Can Eclipse build specific packages in a project?

I'm curious if there's a way to build specific packages in eclipse. For instance, if I have a project with a src folder containing

c开发者_如何学Pythonom.example.a
com.example.b
com.example.c

Is there a way to build/compile just com.example.a and com.example.c? I know there's a way to do it in ant, but hopefully there's an eclipse solution too.

Yes.

• File
• Export...
• Java
• Jar File

There you can select exactly what to build in Eclipse.

For exampe check only com.example.a and com.example.c.

You can exclude com.example.b from the build path.

For different builds/packages/assemblies (jar files?) you should use ant. That's one reason why it is integrated in eclipse.
