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.  <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <version>2.7</version> <configuration> <sourceIncludes> <sourceInclude>*</sourceInclude> </sourceIncludes> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-plugin-plugin</artifactId> </plugin> hey Peter thanks for help. I am also trying the solution you suggested.
