maven出现Unresolved plugin: 'org.apache.maven.plugins:maven-resources-plugin:2.6'

环境：jdk1.8、maven3.6.3、idea2021版

settings.xml配置如下

  
/usr/local/maven3.6.3/maven_repo
  
      
              alimaven
              aliyun maven
              http://maven.aliyun.com/nexus/content/groups/public/
              central        
    
  

使用idea新建maven项目出现错误

Unresolved plugin: 'org.apache.maven.plugins:maven-jar-plugin:2.4'
Unresolved plugin: 'org.apache.maven.plugins:maven-compiler-plugin:3.1'
