From the Builders panel, you can specify which builders to enable for this project and
in which order they are run.

-
Configure the builders for the project
- This list lets you select or deselect individual builders to run
(by checking their boxes) and to define the order in which they are run.
-
New
- Opens the Choose configuration type dialog so that you can add a new builder to
the list.

The Program option lets you to define an external tool for
any executable file that is accessible on your local or network filesystem.
For example, if instead of the Ant builder you prefer to use your own shell
scripts or Windows .bat files to package and deploy
your Eclipse projects, you can then create a Program external tool that
would specify where and how to execute that script.

include it in the list.

selected builder.

You can select from these options:

- During manual builds — The build
is initiated when you explicitly select a menu item
or press its corresponding shortcut key sequence.
- During auto builds — Automatic builds
are performed as resources are saved (they are
incremental and operate over an entire workspace). Note that running
your project builder during auto builds is possible, although it is not
recommended because of performance concerns.

is scheduled to run during a clean operation.
