If I use command line command like "mvn compile" and "mvn install", I see a jar file under target directory.
如果我使用命令行命令，如“mvn编译”和“mvn安装”，我将看到目标目录下的jar文件。
But if I build the same project from Eclipse using m2e plugin, I don't see a jar file but only compiled class directories under target directory but they are empty. Any insight on this problem?
但是，如果我使用m2e插件从Eclipse构建相同的项目，我不会看到jar文件，但是只在目标目录下编译类目录，但是它们是空的。对这个问题有什么见解吗?

m2e won't build a jar unless you ask it to. (An exception to that is when you're using it with certain connectors to develop OSGi bundles, but I assume you aren't.)
除非你要求，否则m2e不会建一个罐子。(在使用某些连接器来开发OSGi包时，这是一个例外，但我认为您不是。)
To build a jar:
构建一个jar:
- Right-click on the project folder in the 'Package Explorer' view;
- 右键单击“Package Explorer”视图中的项目文件夹;
- Select "Run As"
- 选择“运行”
- Select "Maven install"
- 选择“Maven安装”
