The configuration for an Element, represented in YAML format.
The output collected after building an Element.
BuildStream leverages various caching techniques in order to avoid duplicating work.
- Core plugin
A Plugin that is contained in the BuildStream package. These are built-in and don’t need to be defined in the project configuration.
See plugin documentation for more details on core plugins.
Elements in a BuildStream project can depend on other elements from the same project. The element dependent upon is called a dependency.
See Dependencies document for more details.
An atom of a BuildStream project. Projects consist of zero or more elements.
Configuration for elements is stored in form of :term:
.bstfile>` See Declaring Elements document for more details on element configurtion.
- External Plugin
A Plugin that is defined in some package other than BuildStream.
External plugins must be declared in the project configuration.
For a list of known external plugin repositories, see External plugins.
A special kind of Element, that allows you to depend on elements from another project.
Junction referencefor details on how to configure junction elements.
See Junction guide for details on how to use junction elements.
- Local Cache
To avoid duplicating work, BuildStream will cache sources, artifacts, logs, buildtrees etc. in a local cache directory. If these sources or artifacts are needed another time, BuildStream will use them from the cache.
See Local cache expiry section of the user guide for details on how to configure the local cache.
A collection of Elements.
Elements in a project share some central configuration. See Project configuration to learn how to configure BuildStream projects.
- Remote Cache
See cache server documentation for details on artifact caches.
Sources describe the input to the build of an Element.
In general, an element can have zero or more sources. But, certain element plugins may restrict the number of allowed sources.
Workspaces allow building one or more elements using a local, and potentially modified, copy of their sources.
See Workspaces guide for more details on how to use workspaces.
