Help Making an Executable jar File in Eclipse

[Kavarria]

I'm trying to make a project into an executable jar file. When it starts exporting, it gives me a compilation error with all the files in my project. However, they compile and execute just fine if I run them in Eclipse.

what is the compilation error you are getting?
Alternativey you can use the jar command to create the executable jar file.
e.g.- jar mcvf ...

just: exported with compile warnings: file name

tell me how to use the jar command?
