spring-boot在执行org.springframework.boot时缺少必需的类：spring-boot-maven-plugin：1.4.0.RELEASE：repackage

Question

我使用eclipse学习spring引导。我创建了一个简单的应用程序，但当我运行它使用mvn spring-boot:run我得到错误。我有一个主类

public static void main(String[] args) { 
     System.out.println("----START----"); 
     SpringApplication.run(TestApplication.class, args); 
} 

这是我的POM样子

我该如何解决这个问题？我试过清洗，安装和重新包装，但没有任何工作

你的pom.xml应该是这样的。在父项中包含“relativePath”。

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 
<modelVersion>4.0.0</modelVersion>

    <relativePath />  
</parent> 

<properties> 
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

</properties> 

<dependencies> 
    <dependency> 
     <groupId>org.springframework.boot</groupId>

    </dependency> 


</dependencies> 

<build> 
    <plugins>

      <artifactId>spring-boot-maven-plugin</artifactId> 
     </plugin> 
    </plugins> 
</build> 
</project> 

而且你的Java主类

package com.Inventory; 
import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 

@SpringBootApplication 
public class TestApplication{ 
public static void main(String[] args) { 
    System.out.println("----START----"); 
    SpringApplication.run(TestApplication.class, args); 
    } 
}
