How to tell Eclipse to generate a *.jar instead of classes? [message #512061]

Is there a way to tell Eclipse not only to generate classes but to automatically create a Manifest and put everything into a target.jar archive?

How do I do this?

If you're trying to write a build script, then write a build script. Implement your required tasks in an Ant build.xml and either run it from the command line or from Eclipse.

So the only way is through Ant script built.xml

There is no menu or option within Eclipse itself?

Have you looked at File / Export / Java / Jar File?

Namaste, Bruce

Bruce's solution is fine. You can even save your "export" description as a ".jardesc" file, so you can regenerate the jar in just two clicks time Razz

Furthermore, if your gonna reference the project from a J2EE project (say a web application, for instance), the "J2EE module dependencies" is your friend here, as you can refer to the project and Eclipse will "jar" it by itself.

Hope this helps.

Ok, I can create a jar file with

File / Export / Java / Jar File

but how do I create the mentioned .jardesc file?
I found no appropriate option for that.
Is it automatically created? Where is it stored?

Can I automatically let Eclipse create and equivalent Ant Script?

After selecting the JAR name in the JAR export wizard, click to "Next"
and check "Save the description of this JAR in the workspace". Then
specify where to save and hit "Next" or "Finish".
