问题：
I want to import existing Maven project into Eclipse.我想将现有的 Maven 项目导入 Eclipse。 I found 2 ways to do it:我找到了两种方法：
- Through running from command line
mvn eclipse:eclipse通过从命令行运行mvn eclipse:eclipse - To install Maven Eclipse plugin from Eclipse.从 Eclipse 安装 Maven Eclipse 插件。
What is the difference between the both and which one is preferable?两者之间有什么区别，哪个更可取？
If I install Maven Eclipse plugin through the Eclipse menu Help -> Install New Software , do I still need to modify my pom.xml to include the Maven Eclipse plugin in the plugins section?如果我通过 Eclipse 菜单Help -> Install New Software安装 Maven Eclipse 插件，我还需要修改我的pom.xml以在插件部分包含 Maven Eclipse 插件吗？
