No plugin found for prefix spring-boot in the current project and in the plugin groups 异常解决

一. 异常问题

我在intellij idea中通过mvn spring-boot:run命令来启动springboot项目的时候,结果产生如下图所示的异常信息:

异常现象

No plugin found for prefix spring-boot in the current project and in the plugin groups 异常解决

[ERROR] No plugin found for prefix 'spring-boot' in the current 

project and in the plugin groups [org.apache.maven.plugins, 

org.codehaus.mojo] available from the repositories [local (C:MavenRepository), central 

(https://repo.maven.apache.org/maven2)] -> [Help 1]

二. 原因分析

产生该问题的原因大致有如下三种:

1. pom.xml文件里少了parent依赖,代码如下:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.7.RELEASE</version>
 </parent>

这种错误一般不会存在。

2. 缺少如下代码:

<repositories>
    <repository>
        <id>spring-releases</id>
        <url>https://repo.spring.io/libs-release</url>
    </repository>
</repositories>
<pluginRepositories>
    <pluginRepository>
        <id>spring-releases</id>
        <url>https://repo.spring.io/libs-release</url>
    </pluginRepository>
</pluginRepositories>

3. 运行mvn spring-boot:run 命令时的路径不对:

If you are running the mvn spring-boot:run from the command line, 

make sure you are in the directory that contains the pom.xml file. 

Otherwise, you will run into the No plugin found for prefix ‘spring-

boot’ in the current project and in the plugin groups error.

意思是: 在命令行运行 mvn spring-boot:run 时,一定要确保你是运行在该pom.xml文件所在的路径下,不然就会出现 No plugin found for prefix 'spring-boot' in the current project and in the plugin groups 这种错误。

三. 解决办法

大多数人都是这个原因,只要切换到pom.xml文件所在的目录下运行mvn spring-boot:run 就顺利启动了。
