The plugin 'org.apache.maven.plugins:maven-eclipse-plugin' does not exist or no valid version could be found 解决

我的maven版本是2.2.1，当我使用mvn eclipse:eclipse命令时出了这个错误：

The plugin 'org.apache.maven.plugins:maven-eclipse-plugin' does not exist or no valid version could be found

 

使用这个命令解决了问题：

mvn -e -DdownloadSources=true eclipse:eclipse  

 

如果问题还存在，建议参考这个帖子：

You should not be using eclipse:eclipse, that target has been deprecated. Instead, install the m2eclipse plugin into Eclipse and use it to create the project.

If we add following in pom.xml in <plugins> section, It will work.

1. <plugin>  
2.             <groupId>org.apache.maven.plugins</groupId>  
3.             <artifactId>maven-eclipse-plugin</artifactId>  
4.             <version>2.7</version>  
5.             <configuration>  
6.                 <sourceIncludes>  
7.                     <sourceInclude>*</sourceInclude>  
8.                 </sourceIncludes>  
9.             </configuration>  
10.         </plugin>  
11.          
12.         <plugin>  
13.            <groupId>org.apache.maven.plugins</groupId>  
14.            <artifactId>maven-plugin-plugin</artifactId>  
15.       </plugin>
