Eclipse TEA is a tasking orchestration engine that can be run from within the Eclipse IDE or headlessly. It is immediately concerned with tasks related to building and managing plug-ins for the Eclipse Platform, but is general enough to support other types of tasks and builds.
The project includes the necessary code to integrate any language server (conforming to the Language Server Protocol specification) in the Eclipse IDE, interacting with the language server: it orchestrates the request to the language servers and presents the response in the usual IDE metaphors so users can manipulate them. The default integration is to provide features into the Platform's Generic and Extensible editor, but some code may be used as API to let integration be done with other Eclipse-based editors. It's build on top of Eclipse LSP4J.
