The CDT Build System Take 2
This is an attempt at taking a step back and mapping out what the CDT build system should be given all the requirements of the day and in an effort to simplify the existing system.
The Model
These are the core classes that define the CDT build model.
Target Platform
The target platform describes the execution environment that the build output is intended to run on. Different target platforms use different tool chains and produce different kinds of build targets. They may also used different builder.
Tool
A tool is a process that takes input targets and produces output targets. The targets can be resources or pseudo targets. Build Targets are selected from the collection of output targets. Pseudo input targets must also be output targets somewhere in the build. The targets are used to build up a dependency graph that is used to decide which tools to run in what order.
Tools have properties that control options in the behavior of the tool. Tools may be external utilities and the properties serve to generate command lines. Tools may also be internal utilities, although these can not be called from external builders (and probably should be discouraged or this ability dropped).
Tool Chain
Is the collection of tools used for a given build. A tool chain supports a given Target Platform. Predefined tool chains can be reused at project creation time. Tools can be added by the user, or automatically based on the resources in the project (e.g. a code generator for model files).
Builder
The builder is the component responsible for doing the build when Eclipse calls for one. The builder could call an external utility or utilities to do the build, or could be an internal builder that calls tools directly. The builder may also wish to generate files to the filesystem to manage the build as changes are made to the resources or the build settings.
Build Target
This is the end result of the build. Generally there is only one, but there could be more if the builder supports that. The build target can be a resource or a pseudo target. It should be possible to model 'make' targets with this class.
Configuration
A configuration is a mapping of Builder, Build Target, and Tool Chain. Tools option settings are per configuration. Also files and folders can be excluded from the build in a given configuration of the builder supports that.
