解决“程序包com.alibaba.fastjson不存在”的错误（导入瑞吉外卖项目）

article 2024/10/23 6:58:09

1.查看maven文件夹下的com文件夹

没有alibaba这个文件夹

2.配置阿里云镜像库

配置settings.xml

注意两点：

1.localRepository是本地仓库的地址（上图）

2.配置镜像

    <mirrors>
        <mirror>  
            <id>alimaven</id>  
            <name>aliyun maven</name>  
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
            <mirrorOf>central</mirrorOf>          
        </mirror>  
      </mirrors>

3.刷新maven

假如以上两步都做完，但是问题还没有解决，

在项目终端输入

mvn clean install

3.mysql依赖导入报错

ERROR] [ERROR] Some problems were encountered while processing the POMs: [ERROR] 'dependencies.dependency.version' for mysql:mysql-connector-java:jar is missing. @ line 67, column 21 @ [ERROR] The build could not read 1 project -> [Help 1] [ERROR] [ERROR] The project org.example:reggie:1.0-SNAPSHOT (D:\hm-code\reggie\pom.xml) has 1 error [ERROR] 'dependencies.dependency.version' for mysql:mysql-connector-java:jar is missing. @ line 67, column 21 [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

好像是让导入版本号但是导入了好像也不行

根据下面那篇博客知：是因为springboor版本过高写成这样就可以了‘dependencies.dependency.version‘ for mysql:mysql-connector-java:jar is missing.问题处理_dependencies.dependency.version' for mysql:mysql-c-CSDN博客
