Creating an executable JAR file in Eclipse

Do I have to always click to file/export/executable jar menu?

Is there any way to d开发者_开发问答o this with one button?

(Because for example if I use netbeans and click the clean and build button it will also generate the jar file.)

When you go to Export... -> Java -> JAR File, click next to get to the second page of the wizard. There, you can Save the description of this JAR in the workspace. When the export completes, you should have a .jardesc file. You can right click on this and choose Create JAR for a one step export.
