If you have a downloaded project, first you have to import it:
如果你有一个下载的项目，首先你必须导入它：
- Go to project explorer
- Right click
- Select import
- If it is a war file choose as it or import as file system. There are many choices there. After that you have to add REQUIRED JARon its class path, or if its a web projectyou have to add REQUIRED JARin
WEB_INF/lib folder.
- 转到项目浏览器
- 右键点击
- 选择导入
- 如果是war文件，选择 as it 或 import as file system。那里有很多选择。之后，你必须添加所需的JAR其对类路径，或者如果它是一个Web项目必须添加所需的JAR在
WEB_INF/lib folder。

Depends a bit on what kind of project this is..... Eclipse supports different kinds of launchers for different kinds of projects.
取决于这是什么类型的项目..... Eclipse 支持不同类型的项目的不同类型的启动器。
But assuming it's a relatively standard Java project, just right click on the main class and do "Run As... / Java Application".
但是假设它是一个相对标准的Java项目，只需右键单击主类并执行“Run As... / Java Application”。
This should launch your application, and Eclipse will remember this configuration the next time you try to run.
这应该会启动您的应用程序，Eclipse 将在您下次尝试运行时记住此配置。
