A build is a process that derives new resources from existing ones, updates existing resources, or both.
In the Workbench, different builders are invoked for different types
of projects. For example, when a build is triggered for a Java project, a Java
builder converts each Java source file (.java files) into one or more executable class files
(.class files). Builders usually enforce the constraints of some
domain. For example, a Web link builder could update links to files
whose name/location changes.
There are two kinds of builds:
An incremental build leverages a
previously built state and applies the transforms of the configured builders
to the resources that have changed since the previous state was computed
(that is, since the last build).
A clean build discards any problems and
previously built state. The next build after a clean will transform all resources according to
the domain rules of the configured builders.
Incremental and clean builds can be done over a specific set of projects or
the workspace as a whole. Specific files and folders cannot be built. There are two ways that builds can be performed:
- Automatic builds are performed as resources are saved. Automatic builds
are always incremental and always operate over the entire workspace. You can
configure your preferences
Window > Preferences > General > Workspace
perform builds automatically on resource modification.
Manual builds are initiated when you explicitly select a menu item or press the
equivalent shortcut key. Manual builds can be either clean or incremental and can operate over collections of projects
or the entire workspace.
