/to/src/main/java/com/citruspay/common/dto/merchant/MerchantDetailsDto.java:[11,2] cannot find symbol

  symbol: class JsonIgnoreProperties

pom 定义是这样的，它在一个项目的 pom 中，它被定义为当前项目的依赖项 -

<dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>${jackson-core.version}</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
            <version>${jackson-core.version}</version>
        </dependency>

和

<jackson-core.version>2.6.1</jackson-core.version>

我检查了这个组件的 Maven 存储库，它似乎没有任何依赖项。

我尝试将版本更改为最新的 - 2.10.0.pr1 并尝试对依赖项目进行 maven 更新，但找不到在 .m2 中下载的 jar。这个组件对应的目录结构有两个路径——

.m2/fasterxml/jackson/core/jackson-annotations

.m2/repository/com/fasterxml/jackson/core/jackson-annotations

我不确定其中哪一个是实际的，所以我尝试从这两个中删除现有的版本目录，但是当我尝试 maven update 和 clean install 时，甚至没有下载相同版本的 jar。

将不胜感激任何指针。

更新

依赖项目上的干净安装命令的输出 -

Answer 1

用

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.11.0</version>
    </dependency>

这将引入两个传递依赖项：
