编译错误包com。fasterxml。杰克逊。批注不存在

Question

下面的类显示问题-导入com。fasterxml。无法解析jackson-

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;


@JsonIgnoreProperties(ignoreUnknown=true)
public class MerchantDetailsDto {

运行干净安装时编译错误-

[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，它位于项目的pom中，该项目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版本-2.10.0。pr1并尝试对依赖项项目进行maven更新，但找不到内部下载的jar。m2、该组件对应的目录结构有两条路径-

.m2/fasterxml/jackson/core/jackson注释

. m 2/repository/com/更快的xml/jackson/core/jackson-注释

我不确定哪一个是实际的版本，所以我尝试从这两个版本中删除现有的版本目录，但当我尝试maven update和clean install时，即使是同一个版本的jar也没有下载。

如有任何指示，我将不胜感激。

更新

依赖项项目上clean install命令的输出-

Answer 1

使用

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

这将引入两个可传递的依赖项：
