The Buckminster Project is an Eclipse (software) technology sub-project focused on component assembly. Buckminster facilitates straight forward sharing of complex assemblies of software components. It is particularly useful for building and sharing virtual distros, distributions of software components which share components across multiple software projects and repositories. ==Operation== A Buckminster ''CQUERY (component query)'' names a component assembly. Using a CQUERY, Buckminster can find and locate all the components necessary to complete that particular configuration. Finding needed components includes transitively finding all the components needed by those components. The process which Buckminster implements to transitively locate and then download and install a full set of components for a particular CQUERY is called ''materialization''. A CQUERY is typically published by a developer (or development team) to denote their work: those interested in accessing and using this software can ask Buckminster to fetch everything necessary by quoting the CQUERY. A Buckminster ''RMAP (resource map)'' is associated with a CQUERY, and lists one or more software repositories in which appropriate components can be found. Many popular repository formats are supported, including Concurrent Versions System, Subversion, Apache Maven, Perforce and Eclipse platform infrastructures. A Buckminster ''CSPEC (component specification)'' lists appropriate attributes of a component such as how to build it and on what other components it depends on. CSPECs are frequently automatically generated by Buckminster based on meta-information available elsewhere within repositories and the build environment. Automatically generated CSPECs can be manually via ''CSPECX CSPEC eXtensions". A Buckminster ''BOM (bill of materials)'' lists in full all the details necessary to fulfill a particular CQUERY, and is automatically generated by Buckminster. BOMs are sometimes saved and re-submitted so as to ensure that specific users materialize precisely the same components, in the right versions, as one another. Buckminster CQUERYs, RMAPs, CSPECs and BOMs are specified in XML. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eclipse Buckminster」の詳細全文を読む スポンサード リンク
