如何使用java运行自定义jar文件副本到classpath命令？

I have a jar file which I'm using to run as an application. However, every time I run my application I need to add -cp "jar name" to compile it and then run the java application.

我有一个jar文件,我用它作为一个应用程序运行。但是,每次运行我的应用程序时,我都需要添加-cp“jar name”来编译它,然后运行java应用程序。

How can I make a permanent change so that I don't have to use the command line commands for this task? Can I put that in certain lib location?

如何进行永久性更改,以便我不必使用命令行命令执行此任务?我可以把它放在某个lib位置吗?

Note: I don't have to use any IDE. It has to be from a terminal.

注意:我不必使用任何IDE。它必须来自一个终端。

One more solution: extension libraries, put your jar into $JAVA_HOME/lib/ext
