这个错误通常是由于 Maven 没有正确加载 Spring Boot 插件导致的。你可以尝试以下步骤：

1. 确认你的 Maven 版本是否支持 Spring Boot 插件。Spring Boot 2.4.x 版本需要 Maven 3.6.0 或更高版本才能正常工作。

2. 确认你的 Maven 配置文件（settings.xml）是否正确配置了镜像和仓库。可以参考以下配置：

<mirrors>
  <mirror>
    <id>aliyun</id>
    <mirrorOf>*</mirrorOf>
    <name>阿里云公共仓库</name>
    <url>https://maven.aliyun.com/repository/public</url>
  </mirror>
</mirrors>

<profiles>
  <profile>
    <id>default</id>
    <repositories>
      <repository>
        <id>aliyun</id>
        <url>https://maven.aliyun.com/repository/public</url>
        <releases>
          <enabled>true</enabled>
        </releases>
        <snapshots>
          <enabled>false</enabled>
        </snapshots>
      </repository>
    </repositories>
    <pluginRepositories>
      <pluginRepository>
        <id>aliyun</id>
        <url>https://maven.aliyun.com/repository/public</url>
        <releases>
          <enabled>true</enabled>
        </releases>
        <snapshots>
          <enabled>false</enabled>
        </snapshots>
      </pluginRepository>
    </pluginRepositories>
  </profile>
</profiles>

3. 确认你的 pom.xml 文件是否正确引入了 Spring Boot 插件。可以参考以下配置：

<build>
  <plugins>
    <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
      <version>2.4.4</version>
    </plugin>
  </plugins>
</build>

希望这些步骤可以帮助你解决问题！
