Inadequate errror message - Lifecycle mapping "org.eclipse.m2e.jdt.JarLifecycleMapping" is not available.

VS Code extension emits an inadequate error message Lifecycle mapping "org.eclipse.m2e.jdt.JarLifecycleMapping" is not available. To enable full functionality, install the lifecycle mapping and run Maven->Update Project Configuration. whenever the underlying service has a problem with an internal error (see https://github.com/eclipse/eclipse.jdt.ls/issues/866)

Environment

• Operating System: Linux Fedora 29
• JDK version: 10.0.2
• Visual Studio Code version: 0.34.0
• Java extension version: ???

Steps To Reproduce

See https://github.com/eclipse/eclipse.jdt.ls/issues/866 for producing an internal error in Eclipse base.

Current Result

Error message: "Lifecycle mapping "org.eclipse.m2e.jdt.JarLifecycleMapping" is not available."

Expected Result

Error message: Internal error in language service (+ actionable steps for reporting / diagnosing)

Iniziare con la riproduzione dell’errore interno descritta in eclipse/jdt.ls#866 e tracciare il punto in cui viene emesso il messaggio di lifecycle-mapping nell’estensione VS Code. Il lavoro è completato quando l’estensione segnala un errore interno del servizio linguistico con passaggi concreti per segnalarlo o diagnosticarlo, invece del messaggio di lifecycle-mapping fuorviante.
