Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information.
The project includes the necessary code to integrate any language server (conforming to the Language Server Protocol specification) or Debug Adapter (conforming to the Debug Adapter Protocol) in the Eclipse IDE: it orchestrates the requests to the language servers or debug adapters 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.
