No plugin found for prefix 'spring-boot' ...的问题解决方法
我在出初学spring boot时,用idea启动项目没问题,但是用maven启动项目时报错信息如下:
[ERROR] No plugin found for prefix 'spring-boot' in the current project and in t
he plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from th
e repositories [local (C:\Users\Administrator\.m2\repository), alimaven (http://
maven.aliyun.com/nexus/content/groups/public/)] -> [Help 1]

orPrefixException。
国类论坛关于此问题的讨论甚少,之后在国外IT论坛StrackOverflow上找到了解决方法,主要有三种原因:
1.pom.xml里少了parent,代码如下:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.7.RELEASE</version>
</parent>
这种错误几乎不会存在。
2.少了如下代码:
<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>
我找到的帖子的发帖人采纳的就是这个。
3.你运行mvn spring-boot:run
时的路径不对,帖子原文如下:
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.
大致意思就是:
在命令行运行 mvn spring-boot:run
时,一定要确保你是在包含了该pom.xml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。
我就是这个原因,然后到了所含pom.xml的目录下运行mvn spring-boot:run
就顺利启动了。
现在spring boot报错在国内论坛不太容易找到答案,建议大家多用Google,多看外国论坛,英语不好没关系,用百度翻译慢慢看,不要怕,这是成为优秀程序员的必经之路。
