找不到 Spring Boot Maven 插件类

Question

新手上路，请多包涵

我有三个 maven 项目，一个是 pom 包，另外两个是 jar 包，这里是 admin-aggreagator pom

我没有得到 admin-rest pom.xml 及其主类，因为我缺少的是 ctrl-click 导航到相应的项目，类型搜索能够在 admin-rest 项目中找到主类 ctrl+ shift+T 也变得静止，它显示相同，

            <artifactId>spring-boot-starter-jetty</artifactId>
        </dependency>

    </dependencies>
</project>

主类 AdminRestApp.java，我正在尝试运行管理聚合器

mvn clean spring-boot:run
mvnw.cmd clean spring-boot:run
./mvnw spring-boot:run

但没有一个在工作

package com.sounds.bvs;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class AdminRestApp {

    public static void main(String[] args) {
        SpringApplication.run(AdminRestApp.class, args);
    }
}

and the exception i see class not found exception i tried all which were from similar topic none helped, the start-class tag is also place and hard code the full path com.sounds.bvs.AdminRestApp in mainClass still that also did not help,

我已经尝试更改 spring boot 版本以及 maven 编译器插件版本，它们也有帮助，非常需要帮助。

早些时候包路径很大 com.sounds.bvs.admin.rest 那个时候同样的问题改变了包名也有帮助

请让我知道我缺少什么提前谢谢。

添加 spring boot 版本解决了我的问题。

     <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>2.4.1</version>
        </plugin>
    </plugins>

在 Maven Tab ->plugins 中替换为你的 spring boot 版本
