java - 找不到Spring Boot Maven插件类

Question

我有三个Maven项目，一个是pom软件包，另外两个是jar包装，这里是admin-aggreagator pom

而且我没有得到admin-rest pom.xml及其主类，因为ctrl-click导航到相应的项目并且类型搜索能够在admin-rest项目ctrl +中找到我想要的主类shift + T也变得静止，显示相同，

</project>

主类AdminRestApp.java，我正在尝试使用以下命令运行admin-aggregator

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

但没有一个工作

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,

我曾尝试更改Spring Boot版本以及Mint编译器插件版本，这也对Dint有所帮助，请帮助非常需要。

较早的软件包路径是大com.sounds.bvs.admin.rest，那个时候同样的问题也改变了软件包名称，这也对

请提前让我知道我想念的是什么。

Answer 1

添加一个 Spring 启动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中用您的Spring Boot版本替换
