maven eclipse:eclipse命令生成的.classpath自动关联源码和javadoc

 方式一:

mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true

方式二：打开maven配置文件 setting.xml文件(.../.m2/settings.xml)   profile节点下增加properties配置：

<profile>
	<id>nexus</id>
	<properties>  
        	<downloadSources>true</downloadSources>  
        	<downloadJavadocs>true</downloadJavadocs>             
    	</properties>
</profile>
