IDEA中找不到maven插件Plugin‘ ‘ not found 解决

1.<artifactId>maven-compiler-plugin</artifactId><version>3.8.0</version>等 报红
1.1首先要找设置File--Settings--Build,..--Maven

1.2然后就继续File--Invalidata Caches

勾选点击这俩个 !!!

点击这个键，再开启idea然后在设置pom.xml文件的代码

      <groupId>org.apache.maven.plugins</groupId>

演示:

   <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-clean-plugin</artifactId>
          <version>3.1.0</version>
        </plugin>
        <!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging -->
        <plugin>
<!--          插入代码-->
            <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-resources-plugin</artifactId>
          <version>3.0.2</version>
        </plugin>
        <plugin>
         <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-compiler-plugin</artifactId>
          <version>3.8.0</version>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>2.22.1</version>
        </plugin>

然后就OK了
