前言

eclipse其实不只是一个桌面（GUI）程序，他还可以是一个命令行程序。如果你的产品或软件是基于eclipse开发的，并且他没有UI相关的功能，那么就可以考虑把这些功能封装为一个独立的application，这样就可以通过命令行，在无界面的情况下去运行

命令行下运行

以eclipse自带的org.eclipse.equinox.p2.director为例，该application主要实现了操作p2仓库的相关功能，比如浏览给定仓库的内容，安装指定插件到指定的eclipse中等等。

–此处假设你已经安装了eclipse sdk或p2相关的插件

# 查看该app的帮助
./eclipse -nosplash -application org.eclipse.equinox.p2.director -help# 列出给定仓库的所有插件
./eclipse -nosplash -application org.eclipse.equinox.p2.director -repository https://download.eclipse.org/releases/2022-12 -list

-nosplash 表示不显示启动页
-application org.eclipse.equinox.p2.director 表示运行id为org.eclipse.equinox.p2.director的application

通过maven tycho运行

</project>

然后执行 mvn clean verify
